MOUNTING THE LENS INSERTING THE BATTERIES

Mount the Lens.Align the red dots on the lens flange and the bodymount ring. Turn the lens clockwise until the lensrelease button springs up and you will hear posi-tive "click".Lens RemovalTo detach the lens, pressdown on the lens releasebutton and turn the lenscounter-clockwise. Alwaysattach the front and rearlens caps when the lens isremoved from the body toprevent any possibility ofdamage.

Insert two 1.5V silver oxide batteries SR44(Eveready EPX-76 or equivalents) into the bat-tery chamber.CAUTION: Batteries should be always replacedas a pair. If battery polarity is incorrect, the cam-era does not function.

BATTERY CHECK AND MIRROR LOCK-UP

a point to switch off the selector lever when thecamera is not used.

By pressing the selector lever to the "CHECK•RESET" position, you can check the batteriesand/or unlock the mirror.Check the Batteries.Move the selector lever to the "CHECK•RESET"position. The battery check lamp indicates bat-tery condition as follows:

The red lamp lights brightly — Battery volt-age is sufficient.

The red lamp flashes on and off — Batteriesare very weak. Fresh batteries are recommended.

The lamp does not light — Batteries are drain-ed. Replace them.NOTE: Silver oxide batteries will last approxi-mately one year. To avoid battery drain, make it

Mirror Lock-UpIf the mirror is up, the field of view turns darkthrough the viewfinder, and the film cannot beadvanced. This lock-up of the mirror occurs when

no batteries are loaded or batteries are deplet-ed, or the film is advanced during exposure.The mirror lock-up does not indicate any break-down of the camera, but a built-in safety deviceto prevent any trouble. Press the selector lever tothe "CHECK•RESET" position, and unlock themirror. In case , shooting can be resumed im-mediately. In case , replace batteries.CAUTION: You cannot unlock the mirror afterbattery replacement, if you omit pressing theselector lever to the "CHECK•RESET" position.NOTE: When the mirror locks up, a battery drainprevention device is activated to conserve power.

LOADING THE FILM

Pull the rewind knob upand open the camera back.Insert a film cartridge intothe film chamber and pushthe rewind knob back.Insert the film leader intoone of the slots in the filmtake-up spool.

Turn the advance lever so that the film perfora-tions engage the sprocket teeth.Close the camera back until it clicks.Make sure the selector lever is in the OFF posi-tion.

NOTE: Fold out the rewind crank and rotate itclockwise slightly to remove any slack in the film.Then if the rewind crank rotates as you turn theadvance lever, the film is properly advancing.

9

OPERATING THE FILM ADVANCELEVER EXPOSURE COUNTER

Turn the advance lever to the right as far as it willgo. The film can be advanced by one frame, in asingle stroke or in multiple short strokes.NOTE: If the advance lever stops moving becauseyou've shot the last remaining film frame whileyou are advancing the film, discontinue the filmadvance and rewind the film. (Read pages 37~41for motor drive shooting.)

Exposure CounterThe exposure counter is indexed from "S" (Start)to 1, 2 ... up to 36 in even numbers and "E"(End). Whenever the camera back is opened, theexposure counter automatically returns to "S".

10

SETTING THE ASA FILM SPEED DIAL

Lift up the outer collar of the exposure com-pensation dial and rotate until the ASA speedfor the film appears in the window.The ASA film speed scale on the dial is mark-ed from 12 to 1600. If you are not able torotate the outer collar to the desired ASA inone turn of the dial (only 3 stops can be rotatedin one turn of the dial), release the collar andturn the exposure compensation dial severalclick stops in the opposite direction from theASA you are trying to set. Then, lift the outercollar again and continue turning to the desir-ed ASA setting. NEVER FORCE THE DIALWHEN SETTING ASA.

Once the setting has been made, turn the dialuntil the white line is aligned with the blackindex line on the pentaprism housing.CAUTION: Make sure you align the white linewith the black index line on the pentaprismafter setting ASA.

THE MEMOHOLDER

A memo holder pro-vided on the cam-era back accepts amemo slip or theend flap from most35mm film packagesas a reminder ofASA, exposure number, etc.

