Canon EF 300mm f/2.8L IS USM Telephoto Lens for Canon SLR Cameras

Telephoto lens newly equipped with an Image Stabilizer enabling hand-held shooting for easier movement. The fluorite element and two UD-glass elements effectively correct the chromatic aberrations prone to occur with telephoto lenses. With the EOS-1v and EOS-3 the AF speed becomes the world’s fastest. To reduce the overall weight and enhance portability the lens barrel and many other exterior parts use a magnesium-alloy. Also the detachable tripod collar revolves smoothly and locks securely.
