PREPARATIONS BEFORE TAKING PICTURES

The OM-10's circuits

are powered by two 1.5V alkaline-manganese or silver oxide batteries.

Without them, the shutter of this electronic

single lens reflex camera will not function.

This section

is devoted to explaining the preparations

which you must go through before proceeding to take pictures.

Please keep in mind th at they are indispensable

for obtaining good results.

6

* If you have purchased an OM-10 in conjunction

with a lens, the body cap and rear lens cap are

not provided.

Remove the front lens cap.

Remove the body cap and the rear lens cap.*

MOUNTING AND DETACHING THE LENS

(NOTE)

Two 1.5V silver oxide batteries SR44 (Eveready
EPX-76) or equivalents can be also used.

9

(Attention)

If no sound is heard and the light does not turn
on, the batteries have not been correctly inserted,
or their charge is exhausted. In this cas e they mus t
be replaced.

the sprocket teeth. Make sure it is well tense,

and cl ose the back

Wind the film once.

13

Take blank shots until the exposure counter
shows "1".

(Ways of taking blank shots)

This instance is not suit­able for taking blank shots

since the automatic ex-

posure control built in the

OM-10 prolongs the ex-

posure time.

THE WAY TO AUTOMATIC PHOTOGRAPHY

All the problems

of exposure are electronically taken care

by the OM-10.

It is a single lens reflex camera

which can be set for automatic control of exposure,

PHOTOGRAPHIC TECHNIQUES

The various functions of the OM-10 and

the wide variety of lenses, flash, winder, and
system accessories which can be used with it

allow you to fully master all the techniques

which automatic photography can

make possible.

We shall devote the following section

to some of these photographic

techniques.

26

CONTROLLING THE EXPOSURE

When taking pictures in a place which is either
too dark or too bright, even if you follow the
aperture guidelines given on page 17, there will
be a tendency to result in whitish photographs
(overexposure), or darkened ones (underex-

posure), or even blurred images. In these circum­stances, make full use of the aperture r ing i n order
to control exposure so as to obtain properly ex-

posed photographs.

When

a red

light

turns

on in the red

zone

at

the top of the shutter speed scale in the view-

finder it indicates overexposure.
In such a case, turn the aperture ring to the
higher f-numbers (toward F16) until the light

appears within the proper exposure range, and

then proceed to tak e the picture.
When the light appears below "30" (1/30 of
a second), blur may easily occur.

In this case, use a tripod or turn the aperture
ring to the lower f-numbers (toward F1.8)
until the light goes higher within a range in

27

When photograhing fast moving subjects, there is
a marked tendency to obtain a blurred image of
the subject. This can be made use of as a techni­que to gi ve t he impression of movement, by inten­tionally allowing the image to be blurred, while
making use of the shutter speed priority function.

Pictures taken with this technique off er an inter­esting challenge. Turn the aperture ring until the
light in the viewfinder appears by the shutter
speed value suitable for the photographic situa­tion,

and

then

press

the

shutter

release

button.

which blur is not likely to occur.
When the light appears at "1" (1 sec.), the

shutter speed is 1 s ec . or longer. In su ch a case

it is recommended t o tu r n t he aperture ring to

the lower f-numbers within the proper ex-

posure range.

PHOTOGRAPHY WITH SHUTTER-SPEED PRIORITY

28

When shooting against t he light, or if the subject

is standing before a window, the face tends to ap-

pear dark on the image. In this case, use the ex-

posure compensation dial to obtain a correctly

exposed photograph.

Lift the compensation dial and change the
film speed set on the dial (within ±2).
By thi s means, it is possible to obtain high or

low key effects. (+) is for high key (overex-

posure) and (—) is for low key (underex-

posure). However it is not possible to obtain

(-) compensation for ASA 1600 or the (+)

(For example, ASA 100 compensated +2 full stops.)

compensation for ASA 25.

When you finish taking the picture, r eturn the
compensation dial to its original position.

EXPOSURE COMPENSATION

29

LONG EXPOSURES

Indoors when it is dark, or when photographing

at night, use the "BULB" setting and take the

pictures by resorting to long exposures. Of course,

blur can easily occur in long exposures so it is re-

commended to use a tripod and a cable release.

Set the mode selector lever to B, and press the

shutter release button.

The shutter will remain open a s long as t he
shutter button is being pressed.

Do not

forget

to

reset

at the

"AUTO"

position

after you finish taking pictures.

(Continued on page 49)

FLASH PHOTOGRAPHY

Electronic

Flash T32

Electronic

Flash T20

The T32 and T20 electronic flash units specifi­cally designed for OM cameras provide artificial

illumination when you take pictures at night or

indoors.

< Characteristics of flash photography using the
T32•T20 >

Mount the Electronic Flash T32 (or T20) on
the accessory shoe of the camera. When the
ON-OFF switch of the T 32 (or T2 0) is turned
on, the normal auto flash control begins work­ing. W hen turned off , it reverts to the camera's
AE photography. It takes but a flick of a
finger to change it from one to the other.
When the ON-OFF switch of the T32 (or

T20) is turned on, the flash will be automati-

cally synchronized at the shutter speed o f the

camera.

