The standard lens for many professional sports and nature photographers. The latest image-stabilized version of the 400mm f/2.8L is the best yet -- lighter, with better handling and controls, the world's fastest AF speed among 400mm f/2.8 lenses (with the EOS-3, as of 5/99), and unmatched durability and weather resistance. Completely redesigned optically, for Canon's best image quality ever in a 400mm lens.
