In aperture priority mode, difference should be that aperture control
arm always travels the full distance. Maybe because program f stop lock
(controlled by another electromagnet) is not at play, overall sound of
the camera may change. This f stop governor is always in play and this
is why maximum speed with motor drive is limited to about 3 fps.
