Just got my D810 back from Nikon repair for a USB port problem. The camera was reset completely, including all my settings, date, etc. It has the latest firmware.
After doing my usual setup, I used my spyder lenscal to tune the focus. The adjustment on my Nikkor 24-70 2.8 needed a +4 before the repair and now, +18. Same on 5 other lenses including 3 sigma art primes and a Nikkor 70-200 2.8. I know the body quite well, but just wondering if there is something obvious I am missing here. My D750 body needed some adjustment on a few lenses, but not in the same ballpark.
