I had the D800 and this lense for 2 years. It always works great until now, suddenly the auto Focus did not work? Is this the lense or Main D800? I checked the auto Focus menu and it's still intact , the lense ring just don't roll when I push haft way ? but works if I manually focus the ring?
Any ideas where I should check? or where I can bring my camera for checking? Help....please
Is it an AF-S lens? If it is then the focus motor is inside the lens, if it is AF-D then the focus motor is in the camera. MF-AF switch on lens set to AF?
It could also be dirty contacts on the lens or in camera.
