Macro photography with AI servo - DSLR Tips

The Canon 7D has a feature which changes the way the 7D focuses with a Canon macro lens with a USM motor. It works great!....go to this site and search for Canon 7D and find the series called "A balance of features and performance" and it's in part 2 of 3 at 12 minutes into the video. It's Rudy Winston from Canon USA so he knows what he is saying. Very cool feature. www.video.bhphotovideo.com
