Canon EF 85mm f/1.8 USM Specifications
A highly practical medium telephoto lens with superb delineation and portability, the Canon EF 85mm lens produces sharp and clear images at all apertures. Through computer simulations, the lens has been designed to give beautiful background blur, thereby bringing your subject into crisp view. The ring-type ultra-sonic monitor (USM) and fast f/1.8 aperture, meanwhile, helps the subject zip into focus in the viewfinder. And because the front lens group does not rotate during focusing, special filter effects are not affected. Best of all, the standard zoom lens–with its natural angle of view and perspective–captures the subject plainly, making it excellent for portraits and images that require a natural depth of field. As with all Canon lenses, the lens carries a one-year warranty.
