Canon EF 400mm lens

The Canon EF 400mm are seven super-telephoto lenses made by Canon. These lenses have an EF mount that work with the EOS line of cameras. These lenses are widely used by sports and wildlife photographers.^[1]

Canon currently manufactures three 400mm prime lenses:

EF 400mm f/2.8L IS II USM^[2]
EF 400mm f/4 DO IS II USM
EF 400mm f/5.6L USM

The EF 400mm f/5.6L USM is Canon's least expensive 400mm lens and one of the best deals for a super telephoto 400mm focal length lens in the industry. Exceptional sharpness, minimal vignetting, very low distortion, and superb handling of chromatic aberration means this lens does not require image corrections in digital post production software. Having a maximum aperture of f/5.6, it is relatively slow.

The 400mm f/4 DO IS II USM, which replaced an earlier version of the same lens in 2014,^[3] is one of only two Canon lenses that make use of diffractive optics (the other is the Canon EF 70-300mm lens). The use of diffractive optics allows the lens to be significantly lighter than it might otherwise be, but at the cost of some image quality.^[4]^[5]

These lenses are compatible with the Canon Extender EF teleconverters.
