Overview
The EF-S 17-55mm f/2.8 IS USM offers image quality on a par with Canon's highly regarded L-series lenses. It has a large maximum aperture which, combined with higher shutter speeds can minimize subject motion blur. Shallow depth-of-field separation of a subject from its background is much easier to achieve and the f/2.8 maximum aperture allows a bright finder and extremely precise focusing with f/2.8 compatible AF sensors.
The internal stabilization has a sharpness benefit equivalent to a three-stop faster shutter speed, making this lens outstanding in low light situations. Smaller and lighter than lenses of similar specifications, the EF-S 17-55 mm f/2.8 IS USM lens has a 35mm equivalent focal length of 27-88mm.
NOTE: This is an "EF-S" Series Lens and is compatible only with Digital SLR's that accept EF-S lenses like the EOS Digital Rebel , Digital Rebel XT, Digital Rebel XTi, Digital Rebel XSi, EOS 20D, EOS 30D, EOS40D and similar.
Do NOT Use With the EOS-5D, EOS-1D, EOS-1DS, EOS 1DS-Mark III Or Any Other EOS Camera.
