sorry I even bought it
From the time I have upgraded to this lens, There have been many instances where pictures will come out either fantastic or heavily flawed by being blurry and not focused at all. It took me a while to upgrade because it was a large jump from the rebel t3i and its corresponding lens to a 7d and this lens. i use this lens for action photography involving horses and I am having a serious problem with the auto focus. While all this time it is focused to the jump, the second I take the photo it becomes blurry and a waste of a good timed photo. One out of every 10 photos or so are a good quality and I am thinking about getting a new lens with a longer zoom and IMAGE STABILIZER. Not having the stabilizer kills me sometimes. But I do not want to buy the expensive lens that has it because I cannot afford it. I am stuck in a bad spot but am overall very unhappy with the lens and do not look forward to using it at shows.

My first L lens!!!!!
So this is my first L lens and I'm extremely satisfied with it. The quality of my shots blew me away. Perfect focus. Extremely crisp. The only complaint I have is that it is HEAVY! My wrist hurts from supporting the lens. Another thing is that people stare at it. A lot

Doesn't feel at all heavy, I thought this might be a problem. I debated over the 70-200 4L IS model and this one, decided on the 2.8 L. My wife didn't understand why I wanted to spend so much money on a lens, after she has seen the pictures it takes ..... well she didn't talk about that anymore. :)

I had a 70-300 tele before purchasing this lens. In every single way it is better. No chromatic aberrations have been noticed. I normally use this telephoto lens for sports and auto racing. It's got very fast auto focus which is a must when shooting sports. The colors are much richer. So far I haven't had any complaints with it, other than the heaviness of the lens. Some days I will be out for 6-10 hours shooting sports with this lens and after a while my back starts to hurt from lugging around this lens. The price is another issue, but honestly you get what you pay for and this lens is completely worth the money.
