OK, that's clear ... so what does the aperture reporting pin do John?
And how does it (what it does) differ between auto and manual lenses?
Stinkin' inquiring minds, you know the score!

Coupling pin will only affect manual metering. OTF auto don't need no
stinkin' pins.

Is this really so? I thought the great beauty of real-time OTF
metering was that it simply integrates the light received by the film,
and closes the shutter when it's done (or quenches the flash if one is
attached). It shouldn't matter about coupling pins or anything else in
auto mode. Manual metering - that's another story!
Am I right? Perhaps John H could chip in with his wisdom!
