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 tha t they are indispensable

for obtaining good results.

MOUNTING AND DETACHING THE LENS

Remove the body cap and the rear lens cap.*

* 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.

Mount th e lens.

Detach the lens.

INSERTING THE BATTERIES

Remove the cover of t he battery chamber.

Insert two 1.5V alkaline-manganese batteries

LR44 (A76).

Replace the cover.

(NOTE)

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

CHECKING THE BATTERIES

Move the selector dial to "CHECK".

A beeping sound is heard and the battery check

light turns on.

After the check set ba c k the dial.

(Attention)

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

LOADING THE FILM

Load the film.

Open the camera back. (Never load or unload the camera in direct sun-

light.)

Insert the fil m leader in one of t he s lots of t he

take-up spool.

The film leader must not be excessively drawn out.

(The film leader is

twisted.)

(The film leader does

not enter completely.)

(The film leader is

excessively drawn out.)

Wind the film once.

The perforations of the film must engage with the sprocket teeth. Make sure it is well tense,

and clo se the back

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 e x-

posure time.

SETTING THE ASA FILM SPEED

Set the ASA film speed.

(The ASA film speed dial is set at ASA 100.)

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,

and w hen se t s o taking correctly exposed,

beautiful pictures could not

be simpler.

SETTING THE APERTURE

Set the desired aperture.

(Aperture guideline)

NOTE: To make full use of the aperture ring, read

page 27.

Confirm that the camera is set at the "AUTO"

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.

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-

posed photographs.

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

PHOTOGRAPHY WITH SHUTTER-SPEED PRIORITY

When photograhing fa st moving subjects, there is a marked tendency to obtain a blurred image of the subject. This can be made use of as a te chnique to g ive th e impression of movement, by intentionally allowing the image to be blurred, while making use of the shutter speed priority function.

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

shutter speed is 1 se c. or longer. In suc h a case it is recommended to tu r n the aperture ring to the lower f-numbers within the proper ex-

posure range.

Pictures taken with this technique offe r 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.

EXPOSURE COMPENSATION

When shooting against the 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 this 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 AS A 25.

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

LONG EXPOSURES

Indoors when it is dark, or when photographing

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

pictures by resorting to lon g 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 as long as th e shutter button is being pressed.

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 T32 (or T20) is turned on, the normal auto flash control begins working. Wh en 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 of 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 automatically

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.

(Continued on page 49)

•

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 the OM-10 very simply, and switched to the single or sequence mode photography. On single mode, it

can wind film immediately af ter exposure, ready

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

filming

fast

as 2.5

frames

per

second.

(Continued on page 49)

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 photo-

graphy 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

Telephoto 200mm

MAKING USE OF THE DEPTH OF FIELD

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

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

tures

< 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 a n F16 is used, th e range wi ll be a pp roximately 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.

MANUAL EXPOSURE CONTROL

When the optional Manual Adapter is attached to the OM-10, it is possible to revert to manual e x-

posure c ontrol. 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.

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 viewf inder to see the shut-

ter speed which the light indicates, and set that speed in th e Manual Adapter. Then, press the shutter release button.

* By 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 free f r om 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 whe re 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 normal temperature regularly, sometimes fa il 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, especially 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 sur-

faces clean wit h 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 th e release button at random.

Do not touch any part that moves at high speed

such as the shutter, instant return mirror, dia-

phragm, etc.

Avoid touching the surfaces of the lens. Clean

onl y wit h an 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 view 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 hea r 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 : Why doesn't the rewind knob rotat e when I

try t o advance the film?

A : The

film

leader

is not

properly

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 ak e 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 batteri 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

engaged

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

Q : I pressed the shutter release button with the

selector dial at the "OFF" position. Will the

photograph be properly exposed?

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

circuits will be activated for a proper ex posure. Recommended to develop the f ilm

and

see.

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

shutter speed is much slower than the one

indicated in the viewfinder. W hy does this happen?

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

not properly positioned behind th e shutter,

the

speed

will

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 the y may

be of the same size.

Q : A shadow appears darkening the central area

of the viewfinder. W h y does this happen?

A : This 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, what will become of the shutter?

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

the self-timer, make it a point to retu rn 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 ac-

tivator switch lightly, and the light is on

again.

(From page 33)

It is not possible to use a Motor Drive 1 w i t h the OM-10.

The viewfinder lights may turn off when using Winder 2 with your OM-10. This is due to the special energy saving circuits built into the OM-10. Simply touch the activator switch (collar sur-

rounding the shutter release), and the lights w i l l

turn on. See page 22 for further explanation.
