There is no pin pushing. The pin on the adapter is in a fixed position
and simply forces the Zuiko into a pre-set mode where the aperture opens
and closes as you turn the aperture ring. In the third photo on right
in this auction the stop-down pin is the small, copper, L-bracket at
about the 9:30 position.

As to the vagaries of metering in stop-down mode on EOS thingies you'll
have to ask Moose or someone who actually owns one. I don't own one yet
but hope to try this adapter on a 20D tomorrow.
