Lens Review
Introduction | Canon EF 400mm f2.8L IS II USM sensor performance | Canon EF 400mm f2.8L IS II USM versus competition | Conclusion

If you need a wide 400mm lens for your Canon camera and you can afford it – and you can justify it – this lens is one of the sharpest DxOMark has tested on a Canon camera. It is big, it is very heavy, (though lighter than the Nikkor!) and it will require real skill to exploit the amazing effect that an aperture of f/2.8 can give on such a long lens, but it is very unlikely that you will be disappointed.
