I can comfortably afford a used D7200, and with some stretching I could just swing a used D500 instead if I was convinced that it was worth the extra dough. I just not (yet) convinced. I figure I can get the D7200 used for around $600 USD and the D500 for about $1,100 USD. The function would be for wildlife/action shots, and perhaps macro work. I would continue with my full frame D610 for most other uses. I figure the autofocus on the D500 would most certainly be superior, as would the build quality, with amazing high ISO performance. The D7200 would have a few extra pixels (24M versus 20.9M) and I've heard that the image quality is perhaps a smidge better, but very close. Who has shot both- what would you do?
