The Canon EF-S 17-55mm f/2.8 IS USM is a fast zooming lens designed specifically for the Canon EOS 30D, 20D, 20Da, Digital Rebel XT and Digital Rebel. This lens has a large f/2.8 aperture, giving it increased light gathering abilities for distant targets. The aperture is circular and produces a shallow depth-of-field, naturally blurring the background and keeping the subject the focus of attention. The lens groups shift as the camera moves, creating a steady image even in low light conditions. Inner focusing allows the autofocus to be set without the need to adjust focus on the camera, and full-time manual allows for quick adjustments on the fly. Standard 77mm filters can use a screw-on attachment.
