I hope that you'll enjoy the lens. It can do quite well, if you can tolerate the weight. I got it solely to use for indoor sports (horse shows) and it's often still not fast enough, so I use a faster prime (e.g., 85mm f/1.8, 100mm f/2--eventually, I'll get a 135mm f/2). For outdoors, I usually use the 70-200mm f/4L IS I had for quite a while before getting the f/2.8L IS. It's a lot lighter, faster focusing, sharper and has better IS. (Ken Rockwell, among others, found that he could shoot handheld at lower shutter speeds with the f/4L IS than with the f/2.8L IS. I can often get decent shots handheld at 1/15 while at 200mm. The best I can do with the f/2.8L IS is about 1/25-1/30.)


Of course, if I'd bought the f/2.8L IS lens first, I wouldn't have bought the f/4L IS.
