The Canon EF 85mm is a highly practical telephoto lens offering superb delineation and portability. It has an 85 mm f/1.8 lens aperture and 85 mm focal length to bring subjects in closer, while providing a longer flash range and faster shutter speeds to freeze the action. In addition, Canon used computer simulations to design the lens so it creates beautiful background blurs. The front lens group on the EF 85mm does not rotate during focusing so special filter effects are not affected, and it has a powerful ring-type ultra-sonic monitor (USM) and fast 85 mm f/1.8 lens aperture with inner focusing and full-time manual focus. Featuring 1/3-stop speed advantage, a natural angle of view, and perspective for portraits and natural images alike, this is the ideal medium-range telephoto lens for everyday use.
