I wonder what advantage there is in programming the AE-L/AF-L to AF-ON. I do not have a D7000/ D7100; either, I have a D5100 that I programmed the button for AF-ON. When I press the button, it focuses, but to engage VR, I have to depress the Shutter Release half way. My D200 has a dedicated AF-ON button and it works the same as the D5100. Why not just depress the Shutter Release half way?
Is there some advantage to the AF-ON that I don't know about.