It is possible to verify when the flash is ready
because a full charge signal lights in the view­finder.

In addition to the charge signal automaticall y

lighting at you can refer to the shutter speed

indicated by another red light in the view-

finder as required by the available light.

It is possible to check a correct flash exposure

in the viewfinder if the signal light blinks.

USING THE WINDER 2

Fast moving subjects, such as in sports, car racing,

and the like, make you wish to take pictures at a

faster pace.

The time spent winding the film may mean that a
great chance is lost. In these cases, an accurate,
reliable power winder for automatic film winding
can well be the perfect answer, such as the

Olympus Winder 2 which can be attached on th e
OM-10 very simply, and switched to the single or
sequence mode photography. On single mode, it

can wind fi lm immediately a fte r exposure, ready

for next chance to release the shutter at a ny mo­ment, and on sequence mode, it can make sequen­tial

filming

as

fast

as 2.5

frames

per

second.

FROM GENERAL PHOTOGRAPHY TO THE USE OF INTERCHANGEABLE LENSES

The main characteristic of the single lens reflex
camera is the possibility of using a plurality of
different lenses on the same body. From photo­graphy with a standard lens to the feeling obtain­ed with a telephoto lens by blurring the back­ground or, on the other hand, by stressing the
perspective, giving a special effect to the back­ground by means of a wide angle lens, the world
of images which unfolds before you with the
OM-10 becomes richer and wider. Olympus Zui­ko interchangeable lenses included in the OM
System are highly reputed for their sharpness and

resolving power.

Wide angle 28mm

35

Telephoto 200mm

36

MAKING USE OF THE DEPTH OF FIELD

When y ou have a subject in focus, there is a range
in the fore and the background which is clearly
defined in the picture. This range is call ed depth
of field. The larger the F number becomes, the
wider this clearly defined range becomes, and
the background becomes sharper. On the con­trary, the smaller the F number becomes, this
range

becomes

less

wide,

while

the

background

loses contrast and out of focus. By using these
properties of the depth of field with creativity
and imagination, you will be able to take pic-

tures

which

will

have

your

own

personal

im-

print.

37

< How to check the depth of field >

The photograph is focused at a distance of
about 4m (13 ft).

In this case, if the aperture is set at F 4, the
range which appears clearly defined will be
approximately from 3m (10 ft) to about

4.5m (15ft).

If an F16 is used, the range w ill be ap proxi­mately between about 2m (6.6 ft) and 10m

(33

ft).

When you want to check inside the viewfinder
the correct focusing range, it simply requires
pressing this preview button.

38

MANUAL EXPOSURE CONTROL

When the optional Manual Adapter is attached to
the OM-10, it is possible to revert to manual ex­posure control. When photographing fast moving
subjects, when there is a possibility of camera
shake, or when you want to capture the subject

in its natural tones no matter what the illumina­tion behind may be, this accessory proves to be
very useful. In order to control exposure in such
a way as to obtain special effects to match the

photographic situation or your own intentions,

you must rely on your own expertise and practice.

In photography with manual control of exposure,
the mode selector lever must be set at the "MAN-

UAL ADAPTER" position.

To use the electronic flash T32 or T20 with the

Manual Adapter attached on, you must set the

mode selector lever to AUTO and the flash unit

automatically synchronizes at the shutter speed
of the camera.

(CAUTION) If an electronic flash other than the

T32 or T20 is used with the Manual Adapter,

sometimes the shutter is not released at the speed

you set on the Adapter due to the noise of the

flash.

39

Shutter-speed priority at 1/1000 sec.

< When shutter-speed priority is advisable >

Set the necessary shutter speed in the Manual

Adapter.

Turn the aperture ring while looking through
the viewfinder until the light on the shutter
speed scale turns on at the shutter speed which

was set in the Manual Adapter. Then, press
the shutter release button.

Aperture priority, high keyed

< How to apply aperture priority to your photo-

graphic needs >

Set the aperture as preferred.

Look through the viewfi nder to see the shut-

ter speed which the light indicates, and set
that speed in the Manual Adapter. Then, press
the shutter release button.
* B y intentionally ignoring the indicated shut-

ter speed, and setting a different one in the

Manual Adapter it is possible to obtain high

key or low key results as desired.

CARE AND STORAGE OF THE CAMERA

General

Dust and moisture are primary harmful agents
affecting your camera. When you do not use
the camera, remove it from the case and store

in a dry, ventilated place, making sure that the

shutter is set f re e fro m tension and the selector

lever at the OFF position.
When storing the camera for a long period of

time, remove the batteries. Wipe all battery sur-

faces with a dry cotton cloth before re-insert-

ing them into the camera.

Avoid dropping or hitting the camera.

Never store the camera where temperatures ex­ceed 50°C (122°F). When you use the camera

in temperatures under — 20°C (—4°F), it may

sometimes fail to operate properly. To avoid

this, warm the camera before use. Protect

against excess moisture by using silica gel or
other desiccant.

