Canon EF-S 17-85mm f/4-5.6 IS USM
Equivalent to a 28-135mm lens, this EF-S lens brings true wide-angle to tele coverage to Canon EOS digital SLRs. It has Canon's Image Stabilization system, allowing safe hand-holding at speeds up to three stops slower than otherwise possible. A ring-type USM means both fast and silent AF, as well as full-time manual focus when in the AF mode. Specification17 - 85mm; 1:4-5.6Lens Construction: 17 elements in 12 groupsDiagonal Angle of V
