This large-apertured, high-performance lens from Canon is well suited to sports, wildlife, portraits and wedding photography. The Canon EF 200mm F2 L IS USM lens features fast USM driven autofocus designed to capture the action quickly and accurately, while the built in IS makes hand-held shooting a possibility. The F2 aperture produces stunning shallow depths of field and thanks to the eight blade aperture, the out of focus areas are beautiful and smooth.
