The author was likely thinking of the 50mm f1.4 instead.). Sie kann sich erheblich von der aktuellen Version unterscheiden.

The EF 50mm lenses are a group of normal prime lenses made by Canon that share the same focal length.

These lenses have an EF type mount, that fits the Canon EOS line of cameras.

When used on a digital EOS body with a field of view compensation factor of 1.6x, such as the Canon EOS 400D, it provides a narrower field of view, equivalent to an 80mm lens mounted on a 35mm frame body. With a 1.3x body such as the Canon EOS-1D Mark III It provides a less narrow field of view, equivalent to an 65mm lens mounted on a 35mm frame body.

Six EF 50mm lenses have been developed and sold. Two of are L series lenses and three have Ultrasonic motors.

Since the Vorlage:F/1.2L, Vorlage:F/1.4 and Vorlage:F/1.8 lenses can provide very similar wide-aperture shots but have very different price tags, they have naturally been the subject of many in depth comparisons.

EF 50mm Vorlage:F/1.0L USM

The discontinued EF 50mm Vorlage:F/1.0L USM is a professional L series autofocus lens. It sells for as much as double the original retail value.Vorlage:Fact It is the fastest lens that Canon made for the EF mount, making this a collector's piece.Vorlage:Fact This lens has a metal body and mount, and plastic extremities. It also features a wide rubber focus ring that is damped, a distance window with infrared index, and the ability to set the focus range from 0.6m to infinity, or 1m to infinity. The 8-blades and maximum aperture of Vorlage:F/1.0 gives 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 aspherical lens elements. This lens uses a floating front extension focusing system, powered by a ring-type USM motor. The front of the lens does not rotate, but does extend when focusing.

EF 50mm Vorlage:F/1.2L USM

The EF 50mm Vorlage:F/1.2L USM is a professional L series lens, it was designed to replace the EF 50mm Vorlage:F/1.0L USM. It is the shorter of the only two Vorlage:F/1.2 lenses Canon makes, the other being the [[Canon EF 85mm lens|EF 85mm Vorlage:F//1.2L 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 weather-sealed. A circular, 8-blade, maximum aperture of Vorlage:F/1.2 gives this lens the ability to create very shallow depth of field effects. 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, but does extend when focusing.

EF 50mm Vorlage:F/1.4 USM

The EF 50mm Vorlage:F/1.4 USM is a consumer-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, maximum aperture of Vorlage:F/1.4 gives this lens the ability to create shallow depth of field effects. The optical construction of this lens contains 7 lens elements, without any special lens elements. This lens uses a front extension focusing system, powered by a micro 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 does extend when focusing.

EF 50mm Vorlage:F/1.8

The EF 50mm Vorlage:F/1.8 is an economy level lens (discontinued in 1990), which has been replaced by the EF 50mm Vorlage:F/1.8 II. It is constructed with a plastic body and a metal mount, and features a distance window with infrared index. A 5 blade maximum aperture of Vorlage: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, Front of the lens does not rotate when focusing, making it compatible with circular polarisers.

Auto focus speed, despite the AFD motor, is moderately fast although audible.

EF 50mm Vorlage:F/1.8 II

The EF 50mm Vorlage:F/1.8 II replaced the EF 50mm Vorlage:F/1.8 in 1991. Because of its low price but relatively high optical quality, this lens has excellent value. It is constructed with a plastic body and mount and has a very simple design.

Changes compared to the mk I model are the plastic mount, the absence of a distance window and a micro motor instead of an arc-form drive. Optically, this lens is almost identical to the first version.

The focus ring on this lens is even smaller than the one on the mk I model and placed on the front of the outer barrel.

EF 50mm Vorlage:F/2.5 Compact Macro

The EF 50mm Vorlage:F/2.5 Compact Macro is a consumer-level macro lens. It is constructed with a plastic body and metal mount. This lens features a distance window with infrared index, and magnification markings on the extending lens barrel. A 6-blade, maximum aperture of Vorlage:F/2.5 means this lens is not suited for depth of field effects, except at short focus distances. The optical construction of this lens contains 9 lens elements, without any special lens elements. This lens uses a front extension focusing system, powered by a micro motor. Auto focus speed of this lens is moderate, and does make sound. The front of the lens does not rotate when focusing, but it does extend considerably.

The EF 50mm Vorlage:F/2.5 Compact Macro can produce maximum magnification of 1:2, not the 1:1 of other Canon macro lenses. The optional Life-Size Converter EF[7] will allow this lens to produce a maximum magnification of 1:1. Attaching the converter costs the lens aperture size to Vorlage:F/3.5, as well as a reduced focus range. This converter is advertised as being proprietary to the EF 50mm Vorlage:F/2.5 Compact Macro. However, the converter can indeed be used with other lenses--in this case it focuses as both an extension tube and a 1.4x teleconverter.
