Nikon repair service has now messed up the autofocus on both my D700 and D3 cameras after sending in the cameras for repair.
I sent in a backup D700 4 months ago because the rear panel near the screen required replacing. It came back a month or so later with back replaced but the white balance settings were all skewed to green(about +10-20 in Lightroom) so I sent it back. I would take pictures in all settings and images would appear way too green.
They fixed the issue but then I noticed the autofocus would not lock on. It would hover between slightly front focusing and then slightly back focusing. And do this all the time.
I tested the camera with 5 lenses(14-24, 28-70, 70-200, 300, and the problem persisted.
I just back my D3 from repair and a week later the same thing that happened on the D700 is happening. I have a D7000 and another D3 and they have no problems. The only problems happened after Nikon touched the cameras.
And charged $480.
What could Nikon be doing and why is this happening?
