EF-S 17-85mm f/4-5.6 IS USM
• This new EF-S lens brings true wide-angle to tele coverage to EOS 20D and Digital Rebel shooters.
• It has Canon's Image Stabilization system, allowing safe hand-holding at speeds up to three stops slower than otherwise possible.
• And of course, it's optically optimized for digital SLRs.
• A ring- type USM means both fast and silent AF, as well as full-time manual focus when in the AF mode.
