The short 70-200 tele-zoom is one of the most popular professional lenses. It covers a useful focal length range, good from portrait work to sports shooting and also for distant landscapes as well as details. Canon makes four of such lenses.

Canon makes two wide-angle zooms for full-frame cameras. Both are L-lenses, reasonably well-built, with fast USM autofocusing, a non-rotating front element, and an environmental rubber seal.

I consider this lens to be the best zoom ever […]
