The '''EF 50mm lenses''' are a group of [[normal lens|normal]] [[prime lens|prime]] [[photographic lens|lenses]] made by [[Canon (company)|Canon]] that share the same [[focal length]]. These lenses are based on the classic [[double-Gauss lens]],<ref>http://www.canon.com/camera-museum/camera/lens/ef/data/standard/ef_50_18ii.html?p=1 {{dead link|date=March 2015}}</ref> with the f/1.8 being a standard six-element double-Gauss with an air gap and powers between element 2 and 3<ref>[http://www.canon.com/camera-museum/camera/lens/ef/data/standard/ef_50_18ii.html?p=2] {{dead link|date=March 2015}}</ref> and its [[Lens speed|faster]] cousins adding additional elements.<ref>[http://www.canon.com/camera-museum/camera/lens/ef/standard.html] {{dead link|date=March 2015}}</ref> The 50mm focal length, when used with a 35mm film or full-frame sensor, has been widely considered to match the perspective seen by the human eye.<ref>[http://www.vothphoto.com/spotlight/articles/forgotten_lens/forgotten-lens.htm 50mm and the Human Eye], ''Gary Voth''. Retrieved 2011-01-10.</ref>

Canon 50mm lenses have an [[Canon EF lens mount|EF]] type mount that fits the Canon [[Canon EOS|EOS]] line of cameras. When pairing a 50mm lens to a Canon DSLR with an [[APS-C]] sized sensor, the [[crop factor]] effectively turns the 50mm focal length into a 80mm field of view.

Six EF 50mm lenses have been sold by Canon:

==EF 50mm {{f/}}1.0L USM==
The discontinued '''EF 50mm {{f/}}1.0L [[Ultrasonic motor|USM]]''' is a professional L series autofocus lens. On the used market sells for as much as double the original retail value.{{fact|date=October 2008}} It was the fastest [[Single Lens Reflex|SLR]] lens in production during its lifetime.<ref name="canonmuseum_ef50f10l"/> This lens has a metal body and mount, and plastic extremities. It also features a wide rubber focus ring that is [[Damping|damped]], a distance window with [[Infrared photography|infrared]] index, and the ability to set the focus range from 0.6m to infinity, or 1m to infinity. In common with the [[Canon EF 85mm lens|EF 85mm f/1.2L USM]] it uses an electronic "focus by wire" system and requires power from the camera in order to manual focus. The 8-blade diaphragm and maximum [[aperture]] of {{f/}}1.0 give this lens the ability to create extremely shallow [[depth of field]] effects and to support low light situations. The optical construction of this lens contains 11 lens elements, including two ground and polished [[Aspheric lens|aspherical lens]] elements. This lens uses a floating front extension [[Focus (optics)|focusing]] system, powered by a ring-type USM motor. The front of the lens does not rotate, but does extend when focusing.

Despite its price and large maximum aperture, the 1.0L was not a particularly sharp lens at any aperture, and the two cheaper 50mm options offered far better sharpness when stopped down beyond about {{f/}}2.8.<ref>{{cite web|url=http://www.wlcastleman.com/equip/reviews/50mm/index.htm|title=Review of the Canon EF 50mm f/1.0L USM Lens, EF 50mm f/1.4 USM lens,
and EF 50mm f/1.8 II Lens|work=wlcastleman.com}}</ref> This, combined with the high production cost and low sales volume, led to it being discontinued in 2000 and eventually superseded by the {{f/}}1.2 edition.

==EF 50mm {{f/}}1.2L USM==
The '''EF 50mm {{f/}}1.2L [[Ultrasonic motor|USM]]''' is a professional L series lens designed to replace the '''EF 50mm {{f/}}1.0L USM'''. It is constructed with a metal body and mount, and plastic extremities. This lens features a wide rubber focusing ring that is damped, a distance window with infrared index, and is fully weather-sealed, when a filter is added to the front. A circular, 8-blade diaphragm and maximum aperture of {{f/}}1.2 give this lens the ability to create very shallow depth of field effects with smooth background blur. The optical construction of this lens contains 8 lens elements, including one ground and polished aspherical lens element. This lens uses a floating front extension focusing system, powered by a ring-type USM motor. The front of the lens does not rotate or extend when focusing.

==EF 50mm {{f/}}1.4 USM==
[[File:Canon EF 50mm f1.4.jpg|thumb|EF 50mm f/1.4 USM, showing its large maximum aperture; at {{f/}}1.4 and 50 mm, the [[entrance pupil]] diameter is 35.7 mm.]]
The '''EF 50mm {{f/}}1.4 USM''' is a consumer- and professional-level lens. It is the least expensive {{f/}}1.4 aperture lens that Canon currently manufactures. It is constructed with a plastic body and a metal mount. This lens features a distance window with infrared index. An 8-blade diaphragm and maximum aperture of {{f/}}1.4 give this lens the ability to create shallow depth of field effects. The optical construction of this lens contains 7 lens elements including 2 high refraction elements, but no aspherical, high dispersion or [[calcium fluoride]] elements. The lens uses a front extension focusing system, powered by a micro [[Ultrasonic motor|USM]] motor. Even though this lens uses a micro USM motor, it still has FTM (full-time manual focus) available. Auto-focus speed of this lens is fast, but not as quick as most ring-USM-based lenses. The front of the lens does not rotate, but extends by up to about one centimeter when focusing.
{{-}}

==EF 50mm {{f/}}1.8==
The '''EF 50mm {{f/}}1.8''' is an economy level lens (discontinued in 1990), which has been replaced by the '''EF 50mm {{f/}}1.8 II'''. The body is plastic but the lens mount is metal, and it features a distance window with infrared index. A 5 blade maximum aperture of {{f/}}1.8 gives this lens the ability to create depth of field effects.

The optical construction of this lens contains 6 lens elements, with no special elements. This lens uses a front extension focusing system, powered by an AFD motor. The front of the lens does not rotate when focusing, making it compatible with circular polarisers.

Although auto-focus speed, despite the AFD motor, is moderately fast but audible, the lens is still very popular.

Because of its low price (it is sold used only) and very sharp optical quality, this lens has earned the preference of a lot of photographers. Obviously, when shooting at f/1.8, it offers a very shallow depth of field which is beneficial for isolating subjects against a blurred background (bokeh).

==EF 50mm {{f/}}1.8 II==
[[File:Brahma-at-wat-chedi-liam-wiang-kum-kam-chiang-mai-thailand.jpg|thumb|left|Black and white image taken with EF 50mm f/1.8 II demonstrating depth of field at f/6.3 ([/media/wikipedia/commons/4/4f/Brahma-at-wat-chedi-liam-wiang-kum-kam-chiang-mai-thailand.jpg view at full size])]]
[[File:Canon EF 50 mm f 1.8 II.jpg|thumb|The EF 50mm f/1.8 II]]
The '''EF 50mm {{f/}}1.8 II''' replaced the '''EF 50mm {{f/}}1.8''' in 1991. The '''EF 50mm {{f/}}1.8 II''' has lost the metal lens mount, the distance scale, the IR focusing label and the separate manual focusing ring that came with the original '''EF 50mm {{f/}}1.8'''.

The current '''EF 50mm {{f/}}1.8 II''' lens has a plastic lens mount. The manual focusing ring has been replaced by a very small thin focusing ring on the front tip of the lens. However the lens does not suffer from rotating front lens element and can be used with [[Polarizing filter (photography)|polarizing filters]]. The optics for both lenses are identical, with 6 elements in 5 groups and a 5 blade diaphragm. Nevertheless, some photographers think the original '''EF 50mm {{f/}}1.8''' is slightly better {{Dubious|date=May 2014}} {{Citation needed|date=May 2014}}. Both lenses have a 52mm filter thread.

Because of its low price and sharp optical quality, this lens has earned the nicknames 'nifty fifty' and 'plastic fantastic'. When shooting at f/1.8, it offers a very shallow [[depth of field]] which is beneficial for isolating subjects against a blurred background ([[bokeh]]).

==EF 50mm {{f/}}1.8 STM==
Canon introduced the EF 50mm {{f/}}1.8 STM on May 10, 2015. This lens utilizes Canon's STM focusing motor, which supports the Movie Servo autofocus mode. The lens features a metal mount and has a rounded seven-blade aperture. Its filter diameter of 49mm is the smallest among all lenses in the family.<ref>{{cite web|url=http://www.usa.canon.com/cusa/about_canon/newsroom?pageKeyCode=pressreldetail&docId=0901e02480f0929b|title=

==EF 50mm {{f/}}2.5 Compact Macro==
[[Image:Damsel fly cropped - Canon 50mm compact macro.jpg|thumb|left|Close-up taken with 50mm Compact Macro]]
[[Image:Canon EF 50mm Compact Macro extended.jpg|thumb|right|upright|Canon EF 50mm compact macro with inner lens barrel extended]]
[[Image:Canon LIFE-SIZE Converter.jpg|thumb|right|upright|Canon LIFE-SIZE Converter for the EF 50mm f/2.5 Compact Macro to get a magnification up to 1:1]]
The '''EF 50mm f/2.5 Compact Macro''' is a relatively inexpensive [[Macro photography|macro]] lens with a minimum focusing distance of 23cm (9 inches) offering a maximum magnification of 0.5x actual size.<ref name="canonmuseum_ef50f25" /> Reviewers describe the lens as having "decent"/"mid-level" build quality, with very good color and contrast, "absolutely negligible" distortion, very sharp after f/4 and peak performance at f/5.6. However, auto-focusing is relatively slow and noisy.<ref>{{cite web |title=Canon EF 50mm f/2.5 macro - Review / Test Report - Analysis |url=http://www.photozone.de/canon-eos/161-canon-ef-50mm-f25-macro-test-report--review?start=1 |publisher=Photozone |accessdate=2010-06-18 }}</ref><ref>{{cite web |title=Canon EF 50mm f/2.5 Macro Lens Review |first=Bryan |last=Carnathan |publisher=The-Digital-Picture.com |url=http://www.the-digital-picture.com/Reviews/Canon-EF-50mm-f-2.5-Compact-Macro-Lens-Review.aspx |accessdate=2010-06-18}}</ref>

The maximum 0.5x magnification means this lens is more suitable for photographing documents, products and objects at least 5cm (2 inches) wide than small insects etc. The outer barrel is grooved to accept Canon's MR-14 [[ring flash]] which can be used as the principal light source for close-ups or as on-axis [[Fill light|fill lighting]] for portraits. The six-blade [[Diaphragm (optics)|diaphragm]] provides reasonably good out-of-focus blur ([[bokeh]]) for portrait work.

First introduced in 1987, it is the oldest lens in Canon's current lineup ({{as of|2014|1|lc=on}}) that is still available new.<ref>{{cite web |url=http://www.the-digital-picture.com/News/News-Post.aspx?News=8777 |title=What are the 10 Oldest Canon Lenses Currently Available? |first=Bryan |last=Carnathan |publisher=The-Digital-Picture.com |date=January 9, 2014 |accessdate=January 10, 2014}}</ref> The lens is constructed with a plastic body and metal mount, and features a distance window with infrared index and magnification markings. The optional '''Life-Size Converter EF'''<ref name="canonusa1">{{cite web|url=http://www.usa.canon.com/consumer/controller?act=ModelInfoAct&fcategoryid=155&modelid=8121|title=Life-Size Converter EF|work=Canon USA|author=[[Canon Inc.]]|accessdate=2007-10-15}}</ref> adapts the lens to produce a maximum magnification of 1:1. Attaching the converter increases the lens focal length to 70mm, reduces the maximum aperture to {{f/}}3.5 and limits the focal range. Magnification markings for the converter are shown on the (extending) inner lens barrel.

