Canon EF 35mm lens
From Wikipedia, the free encyclopedia
The EF 35mm lenses are a group of wide angle prime lenses made by Canon Inc. that share the same focal length.
Focal lengths of 24mm to 35mm are considered wide angle. So the focal length of these lenses are at the long end of the wide angle range. The focal length of 35mm is close to the standard focal length of 50mm, but still retains a wider field of view. This focal length is used mostly for group portraits, landscapes, and for other general purposes. This makes these lenses popular for photographers who are new to wide angle, as it is not as restrictive as wider focal lengths.
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 56 mm lens mounted on a 35mm frame body. With a 1.3x body such as the Canon EOS-1D Mark III It provides a less narrower field of view, equivalent to an 46mm lens mounted on a 35mm frame body.
Two EF 35mm lenses are available. One of these is an L series lens.
- f/1.4L USM
- f/2

[edit] EF 35mm f/1.4L USM
The EF 35 mm f/1.4L USM is a professional L series lens. It is constructed with a metal body and mount, and with plastic extremities. Features of this lens are a wide rubber focus ring that is damped, and a distance window with infrared index. An 8 blade, maximum aperture of f/1.4, gives this lens the ability to create shallow depth of field effects. The optical construction of this lens contains 11 lens elements, including one ground and polished aspherical lens element. It uses a rear floating focusing system, powered by a ring type USM motor. Auto focus speed of this lens is very fast, and the front of the lens does not rotate, nor extend when focusing.
[edit] EF 35mm f/2
The EF 35 mm f/2 is a consumer level lens. It is constructed with a plastic body and a metal mount. This lens features a distance window with infrared index. A 5 blade, maximum aperture of f/2, gives this lens the ability to create depth of field effects, but not to the same narrowness of the EF 35 mm f/1.4L USM. The optical construction of this lens contains 7 lens elements, without any special lens elements. It uses a linear extension focusing system, that is powered by an AFD motor. Auto focus speed of this lens is moderately fast, but does make some sound. Front of the lens does not rotate when focusing, but does extend.
