The Canon EF 400mm f/2.8L IS II USM Telephoto Lens is the perfect choice for nature, wildlife and sports photographers. The lens is extremely light for its class and the Image Stabilization system offers up to four extra stops of performance.
With a third Image Stabilization mode (Mode 3) that activates IS only when the shutter button is fully pressed, and giving the equivalent effect of a shutter speed four stops faster, the EF 400mm f/2.8 IS II USM allows for easy panning and is ideally positioned for professional action photography. Fast, quiet Auto Focusing (AF) is provided by a ring-type fast Ultra-Sonic Motor (USM), dedicated AF algorithms and a high-speed CPU, which offers quick and accurate focusing during shooting.
