Ah, you are asking the $400 question, which I have not been able to
answer (Shutterbug has accepted an article proposal on this, and most
of the article is written, EXCEPT the nitty-gritty part, which I regularly
do, but find difficult to explain). My guess is that everything is OK
on the body (just try everything on film, and keep track of what you did),
except maybe focus (manual and AF) - try shooting deep subjects at wide stops, see if VF/AF focus agrees with film focus. For lenses, see if all four corners of a distant subject are equally sharp at f5.6 with the
focus locked (at various FL's - though refocus at each new FL, since
most Nikkor zooms do shift focus a bit with zooming).
