AUTOMATIC EXPOSURE CONTROL
The Aperture-Preferred System
The aperture-preferred system
is the most convenient and
easy-to-use method of auto-
matic operation, particularly
outdoors when using 50mm or
wide-angle lenses. To use this system:
Set the selector lever to the "AUTO" position
making
sure
that
the
lever
"clicks"
into
place.
Set the F stop you wish to use on the lens
aperture ring.
The camera will automatically determine the
shutter speed required for proper exposure and
indicate that speed in the viewfinder. Then RE-
LEASE THE SHUTTER.
NOTE: At shutter speeds slower than 1/60 second,
the possibility of camera movement during ex-
posure is increased. If the needle in the viewfinder
indicates
a
shutter
speed
in
this
area,
turn
the
aperture ring to the left (so as to open the aper-
ture).
For use of interchangeable lenses of various angles
of view, refer to the data below to determine the
hand-held shutter speed and avoid blurry pictures:
Wide-angle and super wide-angle lenses — 1/30
second or faster. 50mm lenses — 1/60 second
or faster. Telephoto and Zoom lenses to
100mm — 1/125 second or faster. Telephoto
and Zoom lenses to 200mm — 1/250 second or
