I shot this with a 5DmkII and a 70-200mm f/4 L, AF AI Servo mode. As you can tell, the image is focused just behind the runner, yet I had the focal point zeroed in on the runner's chest the entire time. Otherwise, the lens autofocuses really well. Is it me, or my gear? Should I plan on focusing just in front of the runner to compensate for AF lag?
Granted, my body/lens combo is suited more for landscapes than it is high school football. The easy answer here is to say "get a 70-200mm f/2.8 L IS", but that ain't gonna happen any time soon.
Thanks in advance for your thoughts. EXIF data is listed just below the image. See the largest file size
for more detail if you need to. Touchdown!
