Ideal for travel, mid-range nature/wildlife and general
photography, the 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.
Note: Only compatible with the 20D
and Digital Rebel (a.k.a 300D) digital cameras.
Note: Only Canon Extension Tube EF
25 II and 12 II fit on this lens.
