Equivalent to a 28-135mm lens, 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.
