Automatic diaphragm
OUT OF FOCUS
IN FOCUS
When the preview lever is in "AU¬
TO" (automatic) position, and the
exposure meter is turned to "OFF",
the fully automatic diaphragm is at
its largest aperture at all times, ex¬
cept for the instant of exposure, no
matter what aperture is set on the
diaphragm ring.
When you release
the shutter, the diaphragm automat
ically stops down to the predeter¬
mined aperture and the shutter cur¬
tains start traveling instantly. When
the exposure is completed, the dia¬
phragm reopens to maximum aper¬
ture completely automatically and
you are ready to compose, focus and
shoot your next pictures. If you wish
to visually check exact depth-of-field
before making the exposure, move the
preview lever to "MAN" (manual)
position.
This stops the diaphragm
to the aperture selected and shows
you exactly how much depth-of-field
will appear in your picture. The pre¬
view lever may be moved back to
"AUTO" (automatic) position before
or after making your exposure, or, if
you are making pictures in bright
sunlight, it may be left in manual
position, which permits a constant
check of depth of field.
*When the exposure meter switch is
turned to the "on" position, the lens
diaphragm changes from the auto¬
matic to manual position even though
the preview lever is in the "AUTO"
(automatic) position. When the shut
ter is released, the lens diaphragm
will automatically return to its au¬
tomatic position if the lever is set
on "AUTO".
