4. Advance the film.
Advance the film using the film ad-
vance lever, Make sure that the film
perforations engage on the sprockets
on both sides.
5. Close the rear cover.
Close the rear cover until it clicks into
place.
6. Tighten the film.
After closing the cover, fold out the
rewind crank and turn it slowly in a
clockwise direction until a slight resist
ance is felt. This will take up any slack
in the film
7. Check the exposure counter win-
dow.
Advance the film and depress the
shutter release button, Advance the
film once more until “17 appears in
the exposure counter window. The
rewind knob will rotate in a counter-
clockwise direction indicating that the
film is advancing properly.
2 UNLOADING THE FILM
When the entire roll of film has been
exposed (indicated by numbers 12, 20
or 36 on the exposure counter depend-
ing on film length), rewind the film.
1) Turn the rewind release lever coun-
ter-clockwise until the red tine 15
opposite the "R"".
H MAKING DOUBLE EXPOSURES
Should you wish to make more than
one exposure on the same frame,
1) After taking the first exposure, turn
the rewind knob slowly in a clockwise
direction until it stops to take off any
ack In the film.
Turn the rewind release lever coun-
ter-‘tockwise until the red tine is
conaosite the "RL
2) Fold out the rewind crank and
wind it in the direction of the arrow.
During the rewind procedure you will
feel tension on the crank. When it
turns free the film has been completely
rewound back into the cartridge.
3) Hold both the rewind knob and
rewind release lever firmly to prevent
them from turning and advance the
film advance lever. The shutter will
then be cocked for the next exposure
of the frame, without the film being
advanced.
4} Depress the shutter release button
with a slow, steady pressure.
5) After completing the muitiple ex-

