The Canon EF-S 17-55mm f/2.8 IS USM Lens is a
large-aperture lens specifically designed for EF-S type digital SLR
cameras, and that offers a super wide angle to short telephoto zoom range,
with built-in Image Stabilization. The focal length is equivalent to
approx. 27-88mm in 35mm format.
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. This ensures clear,
crisp images, even in dim light.
Designed specifically for digital
photography, the lens has specially shaped lens elements and Super Spectra
coatings to suppress ghosting and flare, which can be caused by
reflections off digital camera sensors.
Note: Only Canon Extension Tube EF 25 II
and 12 II fit on this lens.
Note: Not suitable for 35mm film SLR
cameras or digital camera with image sensor bigger than APS-C size, only
fits on the EOS Digital Rebel series or 30D and 20D SLR cameras.
