Hi Justin If you've not used a D500 before I think you're going to be impressed. However, as you were actually looking at spending a couple of grand on a Sony body then you could probably do worse than seriously consider the D850. Compared to the D750 the D850 has Touch screen, Focus Peaking, Higher resolution, Focus Stacking, ISO 64, superior AF system, better ergonomics with a more comfortable grip etc. Plus you've also got the option of using it full frame and cropping if necessary or using it in DX mode. Apparently it also works superbly with the new 70-200mm lens (think you've still got yours?). Just waiting for my D850 to arrive and got a rather good deal from Panamoz for the body and grip.
