Nikon FE problem

Your description of the AI ring and the pin (tab) is correct.  What alarmed
me is that you mentioned that the ring is not in contact with the lens.  In
Nikon FE, the tab can be flipped up so that you can mount non AI lenses on
the camera.  If you mount an AI lens on the FE with the tab in the up position,
the ring will not be in contact with the lens.  The little button on the ring
locks and releases the tab.

In article ,  writes:
    I have a Nikon FE. There is a ring with a small metal pin just around
the outside of the bayonet mount. The pin on this ring comes into contact
with a ridge on the outside of the bayonet mount of the lens, so when you
move the aperture ring on the lens it moves this ring on the outside of the
camera bayonet mount.
    My problem is that sometimes the ring on the camera bayonet mount sticks
in place when I move the lens aperture ring counterclockwise. I am worried
that my exposure meter is not reading the right light reading when the ring
is not in contact with the lens. Everything seems to work okay anyway, but I
am not sure. I am wondering if the ring is only for older Nikon lens, to
link to the exposure meter in the FE.
    If anyone knows anything about this ring and its function I would
appreciate any information.
