The Canon EF 55-200mm f/4.5-5.6 USM is a variable-aperture telephoto zoom for the Canon EF autofocus mount, designed as a compact consumer telephoto for 35mm film SLRs and later compatible with EOS digital bodies. The USM designation indicates an Ultrasonic Motor for autofocus, and the lens was aimed at amateur photographers wanting an affordable reach beyond the standard kit zoom.

At UK auction in recent years, hammer prices for this lens have been modest, with recorded results of £20 and £45 — placing the saleroom value firmly at the budget end of the EF telephoto market in 2026. With only two sales on record, the median sits around £32, and clean working copies tend to sell for the upper end of that range while scruffy examples fetch less. Buyers should remember these are wholesale auction levels, so retail asking prices from dealers will typically be higher.