==EF 50mm {{f/}}1.0L USM==
The discontinued '''EF 50mm {{f/}}1.0L [[Ultrasonic motor|USM]]''' is a professional L series autofocus lens. On the used market sells for as much as double the original retail value.{{fact|date=October 2008}} It was the fastest [[Single Lens Reflex|SLR]] lens in production during its lifetime.<ref name="canonmuseum_ef50f10l"/> This lens has a metal body and mount, and plastic extremities. It also features a wide rubber focus ring that is [[Damping|damped]], a distance window with [[Infrared photography|infrared]] index, and the ability to set the focus range from 0.6m to infinity, or 1m to infinity. In common with the [[Canon EF 85mm lens|EF 85mm f/1.2L USM]] it uses an electronic "focus by wire" system and requires power from the camera in order to manual focus. The 8-blade diaphragm and maximum [[aperture]] of {{f/}}1.0 give this lens the ability to create extremely shallow [[depth of field]] effects and to support low light situations. The optical construction of this lens contains 11 lens elements, including two ground and polished [[Aspheric lens|aspherical lens]] elements. This lens uses a floating front extension [[Focus (optics)|focusing]] system, powered by a ring-type USM motor. The front of the lens does not rotate, but does extend when focusing.

Despite its price and large maximum aperture, the 1.0L was not a particularly sharp lens at any aperture, and the two cheaper 50mm options offered far better sharpness when stopped down beyond about {{f/}}2.8.<ref>{{cite web|url=http://www.wlcastleman.com/equip/reviews/50mm/index.htm|title=Review of the Canon EF 50mm f/1.0L USM Lens, EF 50mm f/1.4 USM lens,
and EF 50mm f/1.8 II Lens|work=wlcastleman.com}}</ref> This, combined with the high production cost and low sales volume, led to it being discontinued in 2000 and eventually superseded by the {{f/}}1.2 edition.

==EF 50mm {{f/}}1.2L USM==
The '''EF 50mm {{f/}}1.2L [[Ultrasonic motor|USM]]''' is a professional L series lens designed to replace the '''EF 50mm {{f/}}1.0L USM'''. It is constructed with a metal body and mount, and plastic extremities. This lens features a wide rubber focusing ring that is damped, a distance window with infrared index, and is fully weather-sealed, when a filter is added to the front. A circular, 8-blade diaphragm and maximum aperture of {{f/}}1.2 give this lens the ability to create very shallow depth of field effects with smooth background blur. The optical construction of this lens contains 8 lens elements, including one ground and polished aspherical lens element. This lens uses a floating front extension focusing system, powered by a ring-type USM motor. The front of the lens does not rotate or extend when focusing.

==EF 50mm {{f/}}1.4 USM==
[[File:Canon EF 50mm f1.4.jpg|thumb|EF 50mm f/1.4 USM, showing its large maximum aperture; at {{f/}}1.4 and 50 mm, the [[entrance pupil]] diameter is 35.7 mm.]]
The '''EF 50mm {{f/}}1.4 USM''' is a consumer- and professional-level lens. It is the least expensive {{f/}}1.4 aperture lens that Canon currently manufactures. It is constructed with a plastic body and a metal mount. This lens features a distance window with infrared index. An 8-blade diaphragm and maximum aperture of {{f/}}1.4 give this lens the ability to create shallow depth of field effects. The optical construction of this lens contains 7 lens elements including 2 high refraction elements, but no aspherical, high dispersion or [[calcium fluoride]] elements. The lens uses a front extension focusing system, powered by a micro [[Ultrasonic motor|USM]] motor. Even though this lens uses a micro USM motor, it still has FTM (full-time manual focus) available. Auto-focus speed of this lens is fast, but not as quick as most ring-USM-based lenses. The front of the lens does not rotate, but extends by up to about one centimeter when focusing.
{{-}}

==EF 50mm {{f/}}1.8==
The '''EF 50mm {{f/}}1.8''' is an economy level lens (discontinued in 1990), which has been replaced by the '''EF 50mm {{f/}}1.8 II'''. The body is plastic but the lens mount is metal, and it features a distance window with infrared index. A 5 blade maximum aperture of {{f/}}1.8 gives this lens the ability to create depth of field effects.

The optical construction of this lens contains 6 lens elements, with no special elements. This lens uses a front extension focusing system, powered by an AFD motor. The front of the lens does not rotate when focusing, making it compatible with circular polarisers.

Although auto-focus speed, despite the AFD motor, is moderately fast but audible, the lens is still very popular.

Because of its low price (it is sold used only) and very sharp optical quality, this lens has earned the preference of a lot of photographers. Obviously, when shooting at f/1.8, it offers a very shallow depth of field which is beneficial for isolating subjects against a blurred background (bokeh).

==EF 50mm {{f/}}1.8 II==
[[File:Brahma-at-wat-chedi-liam-wiang-kum-kam-chiang-mai-thailand.jpg|thumb|left|Black and white image taken with EF 50mm f/1.8 II demonstrating depth of field at f/6.3 ([/media/wikipedia/commons/4/4f/Brahma-at-wat-chedi-liam-wiang-kum-kam-chiang-mai-thailand.jpg view at full size])]]
[[File:Canon EF 50 mm f 1.8 II.jpg|thumb|The EF 50mm f/1.8 II]]
The '''EF 50mm {{f/}}1.8 II''' replaced the '''EF 50mm {{f/}}1.8''' in 1991. The '''EF 50mm {{f/}}1.8 II''' has lost the metal lens mount, the distance scale, the IR focusing label and the separate manual focusing ring that came with the original '''EF 50mm {{f/}}1.8'''.

The current '''EF 50mm {{f/}}1.8 II''' lens has a plastic lens mount. The manual focusing ring has been replaced by a very small thin focusing ring on the front tip of the lens. However the lens does not suffer from rotating front lens element and can be used with [[Polarizing filter (photography)|polarizing filters]]. The optics for both lenses are identical, with 6 elements in 5 groups and a 5 blade diaphragm. Nevertheless, some photographers think the original '''EF 50mm {{f/}}1.8''' is slightly better {{Dubious|date=May 2014}} {{Citation needed|date=May 2014}}. Both lenses have a 52mm filter thread.

Because of its low price and sharp optical quality, this lens has earned the nicknames 'nifty fifty' and 'plastic fantastic'. When shooting at f/1.8, it offers a very shallow [[depth of field]] which is beneficial for isolating subjects against a blurred background ([[bokeh]]).

==EF 50mm {{f/}}1.8 STM==
Canon introduced the EF 50mm {{f/}}1.8 STM on May 10, 2015. This lens utilizes Canon's STM focusing motor, which supports the Movie Servo autofocus mode. The lens features a metal mount and has a rounded seven-blade aperture.<ref>{{cite web|url=http://www.usa.canon.com/cusa/about_canon/newsroom?pageKeyCode=pressreldetail&docId=0901e02480f0929b|title=

==EF 50mm {{f/}}2.5 Compact Macro==
[[Image:Damsel fly cropped - Canon 50mm compact macro.jpg|thumb|left|Close-up taken with 50mm Compact Macro]]
[[Image:Canon EF 50mm Compact Macro extended.jpg|thumb|right|upright|Canon EF 50mm compact macro with inner lens barrel extended]]
[[Image:Canon LIFE-SIZE Converter.jpg|thumb|right|upright|Canon LIFE-SIZE Converter for the EF 50mm f/2.5 Compact Macro to get a magnification up to 1:1]]
The '''EF 50mm f/2.5 Compact Macro''' is a relatively inexpensive [[Macro photography|macro]] lens with a minimum focusing distance of 23cm (9 inches) offering a maximum magnification of 0.5x actual size.<ref name="canonmuseum_ef50f25" /> Reviewers describe the lens as having "decent"/"mid-level" build quality, with very good color and contrast, "absolutely negligible" distortion, very sharp after f/4 and peak performance at f/5.6. However, auto-focusing is relatively slow and noisy.<ref>{{cite web |title=Canon EF 50mm f/2.5 macro - Review / Test Report - Analysis |url=http://www.photozone.de/canon-eos/161-canon-ef-50mm-f25-macro-test-report--review?start=1 |publisher=Photozone |accessdate=2010-06-18 }}</ref><ref>{{cite web |title=Canon EF 50mm f/2.5 Macro Lens Review |first=Bryan |last=Carnathan |publisher=The-Digital-Picture.com |url=http://www.the-digital-picture.com/Reviews/Canon-EF-50mm-f-2.5-Compact-Macro-Lens-Review.aspx |accessdate=2010-06-18}}</ref>

The maximum 0.5x magnification means this lens is more suitable for photographing documents, products and objects at least 5cm (2 inches) wide than small insects etc. The outer barrel is grooved to accept Canon's MR-14 [[ring flash]] which can be used as the principal light source for close-ups or as on-axis [[Fill light|fill lighting]] for portraits. The six-blade [[Diaphragm (optics)|diaphragm]] provides reasonably good out-of-focus blur ([[bokeh]]) for portrait work.

First introduced in 1987, it is the oldest lens in Canon's current lineup ({{as of|2014|1|lc=on}}) that is still available new.<ref>{{cite web |url=http://www.the-digital-picture.com/News/News-Post.aspx?News=8777 |title=What are the 10 Oldest Canon Lenses Currently Available? |first=Bryan |last=Carnathan |publisher=The-Digital-Picture.com |date=January 9, 2014 |accessdate=January 10, 2014}}</ref> The lens is constructed with a plastic body and metal mount, and features a distance window with infrared index and magnification markings. The optional '''Life-Size Converter EF'''<ref name="canonusa1">{{cite web|url=http://www.usa.canon.com/consumer/controller?act=ModelInfoAct&fcategoryid=155&modelid=8121|title=Life-Size Converter EF|work=Canon USA|author=[[Canon Inc.]]|accessdate=2007-10-15}}</ref> adapts the lens to produce a maximum magnification of 1:1. Attaching the converter increases the lens focal length to 70mm, reduces the maximum aperture to {{f/}}3.5 and limits the focal range. Magnification markings for the converter are shown on the (extending) inner lens barrel.

The '''EF 50mm lenses''' are a group of [[normal lens|normal]] [[prime lens|prime]] [[photographic lens|lenses]] made by [[Canon (company)|Canon]] that share the same [[focal length]]. These lenses are based on the classic [[double-Gauss lens]],<ref>http://www.canon.com/camera-museum/camera/lens/ef/data/standard/ef_50_18ii.html?p=1 {{dead link|date=March 2015}}</ref> with the f/1.8 being a standard six-element double-Gauss with an air gap and powers between element 2 and 3<ref>[http://www.canon.com/camera-museum/camera/lens/ef/data/standard/ef_50_18ii.html?p=2] {{dead link|date=March 2015}}</ref> and its [[Lens speed|faster]] cousins adding additional elements.<ref>[http://www.canon.com/camera-museum/camera/lens/ef/standard.html] {{dead link|date=March 2015}}</ref> The 50mm focal length, when used with a 35mm film or full-frame sensor, has been widely considered to match the perspective seen by the human eye.<ref>[http://www.vothphoto.com/spotlight/articles/forgotten_lens/forgotten-lens.htm 50mm and the Human Eye], ''Gary Voth''. Retrieved 2011-01-10.</ref>

Canon 50mm lenses have an [[Canon EF lens mount|EF]] type mount that fits the Canon [[Canon EOS|EOS]] line of cameras. When pairing a 50mm lens to a Canon DSLR with an [[APS-C]] sized sensor, the [[crop factor]] effectively turns the 50mm focal length into a 80mm field of view.

