Hi,

Been trying to understand the compatibility issues of nikkor lens/
nikon camers.

Say I have a Nikon f2as DP-12 finder. If I use a pre AI lens it would
work but I would have stop-down light metering?

Yes. At least I think so. I have an F2AS, but no pre AI lenses. The
finder allows you to flip up the AI metering tab so as to mount a pre AI
lens without damage, but has no prong to be captured by the pre AI
lens's metering fork to tell the camera what aperture has been pre-set
on the lens.

But if I used a pre-AI lens on a Nikon F Photomic then the metering
would be that the lens would be largest F-stop until I shoot? Or would
it be stop-down as I meter?

I think the former - since I believe the F's Photomic finder (and some
older finders has the necessary prong that the F2AS lacks (but I've
never owned an F)

What would hapen if i put a Photomic finder on the F2as body?

The DP-12 finder that makes an F2 an F2AS is also described as a
Photomic finder. But if you mean one of the Photomic finders designed
for the F, then my first guess would be that you would break one of
them... probably the finder, because it would be hard to break an F2 body.

...but the pre-AI could be serviced to make it AI?

Yes, if you can still find someone to do it.