3) Open the rear cover by pulling up
on the rewind crank and remove the
film cartridge. Keep camera and film
out of direct suntight.
IMPORTANT: Do not force the film
advance lever ¡f the film has been fully
exposed. If there is some resistance,
rewind the film to prevent tearing.
posure, cover the lens with a lens cap,
advance the film and shoot a blank
frame to avoid overlapping.
You can make as many multiple ex-
posures as you like by repeating the
above procedure. With each exposure
on the same frame, however, the likeli-
hood of slippage is increased. Practice
IS required in order to obtain good
results.
SETTING THE SHUTTER SPEED RING X SETTING THE APERTURE RING
De
The length of time that light is allowed
to strike the film is controlled by the
focal plane shutter. The shutter con-
sists of two .opaque “curtains” which
travel across the opening and allow
light to reach the film. The speed and
coordinated movement of these cur-
tains determine in fractions of a second
the exposure time for your picture.
For example, 1000 on the shutter
speed ring indicates 1/1000 of a second
and 60 indicates 1/60 of a second. The
figure 1 indicates one full second. The
B (Bulb) setting is used for longer time
exposures. At this setting the shutter
will remain open as long as the shutter
release button is held down. For ex-
posures less than 1/30 of a second, it is
advisable to use a cable release, tripod
or other steadying devices to avoid
camera movement which can result in
blurred or fuzzy pictures.
To set the shutter speed turn the
shutter speed ring in either direction
until the desired number clicks into
place opposite the reference dot on the
lens barrel. Set the ring only at click-
stop positions as no in-between settings
can be used. Shutter speeds may be set
before or after advancing the fiim.
NOTE: Speeds from “B” to “60” are
indicated on the ring in blue as an easy
reference to X” flash synchroniza-
tion.
The amount of light allowed to strike
the film is represented by ‘F' numbers
or "'F’ stops engraved on the aperture
ring. The higher the F number, the
smaller the lens opening (less light); the
lower the number, the larger the lens
opening (more light). When setting the
aperture ring you can use either the
click-stop positions or any in-between
settings to obtain precise exposure.
All lenses in the OLYMPUS OM-SYS-
TEM (other than specialized lenses)
provide fully automatic diaphragm
control allowing you to focus and
compose your picture with the lens at
maximum aperture or “wide open.”
The diaphragm will automatically stop
down to the preselected F stop at the
moment of exposure and immediately
re-open when exposure is completed.
Setting the correct ASA film speed on
the camera is one of the most impor
rant factors in determining exposure.
in order to obtain properly exposed
pictures, the correct ASA film speed
must be set on the ASA film speed
dial. To set the dial:
1) Pull the film advance lever slightly
away from the camera body.
2) Press the film speed dial release
button and turn the film speed dial
until the ASA rating for the film being
used is opposite the black line engraved
on the outer ring of the shutter release
button.
1) Release the button making sure
that the dial is securely in place and
does not move,
The OLYMPUS OM-1 incorporates a
built-in, wide-open exposure metering
system which uses two highly-sensitive
CdS cells with one positioned on each
side of the eyepiece. These cells meas-
ure the actual amount of light entering
the lens, placing the greatest emphasis
at the center of the picture area.
Measurements are taken with the lens
diaphragm at maximum aperture {wide
open) allowing you to take full ad-
vantage of a brighter viewfinder when
focusing and composing your picture.
The OM-1 metering system operates as
above with all OM-System camera
lenses regardless of the focal length,
filters, etc.
e SETTING THE EXPOSURE
Ш Activating the Meter
The OLYMPUS OM-1 metering system
is directly coupled to the shutter speed
ring, aperture ring and ASA fitm speed
dial,
To activate the meter, move the meter
switch lever at the top of the camera to
the “ON” position. To prolong battery
life, it's a good idea to return the lever
to the “OFF” position when the cam-
era is not in use.
M Preselecting the Shutter Speed
Should you wish to select a shutter
speed to meet a specific photographic
situation (for example, to stop fast
action, eliminate camera shake, etc.):
1) Turn the shutter speed ring until
the desired speed ts opposite the red
reference dot on the camera lens.
2) Look through the viewfinder and
turn the aperture ring until the needie
lines up tn the center of the index. For
fine exposure adjustment you can use
any intermediate F stop position on
the aperture ring.
3) If the needle will not align proper-
ly, select a new shutter speed. To
correct over-exposure (+), try a faster
speed; to correct under-exposure (—),
try a slower speed.
Exposure Meter Needle |
Exposure Meter index
H Preselecting the F Stop
Should you wish to preselect the F
stop (for example, to control depth of
field for greater creative impact):
1) Turn the aperture ring until the
desired F stop is opposite the white
index mark at the front of the lens
barrel.
2) Look through the viewfinder and
rotate the shutter speed ring until the
needle lines up as close as possible to
the center of the index. Make sure that
shutter speed meets the other require-
ments of the situation.
3) Make the final exposure adjustment
by turning the aperture ring slightly
until the needle aligns exactly in the
center of the index.

MN Making Intentional Over- or Under-
exposures
You can make intentional over- or
under-exposures to meet special light-
ing requirements (such as backlighting,
sidelighting, etc.) by using the central
index in the viewfinder as a guide.
When the needle swings towards the
{(+) position, it indicates over-exposure.
When it swings towards (—), it in-
dicates under-exposure. The exact F
stop-needle relationship is shown in the
above diagrams.
E Automatic Low Light Level and
Meter “OFF” Warning
When the meter switch lever is "OFF"
or when the light is insufficient to
produce proper exposures, a warning
switch automatically closes a circuit
causing the needle to move entirely out
of the viewfinder index. This warning
switch does not function if the battery
is not inserted properly in the camera.
Ш Stop-down Exposure Readings
When using the OM-1 in conjunction
with extension tubes, bellows or the
Zuiko Shift Lens it is necessary to take
meter readings with the lens stopped-
down. After setting the desired aper-
ture on the aperture ring, stop the lens
diaphragm down and look through the
viewfinder. Rotate the shutter speed
ring until the needle aligns within the
center of the index. (See the instruc-
tions on Preselecting the F Stop, page
13.)
M Special Exposure Techniques
1) Backlighting and Sidelighting
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 in
towards the subject until most of the
subject image appears in the viewfinder
and take your meter reading. After
setting the exposure, return to your
original position to take the picture. If
this procedure cannot be followed, you
can obtain approximately the same
results by simply opening your lens
one full F stop over the indicated
meter reading. (NOTE: With back-
lighting or sidelighting, it's always a
good idea to use a lens hood to
eliminate unwanted glare.)
2) Strong Frontlighting and Deep
Shadows
When taking a picture of a bright
subject against a dark background
(spotlights, deep shadow areas, etc.)
the meter has a tendency to read the
darkest part of the picture leaving the
main subject over-exposed. To com-
pensate for this use the same procedure
for setting exposure as outlined for
backlighting. You can also approxi-
mate the proper exposure by holding
your position and closing the lens
down one full F stop from the indi-
cated meter reading.