11

APERTURE RING AND MANUAL SHUTTER SPEED RING

Aperture RingThe opening (aperture) in the lens diaphragm ismarked in F stops on the aperture ring. The higherthe F number, the smaller the lens opening (lesslight) and provides greater depth of field thanlower F numbers (see page 25).When setting the aperture ring, you may use eitherthe click-stop positions or any in-between settingsto obtain precise exposure control.NOTE: All lenses in the OM System (except cer-tain specialized lenses) provide fully automaticdiaphragm control allowing you to focus andcompose your picture with the lens fully open.The diaphragm will automatically close to thepre-selected F stop at the moment of exposure.And immediately re-open after exposure.

Manual Shutter Speed RingShutter speeds engraved on the manual shutterspeed ring are used only for non-automatic cam-era operation. B indicates "bulb" at which set-ting the shutter will remain open as long as theshutter release button is held down. The otherengravings indicate fractions of a second; for ex-ample "T" for 1 second, "2" for 1/2 second .....up to "1000" for 1 /1000 second. To set at "B",rotate the ring while pressing the B LOCK but-ton at the lower left of the body mount.Be careful that shutter speeds are set only atclick stop positions. Make sure that the selectorlever is set at a click stop position.

12

SETTING THE SELECTOR LEVER

The selector lever on top of your camera has fourpositions as follows (with click stops atAUTO-OFF-MANUAL):1) AUTO — Automatic exposure control; you

preset the F stop and the camera automatical-ly sets shutter speed for proper exposure.

2) OFF — Camera turned completely off to avoidbattery drain. Always store your camera withthe selector lever in this position.

3) MANUAL — Zero-method exposure operation;set shutter speed and F stop for proper ex-posure (see page 17).

4) CHECK•RESET — Battery test position simul-taneously with release of mirror lock-up.

The three-position viewfinder control centerallows you to see the operating mode of yourcamera without checking the position of theselector lever.NOTE: If you release the shutter with the selectorlever at OFF in normal lighting condition, thebuilt-in automatic exposure control is activatedto take a properly-exposed picture, so as not tomiss optimum exposure opportunity, at any mo-ment. The difference between the automatic ex-posures in the OFF position and the AUTO posi-tion, however, is that the OFF mode exposurestops in 1/30 sec. maximum to save battery ex-haustion, and the AUTO viewfinder scale doesnot appear.

FOCUSING

Look through the viewfinder and turn the focusingring in either direction until your subject appearssharpest. The split image will be vertically alignedin the central spot of the Focusing Screen or ashimmering effect of the microprism ring aroundthe central spot will disappear when critical focus-ing has been achieved.NOTE: You can determine the distance betweenthe subject and the film plane by reading the dis-tance scale on the focusing ring after setting criti-cal focusing. The actual distance is indicated op-posite the red central index mark on the lensmount ring; the white scale indicates this distancein meters and the orange scale in feet.(For Focusing Screen replacement read pages 28,59 and 60).

AUTOMATIC EXPOSURE CONTROL

The Aperture-Preferred SystemThe aperture-preferred systemis the most convenient andeasy-to-use method of auto-matic operation, particularlyoutdoors when using 50mm orwide-angle lenses. To use this system:

Set the selector lever to the "AUTO" positionmaking sure that the lever "clicks" into place.

Set the F stop you wish to use on the lensaperture ring.

The camera will automatically determine theshutter speed required for proper exposure andindicate that speed in the viewfinder. Then RE-

LEASE THE SHUTTER.NOTE: At shutter speeds slower than 1/60 second,the possibility of camera movement during ex-posure is increased. If the needle in the viewfinderindicates a shutter speed in this area, turn theaperture ring to the left (so as to open the aper-ture).For use of interchangeable lenses of various anglesof view, refer to the data below to determine thehand-held shutter speed and avoid blurry pictures:

Wide-angle and super wide-angle lenses — 1/30second or faster. 50mm lenses — 1/60 secondor faster. Telephoto and Zoom lenses to100mm — 1/125 second or faster. Telephotoand Zoom lenses to 200mm — 1/250 second or

Red Zone

Blue Zone

15

faster. Super telephoto lenses of 300mm andup — 1/500 second or faster.

