A compact, redesigned telephoto zoom lens for both digital and analog EOS SLR photography. Like all EF lenses, the EF 55-200 f4.5-5.6 II USM works with all Canon EOS cameras. When mounted on a digital SLR with APS-C size sensor, its effective focal length provides the equivalent of 88-320mm in 35mm format. It\'s an excellent additional lens to the EF-S 18-55mm f/3.5-5.6 – the standard lens for the EOS 300D.
