Lighter by more than 1.2 pounds (545g) than the 70-200 f/2.8L zoom lens, this fast telephoto lens is a perfect alternative for low-light shooting or just reducing weight in the gadget bag. Two UD-glass elements and internal rear-group focusing are among its optical highlights, and it’s fully compatible with Canon’s EF 1.4x II and 2x II tele extenders. A detachable hood is included, and Tripod Ring A (B) is available as an accessory.
