Front and rear views of a Canon EF50mm f/1.4 USM. The EF 50mm lenses are a group of normal prime lenses made by Canon that share the same focal length.These lenses are based on the classic double-Gauss lens, [1] with the f/1.8 being a standard six-element double-Gauss with an air gap and powers between element 2 and 3 [1] and its faster cousins adding additional elements. [2]
A fast prime (fixed focal length) lens, the Canon 50mm f / 1.4 (left), and a slower zoom lens, the Canon 18–55mm f / 3.5–5.6 (right); this lens is faster at 18mm than it is at 55mm. Lens speed is the maximum aperture diameter, or minimum f-number, of a photographic lens.
while shutter speeds in reciprocal seconds have a few conventional differences in their numbers (1 ⁄ 15, 1 ⁄ 30, and 1 ⁄ 60 second instead of 1 ⁄ 16, 1 ⁄ 32, and 1 ⁄ 64). In practice the maximum aperture of a lens is often not an integral power of √ 2 (i.e., √ 2 to the power of a whole number), in which case it is usually a half ...
The Canon Extender EF 1.4x II Image of the Canon 2x III Extender. The Canon Extender EF lenses are a group of teleconverter lenses made by Canon. These lenses are used between any compatible EF type lens and any of the Canon EOS line of cameras. When used with a compatible lens, they will multiply the focal length of the lens by a factor of ...
Canon FD 50 mm f /1.4 on AE-1 Program. Like its FL predecessor, the FD mount system allowed automatic diaphragm function, but in addition, a new signal pin supported full-aperture metering. A second signal pin for the "auto" setting of the aperture dial, plus a linkage to allow the camera to set the degree of diaphragm opening, enabled integral ...
The EF-M 32mm f/1.4 STM is an interchangeable prime lens introduced by Canon in September 2018. The lens is based on the EF-M mount that is used in Canon's lineup of mirrorless cameras. It currently is the latest lens published that uses the EF-M lens mount. With a maximum value of f/1.4, it has the largest aperture of all Canon EF-M mount lenses.
The "S" in EF-S has variously been described by Canon as coming from either "Small image circle" [1] (the lens projects a smaller image circle than normal EF lenses to match the sensor), or "Short back focus" [2] (the smaller mirror used in APS-C cameras also allows optical elements to protrude further into the camera body, reducing the minimum ...
With a 1.5× body such as the Nikon D300, it provides a less narrow field of view, equivalent to a 75 mm lens mounted on a 35 mm frame body. With a 1.3× body such as the Canon EOS-1D Mark III, it provides an even less narrow field of view, equivalent to a 65 mm lens mounted on a 35 mm frame body.
