AF: that may be the most relevant aspect of this new camera. Have you tested the various points. Since its sensor is denser than the D800's and I have seen some problems with PDAF for extreme lateral points (mostly the leftmost AF point), I wonder if you have checked that.

If there are problems with PDAF at the extreme lateral AF point, that shouldn't have anything to do with the sensor density since the AF sensors are located off-sensor, below the mirror box IIRC. No?

Thanks for the good job, rather fast!

Yes, excellent job. If Thom Hogan needs to hire another assistant ...

YOu forget that people check AF accuracy at full res. The D7100's full res is 50% higher (pixels per unit area) than the D800's. What was ok at 12MP (D700) seems not to be ok at 36MP, the D7100's sensor density at FF would provide 54MP worth of pixels.
