Some test shots on the Sony A900 and the Nikon D800. I tried to keep the f-stops etc. in synch, which wasn't always possible. Lenses used:
Sony - Zeiss 16-35 f2.8
Nikon - 20mm f2.8 MF & 35-70 f2.8 (good copy!)
(It would have been nice to have the 85mm f1.4 for both systems at my disposal, but that was not feasable)
Files 3 to 14 were all converted from ARW or NEF with LR4, processing engine 2012. All values were left at zero (as is the default on P2012 in LR4), no sharpening. WB was left the way it was recorded, except on files 13 &14, where the Sony file was "lifted" to exactly match the WB and Tint values of the native Nikon NEF.
Note that 16 is a high ISO demo shots on the D800. 15 is an unaltered JPG of an acquaintance. #20 serves as a form of "color chart" for D800 color palette (not authoritatively of course).
Images 5 & 6 were underexposed on purpose by 3 stops to see what can be pulled up from the respective files in post.
Images 19 following are the ones which have undergone some type of real processing, and should be considered close to the "finished product".
