"This exciting new 10-22 mm zoom lens provides ultra wide-angle coverage to the EOS 20D and Digital Rebel shooter. Equivalent to a 16-35mm zoom it offers excellent performance and optics designed from the ground-up for digital SLR use. Three Aspherical lens elements plus a Super-UD element assure image quality. Its ring-type USM means fast and silent AF along with full-time manual focus. It focuses as close as 9.5 inches."@en
