Did a shoot this week of some Track and Field and thought I would share with you some of the best action that I captured.

your first shot is out of focus. What AF mode are you using, and what set-up? The second high jump shot is good, just crop tighter. You get a lot more intensity and emotion with a tighter crop. The last shot is ruined by a busy background. The people are just too distracting. Was this the triple jump or long jump?

WHat aperture were you shooting at? ALways open up as much as possible w/ sports, since you're looking to isolate the subject.