Six EF 50mm lenses have been sold by Canon:

==EF 50mm {{f/}}1.0L USM==
The discontinued '''EF 50mm {{f/}}1.0L [[Ultrasonic motor|USM]]''' is a professional L series autofocus lens. On the used market sells for as much as double the original retail value.{{fact|date=October 2008}} It was the fastest [[Single Lens Reflex|SLR]] lens in production during its lifetime.<ref name="canonmuseum_ef50f10l"/> This lens has a metal body and mount, and plastic extremities. It also features a wide rubber focus ring that is [[Damping|damped]], a distance window with [[Infrared photography|infrared]] index, and the ability to set the focus range from 0.6m to infinity, or 1m to infinity. In common with the [[Canon EF 85mm lens|EF 85mm f/1.2L USM]] it uses an electronic "focus by wire" system and requires power from the camera in order to manual focus. The 8-blade diaphragm and maximum [[aperture]] of {{f/}}1.0 give this lens the ability to create extremely shallow [[depth of field]] effects and to support low light situations. The optical construction of this lens contains 11 lens elements, including two ground and polished [[Aspheric lens|aspherical lens]] elements. This lens uses a floating front extension [[Focus (optics)|focusing]] system, powered by a ring-type USM motor. The front of the lens does not rotate, but does extend when focusing.

Despite its price and large maximum aperture, the 1.0L was not a particularly sharp lens at any aperture, and the two cheaper 50mm options offered far better sharpness when stopped down beyond about {{f/}}2.8.<ref>{{cite web|url=http://www.wlcastleman.com/equip/reviews/50mm/index.htm|title=Review of the Canon EF 50mm f/1.0L USM Lens, EF 50mm f/1.4 USM lens,
and EF 50mm f/1.8 II Lens|work=wlcastleman.com}}</ref> This, combined with the high production cost and low sales volume, led to it being discontinued in 2000 and eventually superseded by the {{f/}}1.2 edition.

==EF 50mm {{f/}}1.2L USM==
The '''EF 50mm {{f/}}1.2L [[Ultrasonic motor|USM]]''' is a professional L series lens designed to replace the '''EF 50mm {{f/}}1.0L USM'''. It is constructed with a metal body and mount, and plastic extremities. This lens features a wide rubber focusing ring that is damped, a distance window with infrared index, and is fully weather-sealed, when a filter is added to the front. A circular, 8-blade diaphragm and maximum aperture of {{f/}}1.2 give this lens the ability to create very shallow depth of field effects with smooth background blur. The optical construction of this lens contains 8 lens elements, including one ground and polished aspherical lens element. This lens uses a floating front extension focusing system, powered by a ring-type USM motor. The front of the lens does not rotate or extend when focusing.

==EF 50mm {{f/}}1.4 USM==
[[File:Canon EF 50mm f1.4.jpg|thumb|EF 50mm f/1.4 USM, showing its large maximum aperture; at {{f/}}1.4 and 50 mm, the [[entrance pupil]] diameter is 35.7 mm.]]
The '''EF 50mm {{f/}}1.4 USM''' is a consumer- and professional-level lens. It is the least expensive {{f/}}1.4 aperture lens that Canon currently manufactures. It is constructed with a plastic body and a metal mount. This lens features a distance window with infrared index. An 8-blade diaphragm and maximum aperture of {{f/}}1.4 give this lens the ability to create shallow depth of field effects. The optical construction of this lens contains 7 lens elements including 2 high refraction elements, but no aspherical, high dispersion or [[calcium fluoride]] elements. The lens uses a front extension focusing system, powered by a micro [[Ultrasonic motor|USM]] motor. Even though this lens uses a micro USM motor, it still has FTM (full-time manual focus) available. Auto-focus speed of this lens is fast, but not as quick as most ring-USM-based lenses. The front of the lens does not rotate, but extends by up to about one centimeter when focusing.
{{-}}

==EF 50mm {{f/}}1.8==
The '''EF 50mm {{f/}}1.8''' is an economy level lens (discontinued in 1990), which has been replaced by the '''EF 50mm {{f/}}1.8 II'''. The body is plastic but the lens mount is metal, and it features a distance window with infrared index. A 5 blade maximum aperture of {{f/}}1.8 gives this lens the ability to create depth of field effects.

The optical construction of this lens contains 6 lens elements, with no special elements. This lens uses a front extension focusing system, powered by an AFD motor. The front of the lens does not rotate when focusing, making it compatible with circular polarisers.

Although auto-focus speed, despite the AFD motor, is moderately fast but audible, the lens is still very popular.

Because of its low price (it is sold used only) and very sharp optical quality, this lens has earned the preference of a lot of photographers. Obviously, when shooting at f/1.8, it offers a very shallow depth of field which is beneficial for isolating subjects against a blurred background (bokeh).

==EF 50mm {{f/}}1.8 II==
[[File:Brahma-at-wat-chedi-liam-wiang-kum-kam-chiang-mai-thailand.jpg|thumb|left|Black and white image taken with EF 50mm f/1.8 II demonstrating depth of field at f/6.3 ([/media/wikipedia/commons/4/4f/Brahma-at-wat-chedi-liam-wiang-kum-kam-chiang-mai-thailand.jpg view at full size])]]
[[File:Canon EF 50 mm f 1.8 II.jpg|thumb|The EF 50mm f/1.8 II]]
The '''EF 50mm {{f/}}1.8 II''' replaced the '''EF 50mm {{f/}}1.8''' in 1991. The '''EF 50mm {{f/}}1.8 II''' has lost the metal lens mount, the distance scale, the IR focusing label and the separate manual focusing ring that came with the original '''EF 50mm {{f/}}1.8'''.

The current '''EF 50mm {{f/}}1.8 II''' lens has a plastic lens mount. The manual focusing ring has been replaced by a very small thin focusing ring on the front tip of the lens. However the lens does not suffer from rotating front lens element and can be used with [[Polarizing filter (photography)|polarizing filters]]. The optics for both lenses are identical, with 6 elements in 5 groups and a 5 blade diaphragm. Nevertheless, some photographers think the original '''EF 50mm {{f/}}1.8''' is slightly better {{Dubious|date=May 2014}} {{Citation needed|date=May 2014}}. Both lenses have a 52mm filter thread.

Because of its low price and sharp optical quality, this lens has earned the nicknames 'nifty fifty' and 'plastic fantastic'. When shooting at f/1.8, it offers a very shallow [[depth of field]] which is beneficial for isolating subjects against a blurred background ([[bokeh]]).

==EF 50mm {{f/}}1.8 STM==
Canon introduced the EF 50mm {{f/}}1.8 STM on May 10, 2015. This lens utilizes Canon's STM focusing motor, which supports the Movie Servo autofocus mode. The lens features a metal mount and has a rounded seven-blade aperture.<ref>{{cite web|url=http://www.usa.canon.com/cusa/about_canon/newsroom?pageKeyCode=pressreldetail&docId=0901e02480f0929b|title=

==EF 50mm {{f/}}2.5 Compact Macro==
[[Image:Damsel fly cropped - Canon 50mm compact macro.jpg|thumb|left|Close-up taken with 50mm Compact Macro]]
[[Image:Canon EF 50mm Compact Macro extended.jpg|thumb|right|upright|Canon EF 50mm compact macro with inner lens barrel extended]]
[[Image:Canon LIFE-SIZE Converter.jpg|thumb|right|upright|Canon LIFE-SIZE Converter for the EF 50mm f/2.5 Compact Macro to get a magnification up to 1:1]]
The '''EF 50mm f/2.5 Compact Macro''' is a relatively inexpensive [[Macro photography|macro]] lens with a minimum focusing distance of 23cm (9 inches) offering a maximum magnification of 0.5x actual size.<ref name="canonmuseum_ef50f25" /> Reviewers describe the lens as having "decent"/"mid-level" build quality, with very good color and contrast, "absolutely negligible" distortion, very sharp after f/4 and peak performance at f/5.6. However, auto-focusing is relatively slow and noisy.<ref>{{cite web |title=Canon EF 50mm f/2.5 macro - Review / Test Report - Analysis |url=http://www.photozone.de/canon-eos/161-canon-ef-50mm-f25-macro-test-report--review?start=1 |publisher=Photozone |accessdate=2010-06-18 }}</ref><ref>{{cite web |title=Canon EF 50mm f/2.5 Macro Lens Review |first=Bryan |last=Carnathan |publisher=The-Digital-Picture.com |url=http://www.the-digital-picture.com/Reviews/Canon-EF-50mm-f-2.5-Compact-Macro-Lens-Review.aspx |accessdate=2010-06-18}}</ref>

The maximum 0.5x magnification means this lens is more suitable for photographing documents, products and objects at least 5cm (2 inches) wide than small insects etc. The outer barrel is grooved to accept Canon's MR-14 [[ring flash]] which can be used as the principal light source for close-ups or as on-axis [[Fill light|fill lighting]] for portraits. The six-blade [[Diaphragm (optics)|diaphragm]] provides reasonably good out-of-focus blur ([[bokeh]]) for portrait work.

First introduced in 1987, it is the oldest lens in Canon's current lineup ({{as of|2014|1|lc=on}}) that is still available new.<ref>{{cite web |url=http://www.the-digital-picture.com/News/News-Post.aspx?News=8777 |title=What are the 10 Oldest Canon Lenses Currently Available? |first=Bryan |last=Carnathan |publisher=The-Digital-Picture.com |date=January 9, 2014 |accessdate=January 10, 2014}}</ref> The lens is constructed with a plastic body and metal mount, and features a distance window with infrared index and magnification markings. The optional '''Life-Size Converter EF'''<ref name="canonusa1">{{cite web|url=http://www.usa.canon.com/consumer/controller?act=ModelInfoAct&fcategoryid=155&modelid=8121|title=Life-Size Converter EF|work=Canon USA|author=[[Canon Inc.]]|accessdate=2007-10-15}}</ref> adapts the lens to produce a maximum magnification of 1:1. Attaching the converter increases the lens focal length to 70mm, reduces the maximum aperture to {{f/}}3.5 and limits the focal range. Magnification markings for the converter are shown on the (extending) inner lens barrel.

The '''EF 50mm lenses''' are a group of [[normal lens|normal]] [[prime lens|prime]] [[photographic lens|lenses]] made by [[Canon (company)|Canon]] that share the same [[focal length]]. These lenses are based on the classic [[double-Gauss lens]],<ref>http://www.canon.com/camera-museum/camera/lens/ef/data/standard/ef_50_18ii.html?p=1 {{dead link|date=March 2015}}</ref> with the f/1.8 being a standard six-element double-Gauss with an air gap and powers between element 2 and 3<ref>[http://www.canon.com/camera-museum/camera/lens/ef/data/standard/ef_50_18ii.html?p=2] {{dead link|date=March 2015}}</ref> and its [[Lens speed|faster]] cousins adding additional elements.<ref>[http://www.canon.com/camera-museum/camera/lens/ef/standard.html] {{dead link|date=March 2015}}</ref> The 50mm focal length, when used with a 35mm film or full-frame sensor, has been widely considered to match the perspective seen by the human eye.<ref>[http://www.vothphoto.com/spotlight/articles/forgotten_lens/forgotten-lens.htm 50mm and the Human Eye], ''Gary Voth''. Retrieved 2011-01-10.</ref>

Canon 50mm lenses have an [[Canon EF lens mount|EF]] type mount that fits the Canon [[Canon EOS|EOS]] line of cameras. When pairing a 50mm lens to a Canon DSLR with an [[APS-C]] sized sensor, the [[crop factor]] effectively turns the 50mm focal length into a 80mm field of view.