If the viewfinder needle enters the red zoneWarning against over-exposure. A shutter speedfaster than 1 /1000 second is required for pro-per exposure, but the shutter will be releasedat 1/1000 second. Since this is beyond therange of your OM-2 and an overexposed photo-graph would result, turn the lens aperture ringto a higher F stop until the meter needle movesout of the red zone.If the viewfinder needle enters the blue"AUTO" zone Indication for long time ex-posure. A shutter speed longer than 1 secondis required for proper exposure.Your OM-2 provides for automatic exposuresfrom 1 second to 120 seconds (with ASA 100at normal temperature and humidity). If youwish to close the shutter during a long timeexposure under AUTO operation, turn theselector lever to the OFF position, and theshutter closes.CAUTION: Do not advance the film whilethe mirror is up during an automatic exposure,or the mirror will lock up.

The Shutter Speed-Preferred SystemShould you wish to select a shutter speed to meeta specific photographic situation (e.g., stoppingfast action, eliminating camera movement or con-trolling depth-of-field), you may use a shutterspeed-preferred method of automatic exposurecontrol. To use this system:

Set the selector lever to the "AUTO" position.Look through the viewfinder and turn theaperture ring until the viewfinder needlepointsat the desired shutter speed.

16

MANUAL EXPOSURE CONTROL

Set the selector lever to"MANUAL", and the ex-posure index marks andthe meter needle are visi-ble in the viewfinder.

Shutter Speed-Preferred Manual Exposure ControlShould you wish to preselect a shutter speedturn the shutter speed ring until the desiredspeed is opposite the red reference dot on thelens barrel (see page 12).Look through the viewfinder and turn theaperture ring until the needle lines up in thecenter of the index. For fine exposure adjust-ment you can use any click-stop or inter-mediate F stop position.

Aperture-Preferred Manual Exposure ControlTurn the aperture ring until the desired F stopis opposite the white index mark.Look through the viewfinder and rotate theshutter speed ring until the needle lines up asclose as possible to the center of the index.Make sure that the shutter speed ring is clickedinto position and not between two settings.Make the final exposure adjustment by turningthe aperture ring until the needle aligns exactlyin the center of the index.

CAUTION: The shutter speed thus obtainedshould meet the other photographic conditionsproperly, especially at "B" where the shutterspeed ring is not coupled with the exposure meter.

17

Exposure Meter Needle

Exposure Meter Index

If the Exposure Needle Does Not Center on theIndexIf an exposure or a shutter speed is improperlyselected, the exposure needle will not center onthe index. Reset the shutter speed or F stop untilthe needle is centered.You may use an ND (neutral density) filter if thesubject is too bright, or an electronic flash or flashbulb if the subject is too dark.

Light Measuring Range of the Exposure MeterThe measuring range is EV 1.5-EV17 (ASA 100,with F1.2 55mm lens). The list above summarizesthe lowest measurable limits in dealing with ex-treme low light conditions.CAUTION: If the aperture ring or shutter speedring is turned below the limits in the list, with ex-tremely low lighting or the selector lever OFF,the needle sometimes moves, but the meter is notfunctioning.

18

HOLDING THE CAMERA

Proper camera handling is important in assuringthe sharpest possible pictures.Holding the Camera HorizontallyKeep both elbows close to the body, to steadythe camera.Putting the Camera into OperationThe aperture ring, focusing ring and shutter speedring 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 rightthumb and squeeze the release button smoothlyusing the cushion, not the tip, of your indexfinger.

Holding the Camera VerticallyFor vertical shooting, keep one elbow close toyour body and press the camera tightly againstyour forehead.NOTE: Steady yourself against any nearby sup-port (such as a tree, fence, or wall) whenever pos-sible.NOTE: For telephotography, or slow shutterspeed photography, it is recommended that youuse a tripod and hold the camera steady withyour hands.

19

UNLOADING THE CAMERA

When the entire roll of film has been exposed re-wind the film.

