APERTURE RING AND MANUAL SHUTTER SPEED RING
Aperture Ring
The opening (aperture) in the lens diaphragm is
marked in F stops on the aperture ring. The higher
the F number, the smaller the lens opening (less
light) and provides greater depth of field than
lower F numbers (see page 25).
When setting the aperture ring, you may use either
the click-stop positions or a n y in-between settings
to obtain precise exposure control.
NOTE: All lenses in the OM System (except cer-
tain specialized lenses) provide fully automatic
diaphragm control allowing you to focus and
compose your picture with the lens fully open.
The diaphragm will automatically close to the
pre-selected F stop at t he moment of exposure.
And immediately re-open after exposure.

Shutter speeds engraved on the manual shutter
speed ring are used only for non-automatic camera
operation. B indicates

CAUTION: Do not advance the film while
the mirror is up during an automatic exposure,
or the mirror will lock up.
The Shutter Speed-Preferred System
Should you wish to select a shutter speed to meet
a specific photographic situation (e.g., stopping
fast action, eliminating camera movement or controlling depth-of-field), you may use a shutter

HOLDING THE CAMERA
Proper camera handling is important in assuring
the sharpest possible pictures.
Holding the Camera Horizontally
Keep both elbows close to the body, to steady
the camera.
Putting the Camera into Operation
The aperture ring, focusing ring and shutter speed
ring are so arranged as to enable one hand opera-
tion right up to the moment the shutter is released.
Hold your breath at the moment of shutter release.
Transport the film advance lever with your right
thumb and squeeze the release button smoothly
using the cushion, not the tip, of your index
finger.
Holding the Camera Vertically
For vertical shooting, keep one elbow close to
your body and press the camera tightly against
your forehead.
NOTE: Steady yourself against any nearby sup-
port (such as a tree, fence, or wall) whenever pos-
sible.
NOTE: For telephotography, or slow shutter
speed photography, it is recommended th at yo u
use a tripod and hold the camera steady with
your hands.
19
UNLOADING THE CAMERA
When t he entire roll of film has been exposed re-
wind th e film.
Turn the rewind release lever counter-clock-
wise by about 90°.
Fold out the rewind crank and wind it in the
direction of the arrow. Wh ile rewinding, yo u
will feel tension on the crank. When the ten-
sion stops and the crank turns freely, th e film
has been completely rewound back into the
cartridge.
Open the camera back by pulling up on the
rewind knob and remove the film cartridge.
Keep camera and film out of direct sunlight
while unloading.
MAKING MULTIPLE EXPOSURES
Should you wish to make more than one exposure
on the same frame:
Take up any slack in the film by slowly turning the rewind crank in a clockwise direction
until it stops, then take the first exposure.
Turn the rewind release lever counter-clock-
wis e by about 90°.
Hold both the rewind knob and rewind release lever to prevent them from turning and
advance the film advance lever. The shutter
will then be cocked for the next exposure
without advancing the film.
Press

After completing the multiple exposures, put
the lens cap on the lens, advance the film, and
shoot a blank fram e to avoid overlapping.
NOTE: You can make as many multiple exposure
as you like by repeating the above procedure. With
each exposure on the same frame, the possibility
of slippage is increased.

You may set the self-timer lever either before
or after advancing the film.
Turn the start lever clockwise to the vertical
position to activate the self-timer lever. The
shutter will then be released after the preset
time.
Stopping the Self-timer
To stop the self-timer during its operation, turn

When the most im-
portant area of the picture is much darker than

brightest part of the picture leaving the main subject under-exposed. Alternatively, when taking a
picture of a bright subject against a dark background the meter tends to read the darkest part

leaving the main subject over-exposed. In these
situations, proper exposure compensation helps
you take fine pictures.
NOTE: With backlighting or sidelighting it's al way s a good idea to use a lens hood to eliminate
unwanted glare.
22
EXPOSURE COMPENSATION FO R AUTOMATIC MEASUREMENT
If you wish to change the exposure setting auto-
matically selected by the camera, use the exposure
compensation dial and a compensation marker
appears in the viewfinder.
Whe n the main subject is much darker than the
general background or when strong light strikes
the subject from behind or from the side, turn
the dial t o the ( + ) side.
Turn the camera to the subject so that the subject
fills most of the viewfinder, or move the camera
toward the subject. After reading the shutter
speed, return to the original position and rotate
the compensation dial until the meter needle
points at the read-out speed in the finder.
NOTE:
In

When taking a picture of a bright subject against
a dark background (spotlightng, deep shadows,
etc.), turn the compensation dial to the (—) side.
Move forward until the subject fills as much of
the viewfinder as possible, (with a zoom lens, you
may be able to do this by zooming in on the subject without chaning your positions). After
noting the shutter speed indicated by the meter
needle, return to your original position, recompose
the picture, and turn the compensation dial until
the shutter speed needle indicates the speed obtained from your close-up meter reading.

EXPOSURE COMPENSATION FOR MANUAL MEASUREMENT
1 Stop Over
Manual exposure can be compensated by adjust-
ing the F stop or shutter speed. The exposure
needle indicates over-exposure at the (+) side, or
under-exposure at the (—) side.
Dark subject in bright backlighting
When the most important area of the picture is
much darker than the general picture area (strong
light hitting the main subject from behind or from
the side) the meter will have a tendency to read
the brightest part of the picture leaving the main
subject under-exposed. To compensate for this,
move forward until the subject fills most of the
viewfinder picture area and set the F stop/shutter
speed combination which centers the meter needle
between the index marks. Return to your original

DEPTH OF FIELD
F1 6 , 1/1 5 sec.
F2, 1/1000 sec.
Depth of fi eld is the a rea of acceptable sharpness
in front of and behind the subject in focus. As
you get closer to your subject or as you open your
lens (e.g. from F16 to F2.8) the depth of field
becomes shallower. By stopping your lens down
(e.g. from F2.8 to F16) or getting farther away
from your subject this depth of field can be increased.
The table below shows that when the camera-
to-subject distance is 3m, the depth of field at
F16 ranges from 1.93m t o 6.93m.
As you

DEPTH OF FIELD SCALE
PREVIEW BUTTON
The double series of numbers engraved on the
depth of field scale represents F stops: F4, F8,
and F16. Once you have focused on your subject,
all objects within the distance range indicated
on the lens distance scale between the marks for
the F stop yo u have selected will have acceptable
sharpness. For example, in the above picture, t he
camera-to-subject distance is 3m (10ft.) and the
lens is set at F16. If you read the distance scale
at the points opposite the engraved "16" on both
sides of the refere nce dot, you will find that the
depth of field is from 1.9m ( 6f t. ) to 7m (23ft.).
When you wish to see which objects fall within
