I think four photos for one post might be a record. My rules, and I'll break em' if I want to. The girls had fun watching ducks, climbing trees, playing frisbee, exploring the Park and leaping through the air among other stuff.
I do have some of those shots, but I was focusing (in the general sense) on the girls here and the ones with the frisbee in focus were just not that interesting. Don't hate me, but focusing on moving subjects is actually pretty easy with my camera. :) The autofocus capability of the 5D mkiii is superb, and that is most noticeable in servo mode when focusing on fast-moving subjects.
The second picture, the frisbee shot. Did u ever try to get the focal point on the frisbee??.. with whatever camera I have access to, I never managed a decent shot like that. I was trying it on a flying ball, which is much difficult, but I think it lot depend on the equipment you have. Frisbee, might be a little more easier, cos it moves a slower.
