I've had my first DSLR, a Nikon D3300, for two years now. I originally bought it for bird photography with a used Sigma 120-400mm f/4.5-5.6 which has been quite enjoyable (despite the optical stabilization being incompatible with the firmware). About a year ago I bought a Tokina 11-20mm f/2.8 for a trip to the southwest and have been really enjoying landscape photography. I have a lot of 12"x18" prints that I'm happy with, but I would like to print at 24"x36" and larger, and the detail in RAW files from the D3300 just don't seem to cut it even at ISO 100. A bit more room for highlights and less shadow noise would be nice too.
Studio scene comparison, D3300, D750, D810, D850
I've looked at the D750 in the studio scene comparison and it seems a bit sharper than the D3300 but without really adding much detail (although it doesn't look artificially sharpened like the A7 iii either). I wouldn't expect to be able to print any larger from the D750. The D810 and D850 seem noticeably better than either even if you handicap them at ISO 400, presumably just due to resolution.
I don't expect a new camera to suddenly compose better photos for me, but I also don't want to end up with a heavier and more expensive body that I'm not getting value out of. When I bought the D3300 I had convinced myself that it was the sweet spot of price/performance and now that comes back to haunt me whenever I consider upgrading to full frame.
Do you think upgrading to a D810 or D850 is worth it? A used D810 would leave a reasonable lens budget. With the price of a D850 I would probably stick with my Tokina 11-20mm for now as it fills a full frame image circle at 16-20mm. I'm wary of spending more on a body and skimping on lenses though.
