Folks...I am baffled. After overnighting the D800 to Nikon on 7-30, I finally hear from Nikon that there was no "ERR" message and they intend to return it "after cleaning". It was 2 months new and did not need cleaning. Per Nikon "even the error log on the camera did not show an "ERR" message. How can this be? I am absolutely sure, after field and on-line with Nikon trouble shooting, that the "ERR" message was there.
Nikon Customer Services support asked if I would ould I send my 14-24 lens, battery, and memory cards to Nikon overnight. That is fair, but inconvenient.
I did send it yesterday and am waiting on pins and needles for their determinatinon.
