I have not taken image shots with the D800E yet. I am still doing AF fine tuning with all of my lens and aperture sharpness testing. So far with three lens I am getting an average of 50% higher QoF with each lens than I am getting with the D800. Not sure what this means in an absolute sharpness of image measure. Someone with more MIPS than me will have to answer that question.
The AF fine tuning settings are coming out at about the same between the two bodies...good indication of mount consistency.
The tests on my 70-200mm have confirmed that VR does not work right. I am getting exactly the same scatter of points for both bodies when doing AF fine tuning with VR turned on but not when I turn it off. Huge difference.
Having two D800 bodies side by side show the clear consistency of FoCal testing because all settings are the same and all target conditions. It just comes down to the difference in the camera sensors.
If FoCal did not fail so much when doing the AF fine tuning, the testing would go faster. About 20% of the time the software goes off calculating at the very end of the AF fine tuning and never finishes the calculating. The predicted AF fine tuning adjustment is good based on subsequent testing, but it just does not finish. The developer is really insulting buyers by leaving this bug in the software.
