bright spot in my D300s viewfinder
It's visible on my D300. Don't see it on the D70.
It's most apparent when the central focus bracket is not highlighted.
I also have the small circle in the centre of my screen on my D300. As Steve says
it is only visible when the focus indicator is moved out of the way (I usually have mine set to use the central focus point).
