Canon EF 400mm lens
The Canon EF 400mm are seven
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,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.