Generally speaking, a battery voltage may be

reduced when an ambient temperature lowers.
As the batteries that activate the camera at nor-

mal temperature regularly, sometimes f ail to in

low temperature, it is recommended to use fresh

batteries in a cold district.
Take care not to permit water to enter the cam-

era when taking pictures in the rain or snow, es-

pecially near sea-water spray, as water drops
may easily have a chance to enter the camera

through small orifices.

After use near the ocean, wipe the camera sur­faces clean with a soft cloth; never leave salt on
the camera. (Salt may be airborne near the
ocean and collect on the camera even though it

has not been in direct contact with water.)
Avoid areas exposed to salt water, radios, TV

sets, or magnets.

Have all repairs performed by an authorized
OLYMPUS Service Center. You may send it
directly or through the store where you bought

your camera.

Parts

Do not press the release button at random.

Do not touch any part t hat moves at high speed

such as the shutter, instant return mirror, dia-

phragm, etc.

Avoid touching the surfaces of the lens. Clean

43

onl y w ith a n air brush, antistatic brush, or wipe

it lightly with a camel hair brush or lens tissue.

In EXTREME cares, use a clean, soft cotton

cloth moistened with denatured alcohol. NE V-

ER rub the lens surfaces with your finger, cloth­ing or other abrasive material.

If dust or fingerprints collect on the mirror,

focusing screen, or prism, take the camera to

an authorized OLYMPUS Service Center. It

needs professional attention.
Avoid excessive force when mounting on a

tripod.

QUESTIONS AND ANSWERS

Q : I can neither release the shutter even by press-

ing the shutter release button, nor advance

the film. Why?

A : Because no batteries are loaded. Load fresh

batteries.

Q : Why is the field of vi ew dark and the image

obscure?

A : Because the batteries are exhausted. Replace

them.

Q : Why can't I move the film advance lever?

A : The self-timer may be set, or the shutter re-

lease may be cocked and ready but it has
not been pressed yet. If you press the shut-

ter

release

button,

film

will

advance

to the

next frame. Has the film reached its end?

Check the exposure counter and, if it shows
that the film has ended, rewind the film. Are
the alkaline-manganese or silver oxide bat­teries charged? Check the batteries, and if
yo u hear the beeping sound and see the red

light flashing, but cannot move the lever,
take your camera to an authorized OLYM-

PUS Service Center.

Q : W hy doesn't the rewind kn ob rotate when I

try to advance the film?

A : The

film

leader

is not

properly

engaged

on

the film take-up spool. Insert the film leader
again.

Q : Why won't the rewind crank turn?

A : Set the rewind release lever once more in

the direction of the arrow, and the problem

will be solved.

Q : Is infrared photography also possible with

the OM-10?

A : Yes, it is if you use the manual adapter and

set the mode selector lever to the MANUAL

ADAPTER position. Then, t a ke the follow-

ing steps:

Focus without a filter. Move
the focusing ring to coincide with the infra­red mark. Mount a filter for infrared photo­graphy, and proceed to take the picture.

Q : When should I check the ba tteri es?

A : When new batteries are inserted.

After the camera has been stored for a

long time.

When you think batteries may be ex­hausted.

The alkaline-manganese batteries should

45

last for about a half year, and the silver
oxide batteries fo r about one year.
When the temperature is extremely low.

Q : I pressed the shutter release button with the

selector dial at the "OFF" position. Wi l l the

photograph be properly exposed?

A : Even at the "OFF" position, the camera's

circuits will be activated for a proper e x­posure. Recommended to develop the fi lm

and

see.

Q : When set at the "AUTO" position, the actual

shutter speed is much slower than the one

indicated in the viewfinder. Why does this
happen?

A : If film is not loaded or the film surface is

not properly positioned behind t he shutter,
the

speed

will

be

slower

than

that

indicated

in the viewfinder.

Q : What batteries should I use?

A : Use two 1.5V alkaline-manganese batteries

LR44 (A76) or two silver oxide batteries

SR44 (Eveready EPX-76 or equivalents).

Batteries of a different type (1.3V mercury
batteries) cannot be used, though t he y may

be of the same size.

Q : A shadow appears darkening the central area

of the viewfinder. Why does this happen?

A : Th is is quite usual when a lens with a maxi-

mum aperture smaller than F5 is mounted
on the camera, and the preview button is
pressed with the diaphragm closed down
beyond F5. There is nothing wrong with

the microprism.

Q : If I return the selector lever to the ON posi-

tion, while the self-timer in operation, wha t
will become of the shutter?

A : The shutter will be released. After the use of

the self-timer, make it a point to ret urn the

selector lever to original position.

Q : While I was operating the Winder 2, the light

in the viewfinder went out... why?

A : The

light

goes

out in 90

sec.

even

the

selector

lever is ON, in order to save the batteries from
unnecessary consumption. Touch the ac­tivator switch lightly, and the light is on
again.
