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,
with better handling, lighter weight and the
world's fastest AF speed among 400mm f/2.8
lenses. Durability and weather resistance are
world class. A complete redesign of optics has
resulted in Canon's best image quality ever in a
400mm lens.
