I have had the 7d for about 10 days and have shot about 6000 shots mostly hockey and volleyball. Have been mostly impressed with this camera . I have been shooting with a 30d and 50d prior to the 7d. It definitely has a higher learning curve with all the af focus options. If your interested check out some samples at this site. http://rayssportsphotos.smugmug.com/Sports/7d-sports-shots/9867076_2bni6#673066870_LX5bR
I will update settings that I find work well as I get more familiar with the camera and all its options.
This camera is awesome for indoor sports. I have been using mine for basketball and wrestling shooting from 3200 to 5000 ISO and getting shots I could never have with my 40 or 50D
Great shots, you would appear to have the 7D dialed in very well. I would be most interested for you to comment on your current settings with these set of shots and what PP you are doing. Thanks much, love those hockey shots.