Six EF 50mm lenses have been sold by Canon:

==EF 50mm {{f/}}1.0L USM==
The discontinued '''EF 50mm {{f/}}1.0L [[Ultrasonic motor|USM]]''' is a professional L series autofocus lens. On the used market sells for as much as double the original retail value.{{fact|date=October 2008}} It was the fastest [[Single Lens Reflex|SLR]] lens in production during its lifetime.<ref name="canonmuseum_ef50f10l"/> This lens has a metal body and mount, and plastic extremities. It also features a wide rubber focus ring that is [[Damping|damped]], a distance window with [[Infrared photography|infrared]] index, and the ability to set the focus range from 0.6m to infinity, or 1m to infinity. In common with the [[Canon EF 85mm lens|EF 85mm f/1.2L USM]] it uses an electronic "focus by wire" system and requires power from the camera in order to manual focus. The 8-blade diaphragm and maximum [[aperture]] of {{f/}}1.0 give this lens the ability to create extremely shallow [[depth of field]] effects and to support low light situations. The optical construction of this lens contains 11 lens elements, including two ground and polished [[Aspheric lens|aspherical lens]] elements. This lens uses a floating front extension [[Focus (optics)|focusing]] system, powered by a ring-type USM motor. The front of the lens does not rotate, but does extend when focusing.

Despite its price and large maximum aperture, the 1.0L was not a particularly sharp lens at any aperture, and the two cheaper 50mm options offered far better sharpness when stopped down beyond about {{f/}}2.8.<ref>{{cite web|url=http://www.wlcastleman.com/equip/reviews/50mm/index.htm|title=Review of the Canon EF 50mm f/1.0L USM Lens, EF 50mm f/1.4 USM lens,
and EF 50mm f/1.8 II Lens|work=wlcastleman.com}}</ref> This, combined with the high production cost and low sales volume, led to it being discontinued in 2000 and eventually superseded by the {{f/}}1.2 edition.

==EF 50mm {{f/}}1.2L USM==
The '''EF 50mm {{f/}}1.2L [[Ultrasonic motor|USM]]''' is a professional L series lens designed to replace the '''EF 50mm {{f/}}1.0L USM'''. It is constructed with a metal body and mount, and plastic extremities. This lens features a wide rubber focusing ring that is damped, a distance window with infrared index, and is fully weather-sealed, when a filter is added to the front. A circular, 8-blade diaphragm and maximum aperture of {{f/}}1.2 give this lens the ability to create very shallow depth of field effects with smooth background blur. The optical construction of this lens contains 8 lens elements, including one ground and polished aspherical lens element. This lens uses a floating front extension focusing system, powered by a ring-type USM motor. The front of the lens does not rotate or extend when focusing.

==EF 50mm {{f/}}1.4 USM==
[[File:Canon EF 50mm f1.4.jpg|thumb|EF 50mm f/1.4 USM, showing its large maximum aperture; at {{f/}}1.4 and 50 mm, the [[entrance pupil]] diameter is 35.7 mm.]]
The '''EF 50mm {{f/}}1.4 USM''' is a consumer- and professional-level lens. It is the least expensive {{f/}}1.4 aperture lens that Canon currently manufactures. It is constructed with a plastic body and a metal mount. This lens features a distance window with infrared index. An 8-blade diaphragm and maximum aperture of {{f/}}1.4 give this lens the ability to create shallow depth of field effects. The optical construction of this lens contains 7 lens elements including 2 high refraction elements, but no aspherical, high dispersion or [[calcium fluoride]] elements. The lens uses a front extension focusing system, powered by a micro [[Ultrasonic motor|USM]] motor. Even though this lens uses a micro USM motor, it still has FTM (full-time manual focus) available. Auto-focus speed of this lens is fast, but not as quick as most ring-USM-based lenses. The front of the lens does not rotate, but extends by up to about one centimeter when focusing.
{{-}}

==EF 50mm {{f/}}1.8==
The '''EF 50mm {{f/}}1.8''' is an economy level lens (discontinued in 1990), which has been replaced by the '''EF 50mm {{f/}}1.8 II'''. The body is plastic but the lens mount is metal, and it features a distance window with infrared index. A 5 blade maximum aperture of {{f/}}1.8 gives this lens the ability to create depth of field effects.

The optical construction of this lens contains 6 lens elements, with no special elements. This lens uses a front extension focusing system, powered by an AFD motor. The front of the lens does not rotate when focusing, making it compatible with circular polarisers.

Although auto-focus speed, despite the AFD motor, is moderately fast but audible, the lens is still very popular.

Because of its low price (it is sold used only) and very sharp optical quality, this lens has earned the preference of a lot of photographers. Obviously, when shooting at f/1.8, it offers a very shallow depth of field which is beneficial for isolating subjects against a blurred background (bokeh).

[[File:Canon EF 50 mm f 1.8 II.jpg|thumb|The EF 50mm f/1.8 II]]
The '''EF 50mm {{f/}}1.8 II''' replaced the '''EF 50mm {{f/}}1.8''' in 1991. The '''EF 50mm {{f/}}1.8 II''' has lost the metal lens mount, the distance scale, the IR focusing label and the separate manual focusing ring that came with the original '''EF 50mm {{f/}}1.8'''.

The current '''EF 50mm {{f/}}1.8 II''' lens has a plastic lens mount. The manual focusing ring has been replaced by a very small thin focusing ring on the front tip of the lens. However the lens does not suffer from rotating front lens element and can be used with [[Polarizing filter (photography)|polarizing filters]]. The optics for both lenses are identical, with 6 elements in 5 groups and a 5 blade diaphragm. Nevertheless, some photographers think the original '''EF 50mm {{f/}}1.8''' is slightly better {{Dubious|date=May 2014}} {{Citation needed|date=May 2014}}. Both lenses have a 52mm filter thread.

Because of its low price and sharp optical quality, this lens has earned the nicknames 'nifty fifty' and 'plastic fantastic'. When shooting at f/1.8, it offers a very shallow [[depth of field]] which is beneficial for isolating subjects against a blurred background ([[bokeh]]).

==EF 50mm {{f/}}1.8 STM==
Canon introduced the EF 50mm {{f/}}1.8 STM on May 10, 2015. This lens utilizes Canon's STM focusing motor, which supports the Movie Servo autofocus mode. The lens features a metal mount and has a rounded seven-blade aperture.<ref>{{cite web|url=http://www.usa.canon.com/cusa/about_canon/newsroom?pageKeyCode=pressreldetail&docId=0901e02480f0929b|title=

[[Image:Canon LIFE-SIZE Converter.jpg|thumb|right|upright|Canon LIFE-SIZE Converter for the EF 50mm f/2.5 Compact Macro to get a magnification up to 1:1]]
The '''EF 50mm f/2.5 Compact Macro''' is a relatively inexpensive [[Macro photography|macro]] lens with a minimum focusing distance of 23cm (9 inches) offering a maximum magnification of 0.5x actual size.<ref name="canonmuseum_ef50f25" /> Reviewers describe the lens as having "decent"/"mid-level" build quality, with very good color and contrast, "absolutely negligible" distortion, very sharp after f/4 and peak performance at f/5.6. However, auto-focusing is relatively slow and noisy.<ref>{{cite web |title=Canon EF 50mm f/2.5 macro - Review / Test Report - Analysis |url=http://www.photozone.de/canon-eos/161-canon-ef-50mm-f25-macro-test-report--review?start=1 |publisher=Photozone |accessdate=2010-06-18 }}</ref><ref>{{cite web |title=Canon EF 50mm f/2.5 Macro Lens Review |first=Bryan |last=Carnathan |publisher=The-Digital-Picture.com |url=http://www.the-digital-picture.com/Reviews/Canon-EF-50mm-f-2.5-Compact-Macro-Lens-Review.aspx |accessdate=2010-06-18}}</ref>

The maximum 0.5x magnification means this lens is more suitable for photographing documents, products and objects at least 5cm (2 inches) wide than small insects etc. The outer barrel is grooved to accept Canon's MR-14 [[ring flash]] which can be used as the principal light source for close-ups or as on-axis [[Fill light|fill lighting]] for portraits. The six-blade [[Diaphragm (optics)|diaphragm]] provides reasonably good out-of-focus blur ([[bokeh]]) for portrait work.

First introduced in 1987, it is the oldest lens in Canon's current lineup ({{as of|2014|1|lc=on}}) that is still available new.<ref>{{cite web |url=http://www.the-digital-picture.com/News/News-Post.aspx?News=8777 |title=What are the 10 Oldest Canon Lenses Currently Available? |first=Bryan |last=Carnathan |publisher=The-Digital-Picture.com |date=January 9, 2014 |accessdate=January 10, 2014}}</ref> The lens is constructed with a plastic body and metal mount, and features a distance window with infrared index and magnification markings. The optional '''Life-Size Converter EF'''<ref name="canonusa1">{{cite web|url=http://www.usa.canon.com/consumer/controller?act=ModelInfoAct&fcategoryid=155&modelid=8121|title=Life-Size Converter EF|work=Canon USA|author=[[Canon Inc.]]|accessdate=2007-10-15}}</ref> adapts the lens to produce a maximum magnification of 1:1. Attaching the converter increases the lens focal length to 70mm, reduces the maximum aperture to {{f/}}3.5 and limits the focal range. Magnification markings for the converter are shown on the (extending) inner lens barrel.

[[File:Canon EF 50mm II lens front and rear side-by-side version3.JPG|thumb|Rear-up (left) and front-up (right) views of a Canon EF 50mm f/1.8 II [[prime lens]]]]
The '''EF 50mm lenses''' are a group of [[normal lens|normal]] [[prime lens|prime]] [[photographic lens|lenses]] made by [[Canon (company)|Canon]] that share the same [[focal length]]. These lenses are based on the classic [[double-Gauss lens]],<ref>http://www.canon.com/camera-museum/camera/lens/ef/data/standard/ef_50_18ii.html?p=1 {{dead link|date=March 2015}}</ref> with the f/1.8 being a standard six-element double-Gauss with an air gap and powers between element 2 and 3<ref>[http://www.canon.com/camera-museum/camera/lens/ef/data/standard/ef_50_18ii.html?p=2] {{dead link|date=March 2015}}</ref> and its [[Lens speed|faster]] cousins adding additional elements.<ref>[http://www.canon.com/camera-museum/camera/lens/ef/standard.html] {{dead link|date=March 2015}}</ref> The 50mm focal length, when used with a 35mm film or full-frame sensor, has been widely considered to match the perspective seen by the human eye.<ref>[http://www.vothphoto.com/spotlight/articles/forgotten_lens/forgotten-lens.htm 50mm and the Human Eye], ''Gary Voth''. Retrieved 2011-01-10.</ref>

Canon 50mm lenses have an [[Canon EF lens mount|EF]] type mount that fits the Canon [[Canon EOS|EOS]] line of cameras. When pairing a 50mm lens to a Canon DSLR with an [[APS-C]] sized sensor, the [[crop factor]] effectively turns the 50mm focal length into a 80mm field of view.

