Canon EF 100-300mm f/4.5-5.6 USM Zoom Lens

Telephoto zoom lenses allow you to capture details normally missed by the eye. Capture the far off action of fast-paced sports or zoom in for an intimate portrait with a blurred background. In addition, the unique feature of these lenses to compress images allows you to create a variety of impressive images. Canon EF 100-300mm f/4.5-5.6 USM is a highly practical and portable telephoto zoom lens. The five zoom groups make the length only 4.8 in. (121.5mm). With rear focusing, the lens does not change length or rotate during focusing. Any filter effects therefore remain intact. It also makes auto focusing quick and quiet.
