<p>I own a D810, previously D700 and think I may have two suggestions for you: First, as the pixel dimensions on the D810 are a lot smaller than the D700, care must be taken to use an appropriate shutter speed (higher) or mount on a tripod for less camera shake. Second, look into checking the micro focus calibration of all your lenses. Instructions are in the user's Manual or you can query online to find out how to accomplish this. Good luck!</p>
