Maybe it is just me, but I was surprised at how close the D500 and D7200 noise compared in the DP Review link. I expected a bigger improvement and I did not see that much difference. That is JUST MY impression.
I didn't read the review yet, but I take it that if one doesn't care about the improved focusing, the higher frame rate/buffer and the auto fine tune capabilities, then there is no reason to make the jump from the D7200.
I still want one, but I just can't part with my D750. I would have to sell her off plus sell off the D7100 plus a few other lenses to afford this magnificent beast.
