- Like what you've got: stick with it. There's nothing particularly wrong with the D7500.
- Dislike what you've got: You have two basic choices: (1) move up to the DX Pro body (e.g. D500); (2) move up to FX.
Which should you do? Here's the simple guide:- Choose #1 if you're happy with what you've got in terms of camera and with DX in general but want to upgrade simply to update your equipment and get better body quality, autofocus performance, dual cards, and a faster top frame rate.
- Choose #2 (move up to FX, most likely the D780) if you're now serious enough that only the best possible image quality will do for your next camera. Be prepared to have to upgrade your lens set, too, though, especially at the wide angle end.
Wait, what, no mirrorless option? Not really. You'd be downgrading by buying the Z50. Thus, the only choice is to leave FX, which means Z5, Z6 II, or Z7 II.
