The Canon EF 400mm F5.6L USM is a telephoto prime lens for Canon's full-frame and APS-C DSLRs, designed with portability and handling ease in mind. Trading brightness for size (and cost) the 400mm F5.6L's optical construction is relatively simple, comprising seven elements in six groups, but contains one Super UD element, whose characteristics are similar to fluorite, and one UD element. Optically, this lens is outstanding, but its slow maximum aperture and lack of image stabilization could limiting factors in some situations. The lens is equipped with a built-in hood and a detachable tripod mount.
