Equivalent to a 16-35mm zoom for a 35mm film camera, it offers excellent performance and optics designed from the ground-up for digital SLR use. Excluding fisheye lenses, the EF-S 10-22mm f/3.5-4.5 USM lens has the shortest minimum focal length ever offered for interchangeable lens digital SLRs with APS-C image sensors.

Photographers will achieve consistently excellent image quality throughout the zoom range of this lens because of its 3 aspherical elements and 1 Super-UD element in a 13-element optical formula. A ring-type ultrasonic focusing motor (USM) provides fast and silent AF along with full-time manual focus.
