Like all EF lenses, the EF 55-200 f/4.5-5.6 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.Superb technology and ergonomics
The EF 55-200 f/4.5-5.6 II USM is compact and lightweight, with 13 lens elements in 13 groups resulting in consistent image sharpness. It incorporates Ultra Sonic Motor (USM) technology and improved electronic circuitry to provide high-speed Auto-focus. Externally, the lens has an ergonomic rubber pattern zoom ring that’s easy to grip, while its black body and distinctive markings match the design of the latest EOS cameras.High-speed Auto-focus
The EF 55-200 f/4.5-5.6 II USM’s fast Auto-focus is the
result of an improved AF drive pattern, a new type of Central Processing Unit (CPU) for faster communication, and a new AF algorithm.Optimised lens coatings
The EF 55-200 f/4.5-5.6 II USM’s lens coatings have been optimised to minimise ghosting and flare – something that’s more prone to occur with digital cameras than film cameras. The coatings reduce reflections off the rear of the lens to deliver crisp, undistorted digital images.Lead-free glass optical system