Six EF 50mm lenses have been sold by Canon:

==EF 50mm {{f/}}1.0L USM==
The discontinued '''EF 50mm {{f/}}1.0L [[Ultrasonic motor|USM]]''' is a professional L series autofocus lens. On the used market sells for as much as double the original retail value.{{fact|date=October 2008}} It was the fastest [[Single Lens Reflex|SLR]] lens in production during its lifetime.<ref name="canonmuseum_ef50f10l"/> This lens has a metal body and mount, and plastic extremities. It also features a wide rubber focus ring that is [[Damping|damped]], a distance window with [[Infrared photography|infrared]] index, and the ability to set the focus range from 0.6m to infinity, or 1m to infinity. In common with the [[Canon EF 85mm lens|EF 85mm f/1.2L USM]] it uses an electronic "focus by wire" system and requires power from the camera in order to manual focus. The 8-blade diaphragm and maximum [[aperture]] of {{f/}}1.0 give this lens the ability to create extremely shallow [[depth of field]] effects and to support low light situations. The optical construction of this lens contains 11 lens elements, including two ground and polished [[Aspheric lens|aspherical lens]] elements. This lens uses a floating front extension [[Focus (optics)|focusing]] system, powered by a ring-type USM motor. The front of the lens does not rotate, but does extend when focusing.

Despite its price and large maximum aperture, the 1.0L was not a particularly sharp lens at any aperture, and the two cheaper 50mm options offered far better sharpness when stopped down beyond about {{f/}}2.8.<ref>{{cite web|url=http://www.wlcastleman.com/equip/reviews/50mm/index.htm|title=Review of the Canon EF 50mm f/1.0L USM Lens, EF 50mm f/1.4 USM lens,
and EF 50mm f/1.8 II Lens|work=wlcastleman.com}}</ref> This, combined with the high production cost and low sales volume, led to it being discontinued in 2000 and eventually superseded by the {{f/}}1.2 edition.

==EF 50mm {{f/}}1.2L USM==
The '''EF 50mm {{f/}}1.2L [[Ultrasonic motor|USM]]''' is a professional L series lens designed to replace the '''EF 50mm {{f/}}1.0L USM'''. It is constructed with a metal body and mount, and plastic extremities. This lens features a wide rubber focusing ring that is damped, a distance window with infrared index, and is fully weather-sealed, when a filter is added to the front. A circular, 8-blade diaphragm and maximum aperture of {{f/}}1.2 give this lens the ability to create very shallow depth of field effects with smooth background blur. The optical construction of this lens contains 8 lens elements, including one ground and polished aspherical lens element. This lens uses a floating front extension focusing system, powered by a ring-type USM motor. The front of the lens does not rotate or extend when focusing.

==EF 50mm {{f/}}1.4 USM==
[[File:Canon EF 50mm f1.4.jpg|thumb|EF 50mm f/1.4 USM, showing its large maximum aperture; at {{f/}}1.4 and 50 mm, the [[entrance pupil]] diameter is 35.7 mm.]]
The '''EF 50mm {{f/}}1.4 USM''' is a consumer- and professional-level lens. It is the least expensive {{f/}}1.4 aperture lens that Canon currently manufactures. It is constructed with a plastic body and a metal mount. This lens features a distance window with infrared index. An 8-blade diaphragm and maximum aperture of {{f/}}1.4 give this lens the ability to create shallow depth of field effects. The optical construction of this lens contains 7 lens elements including 2 high refraction elements, but no aspherical, high dispersion or [[calcium fluoride]] elements. The lens uses a front extension focusing system, powered by a micro [[Ultrasonic motor|USM]] motor. Even though this lens uses a micro USM motor, it still has FTM (full-time manual focus) available. Auto-focus speed of this lens is fast, but not as quick as most ring-USM-based lenses. The front of the lens does not rotate, but extends by up to about one centimeter when focusing.
{{-}}

==EF 50mm {{f/}}1.8==
The '''EF 50mm {{f/}}1.8''' is an economy level lens (discontinued in 1990), which has been replaced by the '''EF 50mm {{f/}}1.8 II'''. The body is plastic but the lens mount is metal, and it features a distance window with infrared index. A 5 blade maximum aperture of {{f/}}1.8 gives this lens the ability to create depth of field effects.

The optical construction of this lens contains 6 lens elements, with no special elements. This lens uses a front extension focusing system, powered by an AFD motor. The front of the lens does not rotate when focusing, making it compatible with circular polarisers.

Although auto-focus speed, despite the AFD motor, is moderately fast but audible, the lens is still very popular.

Because of its low price (it is sold used only) and very sharp optical quality, this lens has earned the preference of a lot of photographers. Obviously, when shooting at f/1.8, it offers a very shallow depth of field which is beneficial for isolating subjects against a blurred background (bokeh).

[[File:Canon EF 50 mm f 1.8 II.jpg|thumb|The EF 50mm f/1.8 II]]
The '''EF 50mm {{f/}}1.8 II''' replaced the '''EF 50mm {{f/}}1.8''' in 1991. The '''EF 50mm {{f/}}1.8 II''' has lost the metal lens mount, the distance scale, the IR focusing label and the separate manual focusing ring that came with the original '''EF 50mm {{f/}}1.8'''.

The current '''EF 50mm {{f/}}1.8 II''' lens has a plastic lens mount. The manual focusing ring has been replaced by a very small thin focusing ring on the front tip of the lens. However the lens does not suffer from rotating front lens element and can be used with [[Polarizing filter (photography)|polarizing filters]]. The optics for both lenses are identical, with 6 elements in 5 groups and a 5 blade diaphragm. Nevertheless, some photographers think the original '''EF 50mm {{f/}}1.8''' is slightly better {{Dubious|date=May 2014}} {{Citation needed|date=May 2014}}. Both lenses have a 52mm filter thread.

Because of its low price and sharp optical quality, this lens has earned the nicknames 'nifty fifty' and 'plastic fantastic'. When shooting at f/1.8, it offers a very shallow [[depth of field]] which is beneficial for isolating subjects against a blurred background ([[bokeh]]).

==EF 50mm {{f/}}1.8 STM==
Canon introduced the EF 50mm {{f/}}1.8 STM on May 10, 2015. This lens utilizes Canon's STM focusing motor, which supports the Movie Servo autofocus mode. The lens features a metal mount and has a rounded seven-blade aperture.<ref>{{cite web|url=http://www.usa.canon.com/cusa/about_canon/newsroom?pageKeyCode=pressreldetail&docId=0901e02480f0929b|title=

The '''EF 50mm f/2.5 Compact Macro''' is a relatively inexpensive [[Macro photography|macro]] lens with a minimum focusing distance of 23cm (9 inches) offering a maximum magnification of 0.5x actual size.<ref name="canonmuseum_ef50f25" /> Reviewers describe the lens as having "decent"/"mid-level" build quality, with very good color and contrast, "absolutely negligible" distortion, very sharp after f/4 and peak performance at f/5.6. However, auto-focusing is relatively slow and noisy.<ref>{{cite web |title=Canon EF 50mm f/2.5 macro - Review / Test Report - Analysis |url=http://www.photozone.de/canon-eos/161-canon-ef-50mm-f25-macro-test-report--review?start=1 |publisher=Photozone |accessdate=2010-06-18 }}</ref><ref>{{cite web |title=Canon EF 50mm f/2.5 Macro Lens Review |first=Bryan |last=Carnathan |publisher=The-Digital-Picture.com |url=http://www.the-digital-picture.com/Reviews/Canon-EF-50mm-f-2.5-Compact-Macro-Lens-Review.aspx |accessdate=2010-06-18}}</ref>

The maximum 0.5x magnification means this lens is more suitable for photographing documents, products and objects at least 5cm (2 inches) wide than small insects etc. The outer barrel is grooved to accept Canon's MR-14 [[ring flash]] which can be used as the principal light source for close-ups or as on-axis [[Fill light|fill lighting]] for portraits. The six-blade [[Diaphragm (optics)|diaphragm]] provides reasonably good out-of-focus blur ([[bokeh]]) for portrait work.

First introduced in 1987, it is the oldest lens in Canon's current lineup ({{as of|2014|1|lc=on}}) that is still available new.<ref>{{cite web |url=http://www.the-digital-picture.com/News/News-Post.aspx?News=8777 |title=What are the 10 Oldest Canon Lenses Currently Available? |first=Bryan |last=Carnathan |publisher=The-Digital-Picture.com |date=January 9, 2014 |accessdate=January 10, 2014}}</ref> The lens is constructed with a plastic body and metal mount, and features a distance window with infrared index and magnification markings. The optional '''Life-Size Converter EF'''<ref name="canonusa1">{{cite web|url=http://www.usa.canon.com/consumer/controller?act=ModelInfoAct&fcategoryid=155&modelid=8121|title=Life-Size Converter EF|work=Canon USA|author=[[Canon Inc.]]|accessdate=2007-10-15}}</ref> adapts the lens to produce a maximum magnification of 1:1. Attaching the converter increases the lens focal length to 70mm, reduces the maximum aperture to {{f/}}3.5 and limits the focal range. Magnification markings for the converter are shown on the (extending) inner lens barrel.

Geognerd: /* Specifications */ Added EF 50mm f/1.8 STM

[[File:Canon EF 50mm II lens front and rear side-by-side version3.JPG|thumb|Rear-up (left) and front-up (right) views of a Canon EF 50mm f/1.8 II [[prime lens]]]]
The '''EF 50mm lenses''' are a group of [[normal lens|normal]] [[prime lens|prime]] [[photographic lens|lenses]] made by [[Canon (company)|Canon]] that share the same [[focal length]]. These lenses are based on the classic [[double-Gauss lens]],<ref>http://www.canon.com/camera-museum/camera/lens/ef/data/standard/ef_50_18ii.html?p=1 {{dead link|date=March 2015}}</ref> with the f/1.8 being a standard six-element double-Gauss with an air gap and powers between element 2 and 3<ref>[http://www.canon.com/camera-museum/camera/lens/ef/data/standard/ef_50_18ii.html?p=2] {{dead link|date=March 2015}}</ref> and its [[Lens speed|faster]] cousins adding additional elements.<ref>[http://www.canon.com/camera-museum/camera/lens/ef/standard.html] {{dead link|date=March 2015}}</ref> The 50mm focal length, when used with a 35mm film or full-frame sensor, has been widely considered to match the perspective seen by the human eye.<ref>[http://www.vothphoto.com/spotlight/articles/forgotten_lens/forgotten-lens.htm 50mm and the Human Eye], ''Gary Voth''. Retrieved 2011-01-10.</ref>

Canon 50mm lenses have an [[Canon EF lens mount|EF]] type mount that fits the Canon [[Canon EOS|EOS]] line of cameras. When pairing a 50mm lens to a Canon DSLR with an [[APS-C]] sized sensor, the [[crop factor]] effectively turns the 50mm focal length into a 80mm field of view.

Six EF 50mm lenses have been sold by Canon:

==EF 50mm {{f/}}1.0L USM==
The discontinued '''EF 50mm {{f/}}1.0L [[Ultrasonic motor|USM]]''' is a professional L series autofocus lens. On the used market sells for as much as double the original retail value.{{fact|date=October 2008}} It was the fastest [[Single Lens Reflex|SLR]] lens in production during its lifetime.<ref name="canonmuseum_ef50f10l"/> This lens has a metal body and mount, and plastic extremities. It also features a wide rubber focus ring that is [[Damping|damped]], a distance window with [[Infrared photography|infrared]] index, and the ability to set the focus range from 0.6m to infinity, or 1m to infinity. In common with the [[Canon EF 85mm lens|EF 85mm f/1.2L USM]] it uses an electronic "focus by wire" system and requires power from the camera in order to manual focus. The 8-blade diaphragm and maximum [[aperture]] of {{f/}}1.0 give this lens the ability to create extremely shallow [[depth of field]] effects and to support low light situations. The optical construction of this lens contains 11 lens elements, including two ground and polished [[Aspheric lens|aspherical lens]] elements. This lens uses a floating front extension [[Focus (optics)|focusing]] system, powered by a ring-type USM motor. The front of the lens does not rotate, but does extend when focusing.

