Canon EF-S 17-85mm 1:4-5.6 IS USM review: Digital Photography Review Canon EF-S 17-85mm 1:4-5.6 IS USM review. January 2008 EF-S mount for Canon APS-C dSLRS only; 78.5 mm diameter x 92 mm length (3.1 x 3.6 in)

Canon’s 9517A002 EF-S 17-85mm f/4-5.6 IS USM Standard Zoom Lens is equivalent to a 28-135mm lens and brings true wide-angle to tele coverage to EOS 60D, EOS 7D and Digital Rebel cameras. It has Canon’s Image Stabilization system, allowing safe hand-holding at speeds up to three stops slower than otherwise possible. 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.
