>>3790290Thanks for the thoughtful reply. What's your insight into the difference between a D750 and a D610? The differences in low light performance between a D750 and D610 seem negligible to me, looking at test images and dxomark (pretty much every comparison is like this, no significant difference). For such a seemingly insignificant difference, I'd rather put the extra $3-400 toward a lens, since with the D610 I was planning to buy a 28-70 f2.8 VR, 70-200 f2.8 VR and 200-500mm VR. Either way, I'm planning to divest entirely of my DX camera and lenses. As for D780 and Z6, well outside of the range of what I want to spend on just a body.