Despite its price and large maximum aperture, the 1.0L was not a particularly sharp lens at any aperture, and the two cheaper 50mm options offered far better sharpness when stopped down beyond about {{f/}}2.8.<ref>{{cite web|url=http://www.wlcastleman.com/equip/reviews/50mm/index.htm|title=Review of the Canon EF 50mm f/1.0L USM Lens, EF 50mm f/1.4 USM lens,
and EF 50mm f/1.8 II Lens|work=wlcastleman.com}}</ref> This, combined with the high production cost and low sales volume, led to it being discontinued in 2000 and eventually superseded by the {{f/}}1.2 edition.

==EF 50mm {{f/}}1.2L USM==
The '''EF 50mm {{f/}}1.2L [[Ultrasonic motor|USM]]''' is a professional L series lens designed to replace the '''EF 50mm {{f/}}1.0L USM'''. It is constructed with a metal body and mount, and plastic extremities. This lens features a wide rubber focusing ring that is damped, a distance window with infrared index, and is fully weather-sealed, when a filter is added to the front. A circular, 8-blade diaphragm and maximum aperture of {{f/}}1.2 give this lens the ability to create very shallow depth of field effects with smooth background blur. The optical construction of this lens contains 8 lens elements, including one ground and polished aspherical lens element. This lens uses a floating front extension focusing system, powered by a ring-type USM motor. The front of the lens does not rotate or extend when focusing.

==EF 50mm {{f/}}1.4 USM==
[[File:Canon EF 50mm f1.4.jpg|thumb|EF 50mm f/1.4 USM, showing its large maximum aperture; at {{f/}}1.4 and 50 mm, the [[entrance pupil]] diameter is 35.7 mm.]]
The '''EF 50mm {{f/}}1.4 USM''' is a consumer- and professional-level lens. It is the least expensive {{f/}}1.4 aperture lens that Canon currently manufactures. It is constructed with a plastic body and a metal mount. This lens features a distance window with infrared index. An 8-blade diaphragm and maximum aperture of {{f/}}1.4 give this lens the ability to create shallow depth of field effects. The optical construction of this lens contains 7 lens elements including 2 high refraction elements, but no aspherical, high dispersion or [[calcium fluoride]] elements. The lens uses a front extension focusing system, powered by a micro [[Ultrasonic motor|USM]] motor. Even though this lens uses a micro USM motor, it still has FTM (full-time manual focus) available. Auto-focus speed of this lens is fast, but not as quick as most ring-USM-based lenses. The front of the lens does not rotate, but extends by up to about one centimeter when focusing.
{{-}}

==EF 50mm {{f/}}1.8==
The '''EF 50mm {{f/}}1.8''' is an economy level lens (discontinued in 1990), which has been replaced by the '''EF 50mm {{f/}}1.8 II'''. The body is plastic but the lens mount is metal, and it features a distance window with infrared index. A 5 blade maximum aperture of {{f/}}1.8 gives this lens the ability to create depth of field effects.

The optical construction of this lens contains 6 lens elements, with no special elements. This lens uses a front extension focusing system, powered by an AFD motor. The front of the lens does not rotate when focusing, making it compatible with circular polarisers.

Although auto-focus speed, despite the AFD motor, is moderately fast but audible, the lens is still very popular.

Because of its low price (it is sold used only) and very sharp optical quality, this lens has earned the preference of a lot of photographers. Obviously, when shooting at f/1.8, it offers a very shallow depth of field which is beneficial for isolating subjects against a blurred background (bokeh).

==EF 50mm {{f/}}1.8 II==
[[File:Brahma-at-wat-chedi-liam-wiang-kum-kam-chiang-mai-thailand.jpg|thumb|left|Black and white image taken with EF 50mm f/1.8 II demonstrating depth of field at f/6.3 ([/media/wikipedia/commons/4/4f/Brahma-at-wat-chedi-liam-wiang-kum-kam-chiang-mai-thailand.jpg view at full size])]]
[[File:Canon EF 50 mm f 1.8 II.jpg|thumb|The EF 50mm f/1.8 II]]
The '''EF 50mm {{f/}}1.8 II''' replaced the '''EF 50mm {{f/}}1.8''' in 1991. The '''EF 50mm {{f/}}1.8 II''' has lost the metal lens mount, the distance scale, the IR focusing label and the separate manual focusing ring that came with the original '''EF 50mm {{f/}}1.8'''.

The current '''EF 50mm {{f/}}1.8 II''' lens has a plastic lens mount. The manual focusing ring has been replaced by a very small thin focusing ring on the front tip of the lens. However the lens does not suffer from rotating front lens element and can be used with [[Polarizing filter (photography)|polarizing filters]]. The optics for both lenses are identical, with 6 elements in 5 groups and a 5 blade diaphragm. Nevertheless, some photographers think the original '''EF 50mm {{f/}}1.8''' is slightly better {{Dubious|date=May 2014}} {{Citation needed|date=May 2014}}. Both lenses have a 52mm filter thread.

Because of its low price and sharp optical quality, this lens has earned the nicknames 'nifty fifty' and 'plastic fantastic'. When shooting at f/1.8, it offers a very shallow [[depth of field]] which is beneficial for isolating subjects against a blurred background ([[bokeh]]).

==EF 50mm {{f/}}1.8 STM==
Canon introduced the EF 50mm {{f/}}1.8 STM on May 10, 2015. This lens utilizes Canon's STM focusing motor, which supports the Movie Servo autofocus mode. The lens features a metal mount and has a rounded seven-blade aperture.<ref>{{cite web|url=http://www.usa.canon.com/cusa/about_canon/newsroom?pageKeyCode=pressreldetail&docId=0901e02480f0929b|title=

[[Image:Canon LIFE-SIZE Converter.jpg|thumb|right|upright|Canon LIFE-SIZE Converter for the EF 50mm f/2.5 Compact Macro to get a magnification up to 1:1]]
The '''EF 50mm f/2.5 Compact Macro''' is a relatively inexpensive [[Macro photography|macro]] lens with a minimum focusing distance of 23cm (9 inches) offering a maximum magnification of 0.5x actual size.<ref name="canonmuseum_ef50f25" /> Reviewers describe the lens as having "decent"/"mid-level" build quality, with very good color and contrast, "absolutely negligible" distortion, very sharp after f/4 and peak performance at f/5.6. However, auto-focusing is relatively slow and noisy.<ref>{{cite web |title=Canon EF 50mm f/2.5 macro - Review / Test Report - Analysis |url=http://www.photozone.de/canon-eos/161-canon-ef-50mm-f25-macro-test-report--review?start=1 |publisher=Photozone |accessdate=2010-06-18 }}</ref><ref>{{cite web |title=Canon EF 50mm f/2.5 Macro Lens Review |first=Bryan |last=Carnathan |publisher=The-Digital-Picture.com |url=http://www.the-digital-picture.com/Reviews/Canon-EF-50mm-f-2.5-Compact-Macro-Lens-Review.aspx |accessdate=2010-06-18}}</ref>

The maximum 0.5x magnification means this lens is more suitable for photographing documents, products and objects at least 5cm (2 inches) wide than small insects etc. The outer barrel is grooved to accept Canon's MR-14 [[ring flash]] which can be used as the principal light source for close-ups or as on-axis [[Fill light|fill lighting]] for portraits. The six-blade [[Diaphragm (optics)|diaphragm]] provides reasonably good out-of-focus blur ([[bokeh]]) for portrait work.

First introduced in 1987, it is the oldest lens in Canon's current lineup ({{as of|2014|1|lc=on}}) that is still available new.<ref>{{cite web |url=http://www.the-digital-picture.com/News/News-Post.aspx?News=8777 |title=What are the 10 Oldest Canon Lenses Currently Available? |first=Bryan |last=Carnathan |publisher=The-Digital-Picture.com |date=January 9, 2014 |accessdate=January 10, 2014}}</ref> The lens is constructed with a plastic body and metal mount, and features a distance window with infrared index and magnification markings. The optional '''Life-Size Converter EF'''<ref name="canonusa1">{{cite web|url=http://www.usa.canon.com/consumer/controller?act=ModelInfoAct&fcategoryid=155&modelid=8121|title=Life-Size Converter EF|work=Canon USA|author=[[Canon Inc.]]|accessdate=2007-10-15}}</ref> adapts the lens to produce a maximum magnification of 1:1. Attaching the converter increases the lens focal length to 70mm, reduces the maximum aperture to {{f/}}3.5 and limits the focal range. Magnification markings for the converter are shown on the (extending) inner lens barrel.

[[File:Canon EF 50mm II lens front and rear side-by-side version3.JPG|thumb|Rear-up (left) and front-up (right) views of a Canon EF 50mm f/1.8 II [[prime lens]]]]
The '''EF 50mm lenses''' are a group of [[normal lens|normal]] [[prime lens|prime]] [[photographic lens|lenses]] made by [[Canon (company)|Canon]] that share the same [[focal length]]. These lenses are based on the classic [[double-Gauss lens]],<ref>http://www.canon.com/camera-museum/camera/lens/ef/data/standard/ef_50_18ii.html?p=1 {{dead link|date=March 2015}}</ref> with the f/1.8 being a standard six-element double-Gauss with an air gap and powers between element 2 and 3<ref>[http://www.canon.com/camera-museum/camera/lens/ef/data/standard/ef_50_18ii.html?p=2] {{dead link|date=March 2015}}</ref> and its [[Lens speed|faster]] cousins adding additional elements.<ref>[http://www.canon.com/camera-museum/camera/lens/ef/standard.html] {{dead link|date=March 2015}}</ref> The 50mm focal length, when used with a 35mm film or full-frame sensor, has been widely considered to match the perspective seen by the human eye.<ref>[http://www.vothphoto.com/spotlight/articles/forgotten_lens/forgotten-lens.htm 50mm and the Human Eye], ''Gary Voth''. Retrieved 2011-01-10.</ref>

Canon 50mm lenses have an [[Canon EF lens mount|EF]] type mount that fits the Canon [[Canon EOS|EOS]] line of cameras. When pairing a 50mm lens to a Canon DSLR with an [[APS-C]] sized sensor, the [[crop factor]] effectively turns the 50mm focal length into a 80mm field of view.

Six EF 50mm lenses have been sold by Canon:

==EF 50mm {{f/}}1.0L USM==
The discontinued '''EF 50mm {{f/}}1.0L [[Ultrasonic motor|USM]]''' is a professional L series autofocus lens. On the used market sells for as much as double the original retail value.{{fact|date=October 2008}} It was the fastest [[Single Lens Reflex|SLR]] lens in production during its lifetime.<ref name="canonmuseum_ef50f10l"/> This lens has a metal body and mount, and plastic extremities. It also features a wide rubber focus ring that is [[Damping|damped]], a distance window with [[Infrared photography|infrared]] index, and the ability to set the focus range from 0.6m to infinity, or 1m to infinity. In common with the [[Canon EF 85mm lens|EF 85mm f/1.2L USM]] it uses an electronic "focus by wire" system and requires power from the camera in order to manual focus. The 8-blade diaphragm and maximum [[aperture]] of {{f/}}1.0 give this lens the ability to create extremely shallow [[depth of field]] effects and to support low light situations. The optical construction of this lens contains 11 lens elements, including two ground and polished [[Aspheric lens|aspherical lens]] elements. This lens uses a floating front extension [[Focus (optics)|focusing]] system, powered by a ring-type USM motor. The front of the lens does not rotate, but does extend when focusing.

