The Canon EF-S 15-85mm f/3.5-5.6 IS USM standard zoom lens sets a new standard for everyday photography on APS-C sensors. With a focal length range equivalent to 24-136mm in 35mm format, image stabilization and high-precision optics, this lens offers stellar performance from wide-angle through to telephoto. The Image Stabilization system allows you to shoot sharp images with a 4-stop advantage under less-than-optimum lighting conditions. Plus the Ultra Sonic Motor (USM) technology provides fast and quiet focus control with on-demand manual override when shooting in AF mode.
