[QUOTE="nickt, post: 664270, member: 4923"] I agree with what the others said. Just to add, there are two components to focus... How the focus point is acquired (S, auto, d9, dynamic, etc) and how the focus motor behaves after acquiring the focus point (af-s vs af-c). Then we have menu A1 and A2 that determines whether the shutter must wait for focus. The default is af-s will wait (focus priority), af-c will not wait (release priority.) You mention you have AF ON and af-c, I take that to mean you are using back button focus. In that case, it is on you to be sure you have focus. When shooting action, you will get some out of focus images using bbf, especially if you are not sure what af area mode you are in. I would use single point if there is a particular player you need to follow. If the pictures are still in camera, you can turn on the option and get to the screen to see what focus point was used. If after the fact, Nikon's NX-i or NX-d software will show you the focus point that the camera used. I tend to stick with single point in most situations. [/QUOTE]