Despite its price and large maximum aperture, the 1.0L was not a particularly sharp lens at any aperture, and the two cheaper 50mm options offered far better sharpness when stopped down beyond about {{f/}}2.8.<ref>{{cite web|url=http://www.wlcastleman.com/equip/reviews/50mm/index.htm|title=Review of the Canon EF 50mm f/1.0L USM Lens, EF 50mm f/1.4 USM lens,
and EF 50mm f/1.8 II Lens|work=wlcastleman.com}}</ref> This, combined with the high production cost and low sales volume, led to it being discontinued in 2000 and eventually superseded by the {{f/}}1.2 edition.

==EF 50mm {{f/}}1.2L USM==
The '''EF 50mm {{f/}}1.2L [[Ultrasonic motor|USM]]''' is a professional L series lens designed to replace the '''EF 50mm {{f/}}1.0L USM'''. It is constructed with a metal body and mount, and plastic extremities. This lens features a wide rubber focusing ring that is damped, a distance window with infrared index, and is fully weather-sealed, when a filter is added to the front. A circular, 8-blade diaphragm and maximum aperture of {{f/}}1.2 give this lens the ability to create very shallow depth of field effects with smooth background blur. The optical construction of this lens contains 8 lens elements, including one ground and polished aspherical lens element. This lens uses a floating front extension focusing system, powered by a ring-type USM motor. The front of the lens does not rotate or extend when focusing.

==EF 50mm {{f/}}1.4 USM==
[[File:Canon EF 50mm f1.4.jpg|thumb|EF 50mm f/1.4 USM, showing its large maximum aperture; at {{f/}}1.4 and 50 mm, the [[entrance pupil]] diameter is 35.7 mm.]]
The '''EF 50mm {{f/}}1.4 USM''' is a consumer- and professional-level lens. It is the least expensive {{f/}}1.4 aperture lens that Canon currently manufactures. It is constructed with a plastic body and a metal mount. This lens features a distance window with infrared index. An 8-blade diaphragm and maximum aperture of {{f/}}1.4 give this lens the ability to create shallow depth of field effects. The optical construction of this lens contains 7 lens elements including 2 high refraction elements, but no aspherical, high dispersion or [[calcium fluoride]] elements. The lens uses a front extension focusing system, powered by a micro [[Ultrasonic motor|USM]] motor. Even though this lens uses a micro USM motor, it still has FTM (full-time manual focus) available. Auto-focus speed of this lens is fast, but not as quick as most ring-USM-based lenses. The front of the lens does not rotate, but extends by up to about one centimeter when focusing.
{{-}}

==EF 50mm {{f/}}1.8==
The '''EF 50mm {{f/}}1.8''' is an economy level lens (discontinued in 1990), which has been replaced by the '''EF 50mm {{f/}}1.8 II'''. The body is plastic but the lens mount is metal, and it features a distance window with infrared index. A 5 blade maximum aperture of {{f/}}1.8 gives this lens the ability to create depth of field effects.

The optical construction of this lens contains 6 lens elements, with no special elements. This lens uses a front extension focusing system, powered by an AFD motor. The front of the lens does not rotate when focusing, making it compatible with circular polarisers.

Although auto-focus speed, despite the AFD motor, is moderately fast but audible, the lens is still very popular.

Because of its low price (it is sold used only) and very sharp optical quality, this lens has earned the preference of a lot of photographers. Obviously, when shooting at f/1.8, it offers a very shallow depth of field which is beneficial for isolating subjects against a blurred background (bokeh).

==EF 50mm {{f/}}1.8 II==
[[File:Brahma-at-wat-chedi-liam-wiang-kum-kam-chiang-mai-thailand.jpg|thumb|left|Black and white image taken with EF 50mm f/1.8 II demonstrating depth of field at f/6.3 ([/media/wikipedia/commons/4/4f/Brahma-at-wat-chedi-liam-wiang-kum-kam-chiang-mai-thailand.jpg view at full size])]]
[[File:Canon EF 50 mm f 1.8 II.jpg|thumb|The EF 50mm f/1.8 II]]
The '''EF 50mm {{f/}}1.8 II''' replaced the '''EF 50mm {{f/}}1.8''' in 1991. The '''EF 50mm {{f/}}1.8 II''' has lost the metal lens mount, the distance scale, the IR focusing label and the separate manual focusing ring that came with the original '''EF 50mm {{f/}}1.8'''.

The current '''EF 50mm {{f/}}1.8 II''' lens has a plastic lens mount. The manual focusing ring has been replaced by a very small thin focusing ring on the front tip of the lens. However the lens does not suffer from rotating front lens element and can be used with [[Polarizing filter (photography)|polarizing filters]]. The optics for both lenses are identical, with 6 elements in 5 groups and a 5 blade diaphragm. Nevertheless, some photographers think the original '''EF 50mm {{f/}}1.8''' is slightly better {{Dubious|date=May 2014}} {{Citation needed|date=May 2014}}. Both lenses have a 52mm filter thread.

Because of its low price and sharp optical quality, this lens has earned the nicknames 'nifty fifty' and 'plastic fantastic'. When shooting at f/1.8, it offers a very shallow [[depth of field]] which is beneficial for isolating subjects against a blurred background ([[bokeh]]).

==EF 50mm {{f/}}1.8 STM==
Canon introduced the EF 50mm {{f/}}1.8 STM on May 10, 2015. This lens utilizes Canon's STM focusing motor, which supports the Movie Servo autofocus mode. The lens features a metal mount and has a rounded seven-blade aperture.<ref>{{cite web|url=http://www.usa.canon.com/cusa/about_canon/newsroom?pageKeyCode=pressreldetail&docId=0901e02480f0929b|title=

==EF 50mm {{f/}}2.5 Compact Macro==
[[Image:Damsel fly cropped - Canon 50mm compact macro.jpg|thumb|left|Close-up taken with 50mm Compact Macro]]
[[Image:Canon EF 50mm Compact Macro extended.jpg|thumb|right|upright|Canon EF 50mm compact macro with inner lens barrel extended]]
[[Image:Canon LIFE-SIZE Converter.jpg|thumb|right|upright|Canon LIFE-SIZE Converter for the EF 50mm f/2.5 Compact Macro to get a magnification up to 1:1]]
The '''EF 50mm f/2.5 Compact Macro''' is a relatively inexpensive [[Macro photography|macro]] lens with a minimum focusing distance of 23cm (9 inches) offering a maximum magnification of 0.5x actual size.<ref name="canonmuseum_ef50f25" /> Reviewers describe the lens as having "decent"/"mid-level" build quality, with very good color and contrast, "absolutely negligible" distortion, very sharp after f/4 and peak performance at f/5.6. However, auto-focusing is relatively slow and noisy.<ref>{{cite web |title=Canon EF 50mm f/2.5 macro - Review / Test Report - Analysis |url=http://www.photozone.de/canon-eos/161-canon-ef-50mm-f25-macro-test-report--review?start=1 |publisher=Photozone |accessdate=2010-06-18 }}</ref><ref>{{cite web |title=Canon EF 50mm f/2.5 Macro Lens Review |first=Bryan |last=Carnathan |publisher=The-Digital-Picture.com |url=http://www.the-digital-picture.com/Reviews/Canon-EF-50mm-f-2.5-Compact-Macro-Lens-Review.aspx |accessdate=2010-06-18}}</ref>

The maximum 0.5x magnification means this lens is more suitable for photographing documents, products and objects at least 5cm (2 inches) wide than small insects etc. The outer barrel is grooved to accept Canon's MR-14 [[ring flash]] which can be used as the principal light source for close-ups or as on-axis [[Fill light|fill lighting]] for portraits. The six-blade [[Diaphragm (optics)|diaphragm]] provides reasonably good out-of-focus blur ([[bokeh]]) for portrait work.

First introduced in 1987, it is the oldest lens in Canon's current lineup ({{as of|2014|1|lc=on}}) that is still available new.<ref>{{cite web |url=http://www.the-digital-picture.com/News/News-Post.aspx?News=8777 |title=What are the 10 Oldest Canon Lenses Currently Available? |first=Bryan |last=Carnathan |publisher=The-Digital-Picture.com |date=January 9, 2014 |accessdate=January 10, 2014}}</ref> The lens is constructed with a plastic body and metal mount, and features a distance window with infrared index and magnification markings. The optional '''Life-Size Converter EF'''<ref name="canonusa1">{{cite web|url=http://www.usa.canon.com/consumer/controller?act=ModelInfoAct&fcategoryid=155&modelid=8121|title=Life-Size Converter EF|work=Canon USA|author=[[Canon Inc.]]|accessdate=2007-10-15}}</ref> adapts the lens to produce a maximum magnification of 1:1. Attaching the converter increases the lens focal length to 70mm, reduces the maximum aperture to {{f/}}3.5 and limits the focal range. Magnification markings for the converter are shown on the (extending) inner lens barrel.

The '''EF 50mm lenses''' are a group of [[normal lens|normal]] [[prime lens|prime]] [[photographic lens|lenses]] made by [[Canon (company)|Canon]] that share the same [[focal length]]. These lenses are based on the classic [[double-Gauss lens]],<ref>http://www.canon.com/camera-museum/camera/lens/ef/data/standard/ef_50_18ii.html?p=1 {{dead link|date=March 2015}}</ref> with the f/1.8 being a standard six-element double-Gauss with an air gap and powers between element 2 and 3<ref>[http://www.canon.com/camera-museum/camera/lens/ef/data/standard/ef_50_18ii.html?p=2] {{dead link|date=March 2015}}</ref> and its [[Lens speed|faster]] cousins adding additional elements.<ref>[http://www.canon.com/camera-museum/camera/lens/ef/standard.html] {{dead link|date=March 2015}}</ref> The 50mm focal length, when used with a 35mm film or full-frame sensor, has been widely considered to match the perspective seen by the human eye.<ref>[http://www.vothphoto.com/spotlight/articles/forgotten_lens/forgotten-lens.htm 50mm and the Human Eye], ''Gary Voth''. Retrieved 2011-01-10.</ref>

Canon 50mm lenses have an [[Canon EF lens mount|EF]] type mount that fits the Canon [[Canon EOS|EOS]] line of cameras. When pairing a 50mm lens to a Canon DSLR with an [[APS-C]] sized sensor, the [[crop factor]] effectively turns the 50mm focal length into a 80mm field of view.

Six EF 50mm lenses have been sold by Canon:

==EF 50mm {{f/}}1.0L USM==
The discontinued '''EF 50mm {{f/}}1.0L [[Ultrasonic motor|USM]]''' is a professional L series autofocus lens. On the used market sells for as much as double the original retail value.{{fact|date=October 2008}} It was the fastest [[Single Lens Reflex|SLR]] lens in production during its lifetime.<ref name="canonmuseum_ef50f10l"/> This lens has a metal body and mount, and plastic extremities. It also features a wide rubber focus ring that is [[Damping|damped]], a distance window with [[Infrared photography|infrared]] index, and the ability to set the focus range from 0.6m to infinity, or 1m to infinity. In common with the [[Canon EF 85mm lens|EF 85mm f/1.2L USM]] it uses an electronic "focus by wire" system and requires power from the camera in order to manual focus. The 8-blade diaphragm and maximum [[aperture]] of {{f/}}1.0 give this lens the ability to create extremely shallow [[depth of field]] effects and to support low light situations. The optical construction of this lens contains 11 lens elements, including two ground and polished [[Aspheric lens|aspherical lens]] elements. This lens uses a floating front extension [[Focus (optics)|focusing]] system, powered by a ring-type USM motor. The front of the lens does not rotate, but does extend when focusing.

