I finally read enough and got the stop action I needed in this gym. I have a 40d and I used my 17-55 for this shot. Unfortunately that resulted in ISO 3200,f2.8,1/620 at 42mm. I've used Aperture to reduce noise and this is the best I can do with my limited PP skills. I've been thinking about getting either a 50d or 7d (better/faster focusing) to replace my 40d or getting new glass (EF 85 1.8 or 70-200 f2.8-I). I will be needing longer reach anyway for spring baseball and football. What should I purchase or do differently in this situation? Thanks.
