CANON 20-35mm f3.5-4.5 USM

A highly portable lens with high optical performance and a light weight of 12 oz. (340g). A very practical ultra-wide-angle zoom. The large front lens group minimizes peripheral darkening, and the flare-blocking diaphragm minimizes flare. Also, with lens group 2 being the zoom group, distortion is corrected.
