and full-frame digital bodies. This focal length is commonly used for group portraits, landscapes, street photography, and general purpose photography, due to its relatively wide-angle views and low distortion characteristics. Four EF and one EF-S 35mm lenses have been developed. Two of these are L series lens. Three of the five lenses are currently available (the 1.4L II USM, the 2 IS USM and the EF-S 2.8 Macro IS STM). * 1.4L USM * 1.4L II USM * 2 * 2 IS USM * EF-S 2.8 Macro IS STM Due to the crop factor of Canon APS-C (1.6x) and APS-H (1.3x) sensors, all of the 35mm lenses have a equivalent focal length of 56mm and 45.5mm respectively.

EF 35mm 1.4L USM

The EF 35mm 1.4L USM is a professional L series lens. It is constructed with a metal body. Features of this lens are a wide rubber focus ring that is damped, and a distance window with infrared index. The maximum aperture of 1.4 gives this lens the ability to create shallow

system, powered by a ring type USM motor. Autofocus speed of this lens is very fast, and the front of the lens neither rotates nor extends when focusing.

EF 35mm 1.4L II USM

The EF 35mm 1.4L II USM is a successor of the EF 35mm 1.4L USM. It was announced at the 27th of August 2015 and is available since October same year. The EF 35mm 1.4L II USM lens is the first lens in Canon line up to use a Blue Spectrum Refractive Optics element (BR element) to reduce the chromatic aberration at the blue end of the spectrum. This results in a better optical quality. Further it has, according to Canon, an improved weather sealing. On other hand it is roughly 20 mm longer and 180 g heavier.

EF 35mm 2

The EF 35mm 2 is a prosumer level lens. It is constructed with a plastic body and a metal mount. This lens features a distance window with infrared index. The maximum aperture of 2 gives this lens the ability to create depth of field effects, but not to the same shallowness of the EF 35mm 1.4L USM, while its five-blade diaphragm may produce background blur ( bokeh). The optical construction of this lens contains seven lens elements, without any special lens elements. It uses a linear extension focusing system, powered by an AFD motor. Auto focus speed of this lens is moderately fast, but focusing does make some sound. The front of the lens does not rotate when focusing, but does extend.

EF 35mm 2 IS USM

The EF 35mm 2 is an enthusiast-level lens. Like the original version of the 2 lens, it has a plastic body and a metal mount, but adds

. It also has an eight-blade diaphragm with rounded blades, as opposed to the eight non-rounded blades of the 1.4L lens and the five non-rounded blades of the original 2 model. This lens features a distance window with infrared index. The optical construction of this lens contains 10 elements in 8 groups, including one molded aspherical element. It uses a ring-type USM motor. The front of the lens neither rotates nor extends when focusing.

EF-S 35mm 2.8 Macro IS STM

The EF-S 35 mm 2.8 Macro IS STM, like all other EF-S lenses, can only be mounted to a Canon camera with EF-S mount and not to a camera with EF mount. The lens has
