DX versus FX, crop vs full frame: it's a question that's been on many shooter's minds since the dawn of the so-called "affordable" full frame era. It's a false dichotomy, really. There's no question that full frame is better but the dilemma for many is whether or the cost can be justified. If you are being paid to do photography, even if it's the odd weekend wedding gig, then the answer is easier to arrive at: go with full frame, because that is where most of the competition is already at.
For the non-professional shooter, Nikon has moved the goalposts since the D7100/D6100 era. The D7200 and the D750 are both extremely capable cameras, but the value proposition has been altered somewhat. The D600 (and D610) were designed to be extremely easily "step-up" solutions for DX users: they were more or less the same camera, but with upgraded sensors. Comparatively, the D750 is more when compared to the D7200.
- Comparatively slimmer body
- Group Area AF
- Higher resolution exposure meter
- Additional highlight priority spot metering
- Power aperture control during video and live view
Because of these additions, the gap in price between the two tiers has increased. Ordinarily, this would discourage some shoppers from looking at the more expensive option, but the situation is made less clear by the apparent lack of interest Nikon has given the serious DX market in recent years.