Despite its price and large maximum aperture, the 1.0L was not a particularly sharp lens at any aperture, and the two cheaper 50mm options offered far better sharpness when stopped down beyond about {{f/}}2.8.<ref>{{cite web|url=http://www.wlcastleman.com/equip/reviews/50mm/index.htm|title=Review of the Canon EF 50mm f/1.0L USM Lens, EF 50mm f/1.4 USM lens,
and EF 50mm f/1.8 II Lens|work=wlcastleman.com}}</ref> This, combined with the high production cost and low sales volume, led to it being discontinued in 2000 and eventually superseded by the {{f/}}1.2 edition.

==EF 50mm {{f/}}1.2L USM==
The '''EF 50mm {{f/}}1.2L [[Ultrasonic motor|USM]]''' is a professional L series lens designed to replace the '''EF 50mm {{f/}}1.0L USM'''. It is constructed with a metal body and mount, and plastic extremities. This lens features a wide rubber focusing ring that is damped, a distance window with infrared index, and is fully weather-sealed, when a filter is added to the front. A circular, 8-blade diaphragm and maximum aperture of {{f/}}1.2 give this lens the ability to create very shallow depth of field effects with smooth background blur. The optical construction of this lens contains 8 lens elements, including one ground and polished aspherical lens element. This lens uses a floating front extension focusing system, powered by a ring-type USM motor. The front of the lens does not rotate or extend when focusing.

==EF 50mm {{f/}}1.4 USM==
[[File:Canon EF 50mm f1.4.jpg|thumb|EF 50mm f/1.4 USM, showing its large maximum aperture; at {{f/}}1.4 and 50 mm, the [[entrance pupil]] diameter is 35.7 mm.]]
The '''EF 50mm {{f/}}1.4 USM''' is a consumer- and professional-level lens. It is the least expensive {{f/}}1.4 aperture lens that Canon currently manufactures. It is constructed with a plastic body and a metal mount. This lens features a distance window with infrared index. An 8-blade diaphragm and maximum aperture of {{f/}}1.4 give this lens the ability to create shallow depth of field effects. The optical construction of this lens contains 7 lens elements including 2 high refraction elements, but no aspherical, high dispersion or [[calcium fluoride]] elements. The lens uses a front extension focusing system, powered by a micro [[Ultrasonic motor|USM]] motor. Even though this lens uses a micro USM motor, it still has FTM (full-time manual focus) available. Auto-focus speed of this lens is fast, but not as quick as most ring-USM-based lenses. The front of the lens does not rotate, but extends by up to about one centimeter when focusing.
{{-}}

==EF 50mm {{f/}}1.8==
The '''EF 50mm {{f/}}1.8''' is an economy level lens (discontinued in 1990), which has been replaced by the '''EF 50mm {{f/}}1.8 II'''. The body is plastic but the lens mount is metal, and it features a distance window with infrared index. A 5 blade maximum aperture of {{f/}}1.8 gives this lens the ability to create depth of field effects.

The optical construction of this lens contains 6 lens elements, with no special elements. This lens uses a front extension focusing system, powered by an AFD motor. The front of the lens does not rotate when focusing, making it compatible with circular polarisers.

Although auto-focus speed, despite the AFD motor, is moderately fast but audible, the lens is still very popular.

Because of its low price (it is sold used only) and very sharp optical quality, this lens has earned the preference of a lot of photographers. Obviously, when shooting at f/1.8, it offers a very shallow depth of field which is beneficial for isolating subjects against a blurred background (bokeh).

==EF 50mm {{f/}}1.8 II==
[[File:Brahma-at-wat-chedi-liam-wiang-kum-kam-chiang-mai-thailand.jpg|thumb|left|Black and white image taken with EF 50mm f/1.8 II demonstrating depth of field at f/6.3 ([/media/wikipedia/commons/4/4f/Brahma-at-wat-chedi-liam-wiang-kum-kam-chiang-mai-thailand.jpg view at full size])]]
[[File:Canon EF 50 mm f 1.8 II.jpg|thumb|The EF 50mm f/1.8 II]]
The '''EF 50mm {{f/}}1.8 II''' replaced the '''EF 50mm {{f/}}1.8''' in 1991. The '''EF 50mm {{f/}}1.8 II''' has lost the metal lens mount, the distance scale, the IR focusing label and the separate manual focusing ring that came with the original '''EF 50mm {{f/}}1.8'''.

The current '''EF 50mm {{f/}}1.8 II''' lens has a plastic lens mount. The manual focusing ring has been replaced by a very small thin focusing ring on the front tip of the lens. However the lens does not suffer from rotating front lens element and can be used with [[Polarizing filter (photography)|polarizing filters]]. The optics for both lenses are identical, with 6 elements in 5 groups and a 5 blade diaphragm. Nevertheless, some photographers think the original '''EF 50mm {{f/}}1.8''' is slightly better {{Dubious|date=May 2014}} {{Citation needed|date=May 2014}}. Both lenses have a 52mm filter thread.

Because of its low price and sharp optical quality, this lens has earned the nicknames 'nifty fifty' and 'plastic fantastic'. When shooting at f/1.8, it offers a very shallow [[depth of field]] which is beneficial for isolating subjects against a blurred background ([[bokeh]]).

==EF 50mm {{f/}}1.8 STM==
Canon introduced the EF 50mm f/1.8 STM on May 10, 2015. This lens utilizes Canon's STM focusing motor, which supports the Movie Servo autofocus mode. The lens features a metal mount and has a rounded seven-blade aperture.

==EF 50mm {{f/}}2.5 Compact Macro==
[[Image:Damsel fly cropped - Canon 50mm compact macro.jpg|thumb|left|Close-up taken with 50mm Compact Macro]]
[[Image:Canon EF 50mm Compact Macro extended.jpg|thumb|right|upright|Canon EF 50mm compact macro with inner lens barrel extended]]
[[Image:Canon LIFE-SIZE Converter.jpg|thumb|right|upright|Canon LIFE-SIZE Converter for the EF 50mm f/2.5 Compact Macro to get a magnification up to 1:1]]
The '''EF 50mm f/2.5 Compact Macro''' is a relatively inexpensive [[Macro photography|macro]] lens with a minimum focusing distance of 23cm (9 inches) offering a maximum magnification of 0.5x actual size.<ref name="canonmuseum_ef50f25" /> Reviewers describe the lens as having "decent"/"mid-level" build quality, with very good color and contrast, "absolutely negligible" distortion, very sharp after f/4 and peak performance at f/5.6. However, auto-focusing is relatively slow and noisy.<ref>{{cite web |title=Canon EF 50mm f/2.5 macro - Review / Test Report - Analysis |url=http://www.photozone.de/canon-eos/161-canon-ef-50mm-f25-macro-test-report--review?start=1 |publisher=Photozone |accessdate=2010-06-18 }}</ref><ref>{{cite web |title=Canon EF 50mm f/2.5 Macro Lens Review |first=Bryan |last=Carnathan |publisher=The-Digital-Picture.com |url=http://www.the-digital-picture.com/Reviews/Canon-EF-50mm-f-2.5-Compact-Macro-Lens-Review.aspx |accessdate=2010-06-18}}</ref>

The maximum 0.5x magnification means this lens is more suitable for photographing documents, products and objects at least 5cm (2 inches) wide than small insects etc. The outer barrel is grooved to accept Canon's MR-14 [[ring flash]] which can be used as the principal light source for close-ups or as on-axis [[Fill light|fill lighting]] for portraits. The six-blade [[Diaphragm (optics)|diaphragm]] provides reasonably good out-of-focus blur ([[bokeh]]) for portrait work.

First introduced in 1987, it is the oldest lens in Canon's current lineup ({{as of|2014|1|lc=on}}) that is still available new.<ref>{{cite web |url=http://www.the-digital-picture.com/News/News-Post.aspx?News=8777 |title=What are the 10 Oldest Canon Lenses Currently Available? |first=Bryan |last=Carnathan |publisher=The-Digital-Picture.com |date=January 9, 2014 |accessdate=January 10, 2014}}</ref> The lens is constructed with a plastic body and metal mount, and features a distance window with infrared index and magnification markings. The optional '''Life-Size Converter EF'''<ref name="canonusa1">{{cite web|url=http://www.usa.canon.com/consumer/controller?act=ModelInfoAct&fcategoryid=155&modelid=8121|title=Life-Size Converter EF|work=Canon USA|author=[[Canon Inc.]]|accessdate=2007-10-15}}</ref> adapts the lens to produce a maximum magnification of 1:1. Attaching the converter increases the lens focal length to 70mm, reduces the maximum aperture to {{f/}}3.5 and limits the focal range. Magnification markings for the converter are shown on the (extending) inner lens barrel.

'''Roselle''' is a village located in both [[Cook County, Illinois|Cook County]] and [[DuPage County]], [[Illinois]]. Roselle is located in the northern edge of DuPage County 30 miles from downtown [[Chicago]]. The population was 23,115 at the 2000 census.

First incorporated in 1922, Roselle can correctly be categorized as a [[bedroom community]] — that is, a community that largely consists of residential zoning in both income streams and geographical area. Residents generally commute to Chicago or nearby suburbs for their jobs. As a result, the early rural atmosphere of the community has been lost over the past 30 years.

There are three main commercially-zoned areas in the village. One is along the southern border of the town along [[U.S. Highway 20|Lake Street]] (U.S. Route 20), the second is in the center of the village by the historical center of Park Street and [[Illinois State Route 19|Irving Park Road]] (Illinois Route 19). In [[2005]], a new downtown business development opened along the [[Soo Line]] railroad tracks just north of the town center (Main Street Station), the third is along Nerge Road the northern edge of the village. Plans are currently underway for the redevelopment of the Downtown District in addition to Main Street Staion, the several phase project is collectivley known as Village Crossing.

Bicycle trails link the nearby cities of [[Schaumburg, IL|Schaumburg]] and Bloomingdale. The [[North Central DuPage Regional Trail]] also runs through Roselle.

Roselle Music operated from 1959 to 2006 and produced some of the greatest musicians such as Ted Nugent, Billy Corgan and the Smashing Pumpkins.

== History ==
The area surrounding the current Village of Roselle began to be settled in the early 1830s, as settlers moved in next to the native [[Potawatomi|Potawatomi Indians]]. Silas L. Meacham and his brothers Harvey and Lyman settled the area now known as [[Bloomingdale Township, Illinois|Bloomingdale Township]]. The government had been offering land in the area for around $1.25 / acre. In [[1837]], Deacon Elijah Hough and his wife settled in the Bloomingdale area, with his sons Oramel, Rosell <nowiki>[sic]</nowiki> and daughter Cornelia.

In [[1868]], at the age of 48, Rosell Hough returned from a career as an alderman and a businessman in Chicago, and saw that the area had become a farming center for [[maize|corn]] and [[flax]]. He opened the Illinois Linen Company on the northwest corner off of what is now Roselle Road and [[Illinois Route 19|Irving Park Road]]. Hough was also the president of the Chicago and Pacific Railroad Company. It is rumored that because of his position, he spent some money to alter a land survey to show that a railroad line should run through Roselle, [[Itasca, Illinois|Itasca]] and [[Wood Dale, Illinois|Wood Dale]] instead of [[Addison, Illinois|Addison]] and [[Bloomingdale, Illinois|Bloomingdale]]. The new train schedule is believed to have misprinted the name of the new town on the new rail line, giving Roselle its current name.
