Canon Zoom lens EF-S 15-85mm f/3.5–5.6 IS USM lens.

The EFS 15-85mm lens is Canon’s logical upgrade from the basic 18-55 kit lens supplied with its APS-C DSLRs. With a 35mm equivalent focal length of 24-136mm , it covers a decent wide-angle to telephoto range , making it useful as walk around lens which will cover a wide range of photographic opportunities. It also sports Canon second generation optical image stabilizer, which allows hand-holding at slower shutter speeds than usual before the image  degrading effects of camera shake become apparent.

27-136mm Equivalent focal length range , F4-5.6 maximum aperture.

Optical stabilization – 3 stops.

Ring type USM focusing with full time manual override.

EF-S mount for Canon APS-C DSLRS only.
