“Just got my D800E back from NPS. Apparently, the cause of the focusing problem in all cases is some inaccurate calibration data entered during the alignment/ calibration process. I was told it’s basically a case of hooking the camera up to the laser calibration jig, and letting a piece of software run a calibration routine point by point – there are no physical or mechanical adjustments made to the camera. The software then writes this somewhere in the camera’s ROM for future use.”
There are also several other D800/D800E asymmetric focusing problems online. We guess a official firmware update will be released soon.
