Some reviews on the net say D800 flash problems are inconsistent. Obviously not everybody has the problem I have. But I described the problem when I sent the camera to Nikon and they didn't fix it or say it was not reproducible. My description was condensed to "flash doesn't work" when they put the camera into their system.

I bought a 5D Mark III today. Not sure if I'll send the D800E back for another round of repair. I guess that would be futile unless I first get a human being on the phone to explain how the incompetent morons in his department altered the customer's problem report and mismanaged the service process so a 2-3 week job took 7 weeks. I was close to switching even if the camera came back fixed.
