Canon EF 20-35mm f/3.5-4.5 USM
Highly portable lens with high optical performance and light weight of 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.
