Canon EOS-1D Mark IV AF Testing

[Photo-John]

These two are both from the same line for Jenni. I wanted to test her coming right at me for a series of shots. Usually, that's where AI Servo has the most difficulty, since the focus changes so much from shot to shot. And like the first aspen shot I posted, the AF kept right up with this series until she was really close. I just set the camera to 10 FPS, kept the middle focus point on my subject and then picked the best images later, on the computer.
