Description
Canon EF Autofocus Lenses Canon's reputation for excellence in optics has been well established for years. And with the introduction of EF lenses for the EOS, it's only getting better. EF Lenses have the largest diameter mount of any 35mm camera, which not only strengthens the whole system, but permits optical innovations never before possible. L-Series lenses have better sharpness and contrast because Canon uses aspherical elements to eliminate spherical aberrations. In addition, the L-Series telephotos use UD (Ultra-low Dispersion) glass to reduce chromatic aberration resulting in more accurate colors. A built-in Ultrasonic focusing Motor (indicated by USM) provides pro-quality AF speed with split-second accuracy. A modern design that's optimized for select Canon EOS digital SLRs. Its angle of view is equivalent to a 96mm lens on a 35mm camera, with a floating optical system that can focus down to full life-size (1:1) magnification. Inner focusing, driven by a silent and powerful ring-type USM, means the lens' overall length never changes during focus. This lens is a wonderful multi-purpose lens that's equally at home shooting macro shots, portraits or available-light photos. Like all Canon EF-S Lenses, its use is restricted to the EOS 20D, EOS Digital Rebel and EOS Digital Rebel XT cameras (as of February 2005).