= FOCUSING
ь | =
The OLYMPUS OM-1 comes equipped
with a standard microprism-matte type
focusing screen which is designed to
make focusing quick and easy. To
focus, look through the camera view-
finder and turn the focusing ring in
either direction until your subject
appears sharpest. The ‘shimmering
effect” of the central spot in the
focusing screen will disappear when
critical focusing has been achieved.

EX INFRARED PHOTOGRAPHY “DEPTH OF FIELD SCALE PREVIEW BUTTON
The OLYMPUS OM-1 provides an infra-
red index mark engraved in red on the
depth of field scale to the right of the
reference dot. When shooting with
infrared film, focus normally on your
subject and read the subject distance
on the distance scales. Then, turn the
focusing ring to the right until the
distance reading is opposite the infrared
index line. Your lens will then be In
focus for average infrared photography.
In the above picture the red index is
set at infinity.

E Ea IO LA MB ma, те =
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 subjects
within the distance range indicated on
the lens distance scale between the
marks for the F stop you have selected
will have acceptable sharpness.
For example, in the above picture the
camera-to-subject distance is 3m (10ft)
and the lens is set at F16. {f you read
the distance scale at the points op-
posite the engraved ‘16’ on both sides
of the reference dot, you will find that
the depth of field is from 1.9m (6ft} to
7m (23ft). The depth of field can be
visually verified by pressing the depth
of field preview button.
When you wish to see which objects
fall within the acceptable zone of
sharpness (depth of field), press the
preview button on your lens. The
diaphragm of the lens will stop down
to the preset F stop enabling you to
see the depth of field in the camera
viewfinder.
2 DEPTH OF FIELD
Depth of field is the area of acceptable
sharpness in front of and behind the
subject in focus. This depth is deter-
mined by the F stop you have selected
and the distance from the subject in
focus to the film plane. As you get
closer to your subject or as you open
your lens (e.g. from F22 to F2.8) the
depth of field becomes shallower. By
stopping your lens down (e.g. from
F2.8 to F22) or getting farther away
from your subject this depth of field or
zone of acceptable sharpness can be
increased.
Another factor in determining depth of
field is the focal length of your lens. As
a rule the shorter the focal length, the
greater the zone of acceptable sharp-
ness. The longer the focal length, the
shallower this zone becomes.
The table above shows that when the
camera-to-subject distance is 3m (10ft),
the depth of field at F16 ranges from
1.293m (6ft) to 6.93m (23ft).

