The Canon EF 35mm lenses are a family of wide angle prime lenses with EF mount made by Canon Inc. The family also includes one EF-S lens that only mounts on Canon bodies with APS-C sensors.
Focal lengths at 35mm or less are considered wide angle on 135 film 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 f/1.4L II USM, the f/2 IS USM and the EF-S f/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.
