Len, if I'm reading your post correctly, you have an amazing array of lenses. I thought I had too many with 10 of them.
Poll is updated.
After more testing, I have found a frustrating trend.
A coup,e of my lenses clearly benefit from fine tune at +10 or +15 at f1.4, but by the time they are at 2.8 or 3.2, the tune has the opposite effect, causing back focus.
So the tune is only good at wide apertures. This is nuts.
Meanwhile my 105 2.8 VR is dead on without any tune.
This lack of precision is a real concern with the D800 because it is so revealing.
No wonder Nikon published a technical manual on how to get sharp pictures before the camera was even released. The key they advise is focusing with magnified live view. Perhaps the reason they recommended that is the autofocus system of their camera and lenses is not reliably up to the task.
Anyway, my results so far:
85 1.4G..+15 .at f1.4-f2.2.... 0 after 2.8 24-70 +10 at all apertures 50 1.4 g .l.l+10 at 1.4-2.0 or so, 0 after 2.8
