EF 70-200mm f/2.8L IS USM
7469

Overview
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. Constructed to pro standards, this fast zoom is also highly resistant to dust and moisture, too.

awesome lens
This lens is well worth the price. It is sharp, clear and precise through out its range from 70-200mm. In gyms with very poor lighting, this lens shines! I take basketball pictures and they are awesome with this lens. It makes me looks like a professional photographer with years of experience. Another aspect of the lens that I never thought of is its white color. When people see that lens on your camera, people give you more respect and access to more areas of a football field, gym or track. They believe you are a true professional when you carry and use this lens.

Race results as promised
After a 30 year hiatus from motorcycle race photography I took my first race and the results were spectacular. Used the lens at 200mm with 1.4X ll convertor. Even in the overcast the autofocus was fast and the shots were very sharp. Panning required me to be in AI servo, mode 2 AF and in most cases it worked very well, Would have liked to try the second day when the light was better.That day was dedicated to working with my 400mm 5.6 (see review). I will switch back to center point autofocus as it offers more control over a particular subject in a pack. Overall, my experience with this lens makes it highly recommended. I just have to work on my panning, especially on the straights where bikes are moving 250+ft./second.

Great Lens though flawed
I have owned this lens for 9 years took my wedding with it on a 10D. Great portraiture lens especially in low light. In any situation the bokeh is the best. Nature shots, its a bit bulky and heavy for carry. I use it with a Canon 1.4x ll converter and still wanting for more magnification. The 2x at 200 is soft. The auto focus could be faster and the minimum focus distance could be a little shorter. Overall, I love this lens. My only real beef is that I must have received a product where the bayonett is on the sloppy side of the tolerence as it moves in place. None of my current or former Canon lenses do this. For Birds I have been taking out my 400mm 5.6 with a 1.4x at 560mm it is still tack sharp. I will be changing to motorcycle racing events and will report on the 70-200 and its IS functions soon.
