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 has manufactured four 400mm prime lenses:

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

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 EF 70–300mm f/4.5–5.6 DO IS USM). The use of diffractive optics allows the lens to be significantly lighter than it might otherwise be.^[4]^[5]

These lenses are compatible with the Canon Extender EF teleconverters.
