Canon EF 400mm lens

Summary

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.

Use in astronomy

edit

Canon 400 mm f/2.8 L IS II USM lenses are used in the Dragonfly Telephoto Array.[7] The array is designed to image astronomical objects with low surface brightness such as some satellite galaxies.[8][7] The array started with three lenses but this has since increased to 24 with plans for 50.[7][8]
