I'm going to repeat some in between 24 and 70mm tests. Also and out of interest I am going to conduct the same tests on my D7000. I want to know if I need to worry that there's still a problem with the D800, but I really don't want to open that can of worms again. I have have posted my concerns on another forum:
"I must admit and I’m not trying to be controversial, but how did we ever survive without Lens AF-Fine tune! Until a year ago and the Nikon D800 left focus problems I’m willing to bet most photographers whether amateur or professional blissfully ignored fine tuning. Now everyone, me included, is having bouts of paranoia that their copy of a camera has focus problems, then testing it to satisfy their own fears and finding cause for concern"
