TSEvanson,


It sounds like we have nearly identical setups, 18-55 kit, 50 f/1.8, and 70-200 f/4. I got the 70-200 to go on my 30D as a poor man's sports shooting setup. I mainly shoot my daughter and her soccer team.


Oren,


I found Brian's reviews to be spot on. I some times wish I had the 2.8 version on heavily overcast days, or games that are near sunrise/sunset. At these times I have to push the ISO up to get the shutter speed needed. However, I did shot a bunch of wrestling from the cheap seats at the NCAA Div.1 national championships. If I remember I was at ISO 800, and about 1/250th on the shutter. Handholding, if you are careful about it, is still possible. I got a lot of clear and reasonably sharp shots this way. In my situation, the extra cost was the problem more than the shooting.
