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. Highly portable lens with high optical performance and light weight of 12 oz. (340 g). A very practical ultra-wide-angle zoom. The large front lens group minimizes peripheral darkening, and the flare-blocking diaphragm minimizes flare. [+]