Turn the rewind release lever counter-clock-wise by about 90°.Fold out the rewind crank and wind it in thedirection of the arrow. While rewinding, youwill feel tension on the crank. When the ten-sion stops and the crank turns freely, the filmhas been completely rewound back into thecartridge.Open the camera back by pulling up on therewind knob and remove the film cartridge.Keep camera and film out of direct sunlightwhile unloading.

Should you wish to make more than one exposureon the same frame:

Take up any slack in the film by slowly turn-ing the rewind crank in a clockwise directionuntil it stops, then take the first exposure.Turn the rewind release lever counter-clock-wise by about 90°.Hold both the rewind knob and rewind re-lease lever to prevent them from turning andadvance the film advance lever. The shutterwill then be cocked for the next exposurewithout advancing the film.Press the shutter release button with a slow,steady squeeze.The exposure counter will advance with eachexposure.After completing the multiple exposures, putthe lens cap on the lens, advance the film, andshoot a blank frame to avoid overlapping.

NOTE: You can make as many multiple exposureas you like by repeating the above procedure. Witheach exposure on the same frame, the possibilityof slippage is increased.

MAKING MULTIPLE EXPOSURES

20

SETTING THE SELF-TIMER

Rotate the self-timer lever counter-clockwiseso that the shutter can be released after anelapse of delay time between 4 sec. to 12 sec.according to the lever setting as shown above.You may set the self-timer lever either beforeor after advancing the film.Turn the start lever clockwise to the verticalposition to activate the self-timer lever. Theshutter will then be released after the presettime.

Stopping the Self-timerTo stop the self-timer during its operation, turnthe start lever counter-clockwise. If you turn thestart lever clockwise again, the self-timer can re-sume its action.NOTE: After setting the lever, you can releasethe shutter by pressing the shutter release button.NOTE: If you do not reset the self-timer, thetimer lever will begin moving immediately afteradvancing the film and the shutter will be releas-ed earlier than expected. If the film has not beenadvanced fully, the timer lever will stop half-way.To re-activate the timer, move the start levercounter-clockwise to stop the timer lever, returnthe timer lever to the starting position, and ad-vance the film. Then, turn the start lever again.

21

EXPOSURE COMPENSATION

Before compen-sation

When the most im-portant area of the picture is much darker thanthe general picture area (blue sky, snowfield,etc.), the meter will have a tendency to read thebrightest part of the picture leaving the main sub-ject under-exposed. Alternatively, when taking apicture of a bright subject against a dark back-ground the meter tends to read the darkest part

Before compen-sation

leaving the main subject over-exposed. In thesesituations, proper exposure compensation helpsyou take fine pictures.NOTE: With backlighting or sidelighting it's al-ways a good idea to use a lens hood to eliminateunwanted glare.

After compensation After compensation

22

EXPOSURE COMPENSATION FOR AUTOMATIC MEASUREMENT

If you wish to change the exposure setting auto-matically selected by the camera, use the exposurecompensation dial and a compensation markerappears in the viewfinder.When the main subject is much darker than thegeneral background or when strong light strikesthe subject from behind or from the side, turnthe dial to the (+) side.Turn the camera to the subject so that the subjectfills most of the viewfinder, or move the cameratoward the subject. After reading the shutterspeed, return to the original position and rotatethe compensation dial until the meter needlepoints at the read-out speed in the finder.NOTE: In such a case it is recommended to turnthe compensation dial to the + 1 side.

When taking a picture of a bright subject againsta dark background (spotlightng, deep shadows,etc.), turn the compensation dial to the (—) side.Move forward until the subject fills as much ofthe viewfinder as possible, (with a zoom lens, youmay be able to do this by zooming in on the sub-ject without chaning your positions). Afternoting the shutter speed indicated by the meterneedle, return to your original position, recomposethe picture, and turn the compensation dial untilthe shutter speed needle indicates the speed ob-tained from your close-up meter reading.

