>Can someone explain me the story of stop down metering when using the >F2 photomic with an AIS lens?

There is none - they work fine together, same as non-AI (Unless you
mean the E, AIS 50mm f1.8, P 500mm f4, and AF lenses, which do not
have the little clip on the aperture ring at f5.6? If so, take the
lens off the body, press the coupling pin at the center bottom of
the meter head up into the head with a finger nail until you hear
two clicks. Mount the lens without the clip, and press the DOF
button while metering [release it before pressing the shutter
release]. Same thing works on F bodies, also.)
Hope This Helps
