Thanks for that write-up Woody. Very helpful.
One thing you don't mention is the U1/U2, or lack of on the D500, do you utilize this feature on your D7100 & D7200 ?
I know the D500 has some sort of memory banks, but from what I can figure out, it is Probably not as good as the User settings I use and like very much on my D7100.
I never used the User Settings of either the D7100 or 7200 myself. I'm finding manual mode with auto-ISO and judicious use of exposure control is the easiest/best set up for virtually everything I do. Obviously, this is an individual preference thing. If you are using the U1/U2 all the time, I imagine you might miss it. I've never messed with figuring out the memory banks, so I have no opinion there. Sorry.
