Bill, looking again at the curves and reading your comments, would I be correct in assuming that DX mode with the D800, is liable to better better dynamically against the D700 in DX mode? I see the D800 in DX mode beats both the D700 and D7000 although not by a lot. I would be keen on a D800, but only if the DX mode could be utilised for wildlife.
Sorry to appear a bit daft, but I am trying to understand the curves and what they may mean to me in terms of the D800 in DX mode. I use FX for landscapes, portraits, architectural (so no issues there), but if the D800 DX mode can exceed the capabilities of the D7000 and if the DX element gives me equal or improved results against my current D700/D7000 then that interests me. Do you think that on paper the D800 with it's extra crop/pixels abilities will do the job well please?
Basically, if the D800 can equal my D7000 in terms of the photographic dynamic range in DX mode, then it will open up many previously unavailable opportunities all in one camera. If not much would be gained then I'll wait for a d300s replacement which was my original intention.
