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

This is a real gun
It's really difficult to add something new as everybody agrees that this is an amazing lens. Before I bought this lens I had owned Canon 70-200 f/4 non-IS version. It was also excellent lens in terms of image quality but this one adds faster aperture and more importantly excellent Image Stabilization.
Lens is really heavy comparing to non-IS version of 70-200 f/4 but that extra weight is worth of it. Pictures are excellently sharp, you can shoot hand-held with times below 1/100 sec. which is a dramatic improvement.
I believe any of Canon 70-200 lenses is great but not each is usable in low light conditions without tripod. 70-200 f/2.8L IS excels in such situations so if you're sure you'll be dealing with low light, this lens is for you.
It's excellent for wedding photography, portraits, nature, animals etc.

Amazingly quick autofocus, but a little heavy
I bought this lens for shooting softball action in early evening, twilight, and night games. The autofocus is unbelievably quick and impressive. It's important to remember to set it to IS mode 2 during action. I forgot a few times and the images were not clear enough. The zoom ring is smooth and is conveniently placed. I chose this over the 80-300 mm because the 70-200 got better ratings regarding picture quality and it has the f/2.8. The range of 70-125 is great for infield and shallow outfield, but beyond that it needs to be on a tripod or monopod. I'm thinking of renting 100-400 to see if that works better for my needs. I've taken a few shots indoors of my dog and wasn't impressed -I'm sure it is due to my lack of skills and not the lens itself. I haven't learned to use a monopod so I've been hand holding it while attached to the Canon 40D. I don't think it's too heavy, but I've been getting flair-ups in my carpel tunnel pain the day after using this lens.

great lens!
This is a wonderful lens. Well worth the money. The senior portraits I took came out beautifully. Works great for outdoor shots!
