7D AF does not disappoint.....
Jun 27, 2011

The "Tour of America's Dairyland" bike races were in Milwaukee this past weekend and I spent about 2 hours getting some shots late Saturday afternoon. I did this race once before in 2009 with my 50D and it's a great opportunity for photography and again I was blessed with heavily filtered Sun.

I was very pleased with the AF performance on my 7D with the 70~200f4LIS (the only lens I used) and afterward am disappointed I did not try a few more AF modes. I did the entire race in AI Servo with single point expansion moving the point around in the frame for different shooting positions. In retrospect, I should have thought to try all points active and test the ability of the AF to lock and follow the subject as this would have been beneficial in certain circumstances.

I shot just over 300 total frames and have 243 that are tack sharp at the positioned AF point. Most of the others were mistakes by me and/or poor exposure due to trying manual for a period. I also canned many of my slow shutter panning tries so overall the AF performed extremely well.

Several (many) of these are crops to remove distracting elements and tighten the framing. That's when you really appreciate 18 MP's.

If you're interested I've posted about 50 shots so far to my PBASE page.

C&C welcome as I'm not a sports shooter.