eE HOLDING THE CAMERA
Proper camera handling is important in
assuring the sharpest possible pictures.
Even slight camera movement can re-
sult in “blurred’’ photographs. To hold
the camera properly, support the cam-
era/lens combination with most of the
weight resting in the palm of your left
hand, while applying your right hand
to the camera's side. 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. The aperture ring,
focusing ring and shutter speed ring are
so arranged as to enable you one hand
operation with left fingers right up to
the moment the shutter is released.
Hold your breath at the moment of
shutter release.
x When holding the camera hori-
zontaliy, keep both elbows close to the
body.
X For vertical shooting, keep one
elbow close to your body and press the
camera tightly against your forehead.
x Steady yourself against any nearby
support (such as a tree, fence, or wall)
whenever possible.
*x When hand-holding a telephoto
lens, camera shake is magnified as the
focal length increases. Always try to
use the fastest possible shutter speed
lighting conditions will allow.
x When shooting under 1/30 of a
second, using a stable platform or
tripod with a cable release is recom-
mended. This eliminates the possibility
of jarring the camera and is particularly
important with telephoto lenses.
B® SETTING THE SELF-TIMER
The self-timer provides a method of
taking delayed action pictures allowing
you to get into your own photographs.
It is also ideal for macrophotography
when a cable release is not available.
To set the self-timer:
1} Rotate the self-timer lever counter-
clockwise until it stops (approximately
180°). Make sure the film has been
advanced properly.
2) Turn the start lever clockwise to
the vertical position to activate the
self-timer lever. The shutter will then
be released in approximately 12 sec-
onds. You can adjust the delay time
between four and twelve seconds by
adjusting the lever as shown above.
If the film has not been advanced
properly, the timer lever will stop
halfway and the shutter will not fire.
To re-activate the timer, move the start
>t LOCKING UP THE MIRROR
lever counter-clockwise to stop the
timer lever, return the timer lever to
the starting position, and advance the
film. Then, turn the start lever again.
NOTE: If you do not reset the self-
timer, the timer lever will begin moving
immediately after advancing the film
and the shutter will be released earlier
than expected.
You may set the self-timer lever either
before or after advancing the film.
Even after setting the lever, you can
release the shutter by pressing the
shutter release button. To stop the
sel f-timer during its operation, turn the
start lever counter-clockwise.
To minimize camera vibration in close-
ups, reproduction work, macro-
photography and photomicrography,
you can lock the instant return mirror
in the up position to eliminate mirror
shock. This is also handy in rapid
seguence shooting. To lock up the
mirror, compose and focus on your
subject and then turn the mirror lock-
up lever counter-clockwise until it
stops (approximately 90°). After
shooting, always return the lock-up
lever to its original position.
NOTE: You can lock up the mirror at
any photographing stage — before or
after advancing the film, However, do
not carry the camra in direct sunlight
with the mirror locked up. This can
result in damage to the shutter cur-
tains.

4. Determine the exposure.
First determine the shutter speed that
matches the type of flash you are
using.
Once you have set the proper shutter
speed, determine the F stop by using
the calculator dial or exposure table
attached to your flash unit. You can
determine the F stop manually by
using the following formula:
flash guide number
F stop =
flash-to-subject distance
Additional flash information can be
found in the instructions which ac-
company your flash equipment or

