The Canon EF 28-135mm f/3.5-5.6 IS USM is a standard-range zoom lens for Canon's EF autofocus mount, covering moderate wide-angle through short telephoto. It combines Image Stabilization (IS) with a USM (Ultrasonic Motor) autofocus drive and was designed as a general-purpose walk-around zoom for 35mm SLR and later digital SLR bodies.

At recent UK auction, the four recorded hammer results for this lens span £50 to £88, with a median around £70 — prices that reflect wholesale saleroom levels rather than retail asking figures. As of 2026 the lens continues to change hands at this entry-level zoom tier, with cleaner, fully functional copies fetching nearer the top of the range and tired examples sliding toward the lower end. Expect the typical EF 28-135mm IS USM to be worth and sell for double-digit rather than triple-digit money in the auction market.
