Incorporating Canon’s second generation Image Stabilization technology, this telephoto zoom responds in as little as 0.5 seconds, while providing up to three stops of correction for camera shake. Its AF system has been refined for better response time and tracking speed. And even the new 8-blade circular aperture offers a more pleasing out-of-focus image.

Canon EF 70-200mm f/2.8 L IS USM Lens Review by the-digital-picture.com

Prior to the Canon EF 70-200mm f/2.8 L IS II USM Lens (review) being introduced, the Canon EF 70-200mm f/2.8 L IS USM Lens was my favorite and most-used lens.

Combining a very popular and very useful focal length range with excellent image quality, professional build quality, superb autofocus performance, a fast aperture and one of my favorite features – Canon’s valuable 3-stop Image Stabilization – makes the 70-200 IS one of Canon’s most desired lenses. When I really need to make every shot count, the 70-200 IS is one of the first lenses I will include in my bag. It is one of the most-professionally-used lenses available and finds a home in the kit of many, many serious amateurs as well.

The decision between the non-IS and the IS version of this lens is a no-brainer. The extra $750 gets you a lens with far greater versatility. It will get you shots that you otherwise will miss. If that’s not worth the extra money, I don’t know what is.
