EF-S 17-85mm f/4-5.6 IS USM

The Canon EF-S 17-85mm f/4-5.6 IS USM is a standard zoom lens designed for Canon APS-C-format DSLRs, offering a 27.2-136mm equivalent focal length range suitable for general-purpose photography. The optical design incorporates one dual-sided aspherical element and Super Spectra coating to minimize distortion, aberrations, and flare while delivering improved sharpness and color accuracy. An Optical Image Stabilizer reduces camera shake by up to three stops, enabling handheld shooting in challenging lighting conditions.

The lens features a ring-type Ultrasonic Motor for fast and quiet autofocus with full-time manual focus override, along with a rounded six-blade diaphragm that contributes to pleasing out-of-focus rendering. The compact lens weighs approximately 1.05 pounds and accepts 67mm filters, making it a practical option for everyday photography with EF-S-mount Canon DSLR cameras.
