Amazon.com Product Description
Incorporating Canon's second-generation Image Stabilization technology, this 70-200mm telephoto zoom responds in as little as 0.5 seconds while providing up to three stops of correction for camera shake. As a result, you can easily capture the far-off action of fast-paced sports or zoom in for an intimate portrait with a blurred background. The lens's autofocus (AF) system, meanwhile, has been refined for better response time and tracking speed. And photographers will love the new eight-blade circular aperture, which offers a more pleasing out-of-focus image. Constructed to pro standards, the EF 70-200mm lens is highly dust- and moisture-resistant and carries a one-year warranty.

Customer Reviews

A great sports telephoto
Very sharp, great bokeh, very fast and silent AF. Practically no chromatic aberration and vignetting (except perhaps at F2.8). Ideal for sports shooting. With the IS one can shoot usable pictures at 1/20 sec. Highly recommended. See also:

Great Telephoto Lens
Excellent lens that produces great quality images. It is a bit on the heavy side, but well worth the extra weight. I have used it for over a year and the improved quality of my images is really amazing. If you serious about producing excellent images this is the lens for you.

fine lens
got this lens because of the reviews. there is no question the glass is outstanding. the night time pictures are out of this world. shot a thunderstorm, unbelievable pictures.
overall very very nice. But the weight is an issue. it is pretty darn heavy after two hours. i would not use it as an everyday lens. it is worth having in the bag, but until i get a lot stronger, it is my #2 lens. (24-135mm #1)
