The Canon EF 70-300mm f4.0-5.6DO IS USM is a superior performance, ultra-compact telephoto zoom lens with Canon's Image Stabilization. These Diffractive Optics elements are combined to reduce size and boost image quality. AF is super-fast and silent with a ring-type USM, and it focuses down to 4.6 feet – without rotating the front element. A new zoom lock button keeps the lens safe and secure when not in use or used at the wide angle.
