The Canon 70-200mm ƒ/2.8L USM performed very well in our tests, perhaps not as sharp as we'd like at 200mm and ƒ/2.8, but quite impressive at 70mm. CA tolerance is very good, distortion is low, and corner shading is very low. Build quality is very high, and autofocus performance is excellent. For the money, you can't go wrong with this lens.

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.
