[QUOTE="WayneF, post: 528130, member: 12496"] There are two definitions of multiple focus points, and it's not always clear who's discussing what. Nikon offers Single Point focus, where we see one focus point and we can move it to one of several multiple locations in the frame, center, or far left, wherever, but it remains one single point at wherever we put it. [B]It is for stationary objects[/B]. We put the focus where we want it. Some of the cameras give us choices of how many points or places where we can move that single point, like 11 or 51 places (finer or coarser positioning), but it's still Single Point focusing, at the one place of our own choice. Or there is a Dynamic Area AF choice, offering several to many focus points available, and the system automation chooses some one or a few of them, on something where it chooses it wants to focus. [B]This is for moving subjects[/B], to help follow them. I'd say fast moving, mild movement is no problem with Single Point. It is not in our control, except it does sort of favor the general central area of the frame. IMO, for when you don't much care where... I don't do much motion chasing, and I really can't imagine not using Single Point focus. I want it to be where I put it.. like on the near eye, or wherever, but my choice. I do move it around in some cases. More often I will lock it with half press in the center, and then shift the camera to frame it different. [/QUOTE]
