There is NO electric stop-down mechanism in A, F, FA or even FAJ lenses. No
motors or solenoids exist in the lenses to close the diaphragm.
I remember that we had a discussion a while back about an aperture motor inside the FAJ lenses since Pentax seems to have changed the electrical protocol for the aperture, I don't think that we came to an absolute conclusion.
Best wishes Roland
