Summary: Performance of the lens is disappointing - for ~US$1,500 we expect a lens that performs consistently well and that's where Canon EF 70-200mm f/2.8L IS USM fails. The lens shows very good performance in the shorter zoom range (70-135mm), but falls short towards the longer end.
Conclusion: The Canon 70-200mm F2.8 L IS USM is quite simply an excellent lens, which will reward users with quality images in almost every situation. On full-frame 35mm, sharpness is very good even wide open, becoming excellent corner-to-corner when stopped down.
Pros: Superb build quality, Highly effective image stabilization, Excellent autofocus and manual override, Consistently high image quality across almost all of the range
Cons: Slightly soft wide open (most notably on APS-C), Average close-up performance, Somewhat susceptible to flare with direct light sources in or close to the frame
Excerpt: You cannot be a professional photographer without a high-quality, high-speed telephoto zoom lens. Within the Canon EOS system, three such lenses are available: All of these provide very high image quality. All have ultrasonic motors and allow for full-time manual focus.
Conclusion: For most photographic applications, either 70-200mm f/2.8 lens is an outstanding tool that produces exceptional image quality. Deciding whether to buy the IS lens or the non-IS lens should probably revolve around the photographer's perceived need to have image stabilization.

26 February 2009
Conclusion: It was about time. The old Canon EF 70-200mm f/2.8 USM L IS (mk I) was a good lens but hardly something to rave about especially when used at 200mm. Canon claims to have the leadership in the tele lens arena and they probably do but so far with the exception of this lens segment.
Excerpt: The Canon 70-200mm f/2.8 IS offers a lot to professional photographers in terms of rugged design and functionality. It comes in the Canon L series classic white finish and will make any user look more businesslike. We could find no fault with the design and handling.

15 April 2008
Conclusion: The Canon EF 70-200mm f/2.8 USM IS is a very good lens but not a stellar one. The resolution characteristic is excellent at 70mm and 135mm but at 200mm it disappoints - more so regarding its price tag.
