For example, if you really like what you do with the D200, then the D500 is logical. I'm not a fan of FX as such, but I still prefer to have a more mobile DSLR, but there are other considerations, better results, a greater degree of DOF. Switching to FX changes many variables for you. For a close-up, I'll transfer it to the D750, but that's all, perhaps, add landscapes with an average DOF. For me, the D500 is best suited, but you have to look at the samples and, of course, test them.
