Can anyone explain how the 51pt AF works on a D300s? When the tab is set to 51pt, the AF point marker is gone, and there's no way to know what is focused.



No, I can't tell in the viewfinder what's in focus when it's dark and the subjects are moving. But with the other AF modes I can't focus and recompose a moving object. I switch orientation so can't use a side point.

I've always used the bottom 2 modes in the past.
