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.
