speed at which the ISO sensitivity automatic control starts to function
(1/125 to one second) is set. The default setting is None. If the exposure
is insufficient with the shutter speed that is set here, the ISO sensitivity is
increased automatically to obtain the correct exposure. If the exposure
is still insufficient even after the ISO sensitivity is increased, the shutter
speed slows down.
