Canon EF-S 10-22mm f/3.5-4.5 USM SLR Lens for EOS Digital SLRs EF-S Lenses By reducing the distance from the rear of the lens to the focal plane and reducing the size of the image circle to match the size of the APS-C imaging sensor used in digital SLRs such as the EOS 20D camera and Digital Rebel camera, Canon's EF-S lenses reduce the size, weight and cost of wide-angle lenses for these cameras while at the same time producing high image quality with superb resolution and contrast at all focal lengths. EF-S 10-22 3.5/4.5 USM This exciting new zoom lens provides ultra wide-angle coverage to the EOS 20D camera and Digital Rebel camera shooter. 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. Minimum focusing distance is 9.5 inches for breathtaking close-ups.
