strange D800 focus issue
I have had my d800 for about a year now. It worked fine
until a couple months ago one of the nikon engineers told me my d800
needs to have its af module realigned.
The problem began after it came back from repair
For some reason, now the first few photos are always slightly front focused,
and as I take more shots, focus gradually returns to the correct position.
I turn off the camera for few minutes and turn it back on, it front focuses again.
I had the camera's mirror and af readjusted multiple times, but it hasnt eliminated
the weird focus shift. Now its back at the nikon service center, again.
I wonder if the whole mirror unit is faulty but really, I am just about to give up.
Is anybody familiar with this issue?
FYI my d800 has had its firmware updated during the first repair. any chance that might affect AF algorithm?
