Argus cosina 704 - Automatic-Manual Exposure Control; Using the Control Dial; Filming in AUTO Mode; Manual Exposure Setting

AUTOMATIC
-MANUAL
CONTROL
The electric eye exposure control takes power from the battery only
when the EXPOSURE CONTROL DIAL isin the AUTO or MANUAL
position. When the camera is not in use move the EXPOSURE CON-
TROL DIAL tothe OFF position and the circuit is then automatical-
ly off to conserve power. If a fresh battery is needed your Argus dealer
can supply you with the proper replacement type (MALLORY PX-
13, EVEREADY EPX-13, BURGESS HPX-13, or equivalent.)
Set EXPOSURE CONTROL DIAL to AUTO position whenever you
want to use the automatic exposure control system. When set on
AUTO, the camera’s lens opening will automatically increase and de-
crease, while you are filming, continually adjusting for correct ex-
posure in all suitable light conditions. ‘‘Suitable’’ conditions exist
whenever the EXPOSURE INDICATOR in the VIEWFINDER shows
any area of the aperture other than the red warning zone. If the red
warning zone is visible at the exposure indicator marker, there is in-
sufficient light for correct exposure and you should stop filming.
The lens opening being set by the electric eye (f 1.8 to f 22) is
always visible in the viewfinder when the EXPOSURE INDICATOR
is set on AUTO.