SX SOME QUESTIONS & ANSWERS
O: Why can't | turn the ASA film
O: My camera is loaded with film but
the rewind knob doesn’t rotate when |
advance the film advance lever. Why?
A: The film leader may not be inserted
in the film take-up spool and the film
is not advancing properly. See pages 7
8: 8.
O: The film is not advancing. Why?
A: The shutter may be cocked and
ready to fire. Release the shutter re-
lease button. If this is not the case,
your film may be fully exposed. Check
the exposure counter. If you feel ten-
sion on the film advance lever, DO
NOT FORCE IT. Rewind the film. See
pages 9 & 10.
Q: The shutter release button will not
move and |¡ can't take the picture.
Why?
A: The film advance lever may not
have been fully advanced. See page 9.
Q: The rewind crank will not turn
when | try to rewind the film. Why?
A: The rewind release lever may not be
set properly. Make sure the lever is
rotated until the red line is opposite
the “R.”” See page 10.
speed dial?
A: The film speed dial release button
must be pressed before the dial can be
turned. Once the dial had been set,
release the button and make sure the
dial has locked into place. See page 12.
Q: Why isn't the needle in the view-
finder moving?
A: First, make sure the meter switch
lever is set to the “ON” position. If the
meter is on, turn the camera towards a
bright light source. If the needle still
will not move, the battery may not be
inserted, may be inserted improperly
or may be drained. Replace the battery
or insert it properly. See page 7.
Q: The meter needle moves entirely
out of the viewfinder index. Why?
A: The meter switch lever may be at
the “OFF” position or the subject may
not be in light sufficient to make an
exposure. This indicates the warning
mechanism is working properly. Re-
select the shutter speed and F stop
combination. See pages 13 & 14.
Q: How do | take meter readings when
a bellows or extension tubes are
mounted to my camera?
A: Since lens extension devices dis-
—a23
connect the automatic diaphragm
mechanism between camera and lens,
readings must be taken with the lens
stopped-down. Take an exposure read-
ing using the procedure outlined on
page 14.
Q: The microprism in the center of the
viewfinder “shimmers’’ and gets dark.
Is that normal?
A: Yes, this is a natural phenomenon
that occurs when a lens with a maxi-
mum aperture smaller than F5 is
mounted on the camera. It also
happens with a standard lens when the
depth of field preview button is
pressed. The microprism is not faulty.
Q: The viewfinder is totally dark and |
can’t see anything. Why?
A: Make sure you have removed the
lens cap. If the cap has been removed,
the mirror lock-up lever may be in the
up position. Return the mirror to its
operational position. See page 20.
Q: When | touch the terminal socket
of the accessory hot shoe | feel cur-
rent. Why?
A: This is normal when the hot shoe is
attached. If you are not using flash or
are using a flash bracket, the shoe is
not necessary and should be removed.
See page 21.
[2 THE LENS CAP 8 LENS HOOD EX CARE AND STORAGE
„не
To attach or remove the front lens cap,
press the spring-loaded lens cap retain-
ing clips on either side of the cap. The
cap then fits easily over the accessory
thread of the lens.
M Lens hoods protect against ex-
traneous light striking the lens and
causing unwanted glare. Hoods for
standard lenses are cover types and can
be reversed to provide easy storage
even when the camera is in the case.
O When you will not use the camera
for a long period of time, store it with
the shutter uncocked and turn off the
self-timer and exposure meter. Keep it
free from dust and moisture, and re-
move it from the case.
® Do not drop the camera and avoid
hitting it,
® When storing the camera for a long
period of time, remove the battery.
Wipe the battery surface with a dry
cotton cloth before re-inserting it in
the camera.
O Never store the camera where tem-
peratures exceed 50°C (122°F). When
you use the camera in temperatures
under —20°C (—4°F), it may some-
times fail to operate properly. To avoid
this, warm the camera before use.
Protect against excess moisture by
using silica gel or other desiccant.
@® Never expose the camera to direct
sunlight. Avoid areas exposed to salt
water, salt air, radios, TV sets or
magnets.
® Avoid touching the surface of the
lens. Clean only with an air brush,
anti-static brush, or wipe it lightly with
a camel hair brush or lens tissue. In
24
EXTREME cases use a clean, soft
cotton cloth moistened with denatured
alcohol. NEVER rub the lens surface
with your finger, clothing or any other
abrasive material.
® If dust or fingerprints collect on the
mirror, focusing screen or prism, take
it to an authorized Olympus service
center. It needs professional attention.

&… MOTOR DRIVE GROUP
SYSTEM
Designed specifically to match the
OM-1, the Motor Drive Group has been
reduced in size to enhance its maneu-
verability and ease of operation. The
handgrip type motor drive provides a
built-in shutter release device making it
so compact the photographer can even
hand-hold a 300mm telephoto lens for
shooting sports or other action sub-
jects. A 250 exposure roll film back
and other units attach to the OM-1
without cords. This motor drive group
is also a convenient accessory when
used with other groups for close-up
macrophotography, photomicro-
graphy, etc.
The Motor Drive Group consists of a
number of units for sequential ex-
posures in all types of photography. A
remote control mechanism can be used
for a series of exposures in short time
period exposures taken intermittently
in conjunction with a timer, or a series
of exposures with bulk film. Framing
speeds range from one frame every 3
seconds to 4 frames per second.
The Motor Drive Group can be easily
attached to the OM-1 at any Olympus
authorized service center.

