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. International Version with 1-year seller warranty. Warranty is managed directly by the seller instead of the manufacturer. To use the warranty, please email customer service.
