Here's a new 7D AF test. These were shot in AI Focus (not AI Servo) using single focus point with expansion (center focus point manually selected), and single shot shooting mode. Please note that these images are not all a continuous focus sequence. As the dog was running around I shot several shots in a row, waited for him to move around, then acquired focus again and took some more shots. Please also note that these are crops from the original images and were downsized quite a bit before posting, so the image quality is not nearly equal to that of the original images.
