Will going full frame have better transitions between shadows and highlights?

[CreeDo]

A 1.5 crop sensor does not give 1.5x the focal length - it gives a field of view that is (1/1.5x) the width of FOV of the same FL lens on a FF sensor. Its FOV is therefore the equivalent of the FOV from a lens of 1.5x longer FL when used on FF, but that's not the same as actually having a longer FL.

Is that just splitting hairs, or is there a practical difference between
"having 1.5x the focal length" and
"the FOV looks the same as a shot taken with a lens that had 1.5x the focal length"?

The difference is, one statement is true and the other isn't. Other than that, they're the same.

Given a choice, I prefer to make statements that are true.

I used a 24-70, 70-200, and a 85mm 1.4, so I doubt that the glass is the case

You can infer a lot about other aspects of FX vs. Dx from this little graphic while you wait on a site Garoo to answer your primary question although I would say to trust your own eyes. A D750 would be a wonderful addition to your kit.

You can infer most equivalency precepts from this graphic.

Rick Knepper, photographer, shooting for pleasure. I use tools, not brands. It is better to have It and not need It than need It and not have It. Mystery Gardner: "Rick, you have a passion for photography but not a position. That's a good thing." Based on 2014 keepers, I shot the following percentages: 5D3=42%, D800=31%, 6D=25% & D3x=2%. Various RAW comparisons at Link below. Now includes 645Z files, 5D3 vs D800E, 5D3 vs. 6D, Zeiss lenses etc. https://app.box.com/s/71w40ita6hrcfghojaie