el CLOSE-UP PHOTOGRAPHY GROUP
A single lens reflex camera is probably
the most convenient method of taking
pictures at close range. You view the
subject directly through the lens for
accurate focusing and the ultimate in
composing ease. With the standard
lenses, the OM-1 lets you take pictures
as close as 45cm (17%) from the
subject. Close-up accessories help you
get even closer, enabling you to take
life-size and even larger-than-life size
pictures. The Close-up Photography
Group includes close-up lenses, ex-
tension tubes, and macro lenses that
enable you to focus even closer. The
extension tube 25 and macro lens
50mm enables you to achieve a 1:1
(life-size) close-up. The convenient
macrophoto stand facilitates your
close-up photography. The portable
copy stand holds light sources on arms
that can move to any angle and direc-
tion.
The bellows further enables you to
delve deeper into the world of close-
ups with maximum ease and remark-
able results. The copy stand is ideal for
all types of close-up applications in-
cluding copying or photographing
documents, books, biological or me-
dical specimens and small mechanical
components.

A polarizing filter can darken blue
skies without affecting the rendition of
colors or contrasts in your subject. It is
mounted on the stage of the macro-
photo stand, compatible with PM-POL.
E Lieberkuhn Reflectors PM-LM20
and 38
Two bLieberkihn reflectors are avail-
able for use with the 20mm and 38mm
macro lenses. When used with the LSD
trans-illuminator, they make it possible
to take photographs with surprisingly
good penetration and lack of shadows.
B Analyzing Filters PM-POL 20, 38
and 80
The filters are placed between the film
and the light source on the macro-
photo stand stage. Compatible with the
polarizing filter SZ-PO-P for photo-
graphy with transmitted light.
E Incident Illuminator Mirror Hous-
ings PM-EL 20, 38 and 80
These illuminators are used with
Zuiko macro lenses. The 80mm and
50mm macro lenses are used with the
iluminator PM-EL80 and the 38mm
and 20mm macro lenses are used with
the illuminators PM-EL38 and PM-
EL20 respectively. A half-mirror built
in the housing reflects light coming
from the light source into a port in the
housing bottom to evenly illuminate
the subject.

ter speeds range from 1 second to
1/500 second with T and B, and M-X
synchronizing contacts.
e.) PHOTOMICROGRAPHY GROUP
When photographing microscope im-
ages of more than 10x, it becomes
increasingly difficult to take quality
pictures. Photomicrography has spread
not only into the scientific fields (used
in medical, biological, chemical, bo-
tanical and zoological sciences for
recording observations and illustrating
scientific publications) but also is now
used in the artistic fields of graphic
design, commercial photography, dis-
plays, etc. In industries such as foods,
textiles, metal and so forth, photo-
micrography is of great value. Higher
magnification photography (over 10x
power) requires extremely precise
photomicrographic equipment and the
OM-1 offers an unusually wide range of
photomicrographic units. The Photo-
micrography Group include the photo-
microscopic adapters, the 35mm SLR
camera adapter, the exposure meter
EMM -6, the automatic exposure control!
box PM-CBA, the supporting stand
PM-PSS, eyepiece adapters, and magni-
fiers. All of these are specifically de-
signed to produce photomicrographic
results with maximum ease of opera-
tion. In addition, to these units, the
group also includes adapters for endo-
scope, stereoscopic operation micro-

E Filters
In general photography and in many
specialized fields, filters are essential to
the effective rendition of photographic
subjects. Whether in black and white or
color, filters are necessary additions to
most camera systems. In controlling
contrast and eliminating unwanted
haze in black and white photography,
the use of the correct filter often
means the difference between a good
photograph and a great one. in color,
where the balancing of the light with
the film emulsion is absolutely neces-
sary for correct color, conversion and
light batancing filters are the only
effective way of achieving the desired
results. Olympus filters are made of the
highest quality optical glass and are
tested to the same high standards used
in evaluation of Zuiko lenses. All ex-
traneous lights and aberrations have
been eliminated so as not to affect
focusing quality of any lens with which
the filter is used, and all Olympus
filters are fully coated on both sides to
| minimize flare and reflection.
