Canon Zoom Super Wide Angle EF 20-35mm f/3.5-4.5 USM Autofocus Lens

Highly portable lens with high optical performance and light weight of just 0.74 lb. A very practical ultra-wideangle zoom. The large front lens group minimizes peripheral darkening, and the diaphragm minimizes flare. Distortion is well corrected, and the internal focusing allows easy use of circular filters such as a polarizer.
