The stellar combination of superlative optics, astonishing performance and brilliant construction, the EF 400mm f/2.8L IS II USM super telephoto is the professional's choice for a long lens, and perfect for nature and wildlife photography. Over 28% lighter than its predecessor and now the lightest lens in its class, the EF 400mm f/2.8L IS II USM features Fluorite optics that deliver sharper images with less chromatic aberration, a completely redesigned Image Stabilization system that offers up to four extra stops of performance, a newly-developed Fluorine coating that keeps soiling, smears and fingerprints to a minimum, plus new construction in line with only the best that Canon has to offer. 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/2.8L IS II USM allows for easy panning and is ideally positioned for professional action photography. With a new security slot for wire-type security locks, buttons and switches are redesigned for intuitive, deliberate operation, and dust and water sealing keeps the lens functioning flawlessly in even the most challenging environments.
