Automatic diaphragrri OUT OF FOCUS ), IN FOCUS When the preview lever is in "AUTO" (automatic) position, and the exposure meter is turned to "OFF", the fully automatic diaphragm is at its largest aperture at all times, except for the instant of exposure, no matter what aperture is set on the diaphragm ring. When you release the shutter, the diaphragm automatically stops down to the predetermined aperture and the shutter curtains start traveling instantly. When the exposure is completed, the diaphragm reopens to maximum aperture completely automatically and you are ready to compnse, 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 preview 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 automatic to manual position even though the preview lever is in the "AUTO" (automatic) position. When the shutter is released, the lens diaphragm will automatically return to its automatic position if the lever is set on "AUTO". 12

OUT
OF
FOCUS
IN
FOCUS
When
the
preview
lever
is
in
"AUTO"
(automatic)
position,
and
the
exposure
meter
is
turned
to
"OFF",
the
fully
automatic
diaphragm
is
at
its
largest
aper-
ture
at
all
times,
except
for
the
instant
of
exposure,
no
matter
what
aperture
is
set
on
the
diaphragm
ring.
When
you
release
the
shutter,
the
diaphragm
automatically
stops
down
to
the
predetermined
aperture
and
the
shutter
cur-
tains
start
traveling
instantly.
When
the
exposure
is
completed,
the
diaphragm
reopens
to
maximum
aperture
completely
automatically
and
you
are
ready
to
compnse,
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
preview
lever
may
be
moved
back
to
"AUTO"
(automatic)
position
before
or
after
making
your
exposure,
or,
if
you
are
making
pictures
in
bright
sun-
light,
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
dia-
phragm
changes
from
the
automatic
to
manual
position
even
though
the
pre-
view
lever
is
in
the
"AUTO"
(automatic)
position.
When
the
shutter
is
released,
the
lens
diaphragm
will
automatically
return
to
its
automatic
posi-
tion
if
the
lever
is
set
on
"AUTO".
