[QUOTE="hark, post: 660425, member: 13196"] Yes, I was asking about the settings people use with BBF. But more specifically, what type of focus point(s) do they use. In the video posted earlier, Steve Perry talks about the different types of Auto Focus: single point AF, dynamic AF (usually at least 2 types of dynamic settings that involve more than 1 point), group AF, and 3D AF. If you aren't sure about the differences between them, watch the video to see examples of each one. Before trying all of them, I really expected I'd want 3D...that is until I actually used it. The focus point was flying all over my viewfinder. That particular setting works better when your subject has a background that is entirely different in contrast (such as a bird against a completely blue sky). Steve says 3D AF is better for sports, and after trying it out with wildlife, I can see why. The camera tried to use the trees in the background to be part of my subject--that caused the focus point to jump back and forth between all the trees and my subject. [/QUOTE]
