Hi Nikonites!
Question 1:
I was looking at Area AF focal points using the feature in NX Studio and noticed that some of my NEF images showed them while some did not. I believe that this may be because I hit my back button focus before shot 1, which shows the focus points, and then did not press again before taking shots 2 and 3, which do NOT show focus points. Image 4 again shows them, which matches with probably me feeling that I had focus and didn't need to refocus in the moment. Is this a correct assumption? Do the focus points only show up if you hit bbf prior to each shot? If so....why? Aren't the focus points still there on shots 2 and 3? I don't see any change in the focus, it would simply be nice to be able to pull up the points.
Question 2:
When using Area AF, it appears that the camera is choosing some number of the points that would lie along a plane of focus and discards some number of points that do not. Is this a simplified explanation of the process?
Thanks!
Clint
