The pictures of this post have been sent to Nikon service. They reply me to send my D800 back for service: it would last max 5 working days. I already went through one service. I read online horror stories about 3 or more consecutive services ending tragically, with not a single AF bank at last calibrated.
As I could find a compromise with my D800 and the lenses I own, I do not want to risk. Unless you know of novel (after April 2013) Nikon guidelines for technical services on this D800 AF issue. Any news?
Click on each picture to magnify
L: left AF; M: middle AF; R: right AF; Lv: Live View; nAF: fine AF tuning value
red star: chosen setup
green point: as good as live view
orange point: acceptable but worse than live view
All picture open at maximum aperture, where the issue is mostly visible.
Pictures shot in different lights but also with (16-35mm) / without (50mm, 70-200mm) the last D800 firmware update (A 1.01, B 1.02): some yellow tint removed from jpeg format?
