"Medium telephoto lens with a macro feature for 1x magnification. Fluctuations in spherical aberrations caused by focusing are suppressed  and high-quality images are obtained at all focusing distances. With eight aperture blades  good background blur is obtained even when the aperture is decreased by one or two stops. A focusing limiter which limits the magnification to 0.25x is built-in.  "@en

"This exciting zoom lens provides ultra wide-angle coverage to the EOS 20D, 30D, 40D, 50D and Digital Rebel SLRs. 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."
