Canon EFS 17-85mm F 4-5.6 IS USM lens.
The EFS 17-85mm 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 27-136mm , 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.

Ring type USM focusing with full time manual override.
