    Overview

    The Canon EF-S 15-85mm f/3.5-5.6 IS USM is a versatile standard zoom for APS-C cameras, offering a 24-136mm equivalent range. It delivers excellent center sharpness even wide open, with slightly weaker corners at 50-70mm. Build quality is improved over previous EF-S zooms, using plastic but feeling solid. The ring-type USM provides fast, silent AF with full-time manual override. Image stabilization is rated for four stops. It suits enthusiasts wanting a wide-to-telephoto walkaround lens without sacrificing optical quality, though it is slower (f/3.5-5.6) and priced higher than kit lenses.
