The camera would attempt to stop down to wrong position, but since the camera would move its diaphragm lever *farther* than required, so the lens' mechanism would stop it at the correct point. That is, if the linear vs. geometric movement of the diaphragm lever is the way I think it is. -- Mark Roberts Photography and writing www.robertstech.com
