Ideal for travel, mid-range nature/wildlife and general photography, the Canon EF-S 17-85mm f/4-5.6 IS USM is a lightweight, compact all-purpose "standard" zoom lens. Equivalent to a 28-135mm lens in 35mm format, this EF-S lens brings 5x wide-angle to tele coverage to EOS 20D and Digital Rebel shooters.
This lens features Canon's latest optical Image Stabilizer technology, providing up to 3-stop compensation for image blur caused by camera shake and slow shutter speeds. The lens has a 17 element, 12 group construction, including one double-sided aspherical element for crisp, high contrast corner-to-corner detail.
A ring-type USM means both fast and silent AF, as well as full-time manual focus when in the AF mode.
Designed specifically for digital photography, the lens has specially shaped lens elements and coatings to suppress ghosting and flare, which can be caused by reflections off digital camera sensors. An exclusive optional lens hood can further reduce the incidence of flare.