23

EXPOSURE COMPENSATION FOR MANUAL MEASUREMENT

1 Stop Over 1/2 Stop Over Correct Exposure 1/2 Stop Under 1 Stop Under

Manual exposure can be compensated by adjust-ing the F stop or shutter speed. The exposureneedle indicates over-exposure at the (+) side, orunder-exposure at the (—) side.Dark subject in bright backlightingWhen the most important area of the picture ismuch darker than the general picture area (stronglight hitting the main subject from behind or fromthe side) the meter will have a tendency to readthe brightest part of the picture leaving the mainsubject under-exposed. To compensate for this,move forward until the subject fills most of theviewfinder picture area and set the F stop/shutterspeed combination which centers the meter needlebetween the index marks. Return to your original

position and take the picture without changingthis F stop/shutter speed combination even thoughthe needle is not centered.NOTE: Over-exposure by + 1 stop renders a goodresult in such a case.

Bright subject in dark backgroundAs previously mentioned, fill the viewfinder pic-ture area with the subject as much as possible,and set correct light measurement. Return to youroriginal position and expose for fine pictures.

CAUTION: After taking a picture using the com-pensation dial, be sure to return the dial to thenormal setting

24

DEPTH OF FIELD

F16, 1/15 sec.

F2, 1/1000 sec.

Depth of field is the area of acceptable sharpnessin front of and behind the subject in focus. Asyou get closer to your subject or as you open yourlens (e.g. from F16 to F2.8) the depth of fieldbecomes shallower. By stopping your lens down

(e.g. from F2.8 to F16) or getting farther awayfrom your subject this depth of field can be in-creased.The table below shows that when the camera-to-subject distance is 3m, the depth of field atF16 ranges from 1.93m to 6.93m.As you press the preview button, looking throughthe viewfinder, you can ascertain the actual depthof field.

Depth of Field Table (F1.8 & F1.450mm Lenses)Circle of least confusion 1 /30mm

25

DEPTH OF FIELD SCALE PREVIEW BUTTON

The double series of numbers engraved on thedepth of field scale represents F stops: F4, F8,and F16. Once you have focused on your subject,all objects within the distance range indicatedon the lens distance scale between the marks forthe F stop you have selected will have acceptablesharpness. For example, in the above picture, thecamera-to-subject distance is 3m (10ft.) and thelens is set at F16. If you read the distance scaleat the points opposite the engraved "16" on bothsides of the reference dot, you will find that thedepth of field is from 1.9m (6ft.) to 7m (23ft.).

When you wish to see which objects fall withinthe acceptable zone of sharpness (depth of field),press the preview button on your lens. The dia-phragm of the lens will stop down to the presetF stop enabling you to see the depth of field inthe viewfinder.CAUTION: If you jerk the preview button whiledepressing the shutter release button halfwaydown the shutter might be released.

26

INFRARED PHOTOGRAPHY CAMERA BACK REPLACEMENT

The OLYMPUS OM System Lenses are providedwith an infrared index mark engraved in red onthe depth of field scale.When shooting with infrared film, focus normallyon your subject without the red filter on and readthe subject distance on the distance scales. Then,turn the focusing ring to the right until the dis-tance reading is opposite the infrared index mark.Your lens will then be in focus for average in-frared photography. Shoot with the red filter on.In the above picture, the red index is set at infinity.CAUTION: Due to special light gathering require-ments of infrared films, it is recommended thatyou follow the film manufacturer's recommenda-tions regarding exposure.

The camera back of the OM-2 is fully interchanbe-able with the Recordata Back 2, 3 and 250 FilmBack 1. To remove the camera back, push downon the release pin as shown. Do not remove theback unless necessary.The Recordata Back 2, 3 registers data such asdate, number, alphabetical code, etc. directly onthe picture.The 250 Film Back 1 is designed for winder ormotor drive shooting; it accepts a bulk loadedmagazine of 250 frames.

27

INTERCHANGEABLE FOCUSING SCREENS

The OM System interchangeable focusing screensprovide you with the ultimate in focusing versa-tility. Optional screens are available to suit virtual-ly every picture-taking situation. The focusingscreens come with a special tool. To remove thefocusing screen:a) Detach the camera lens from the camera body.b) Use the special tool provided to push up on

the release catch underneath the top ledge ofthe mirror box (see the photo above). Thisallows the screen and screen frame to dropdown.

c) Remove the screen from inside the camera bygripping the tip of the screen with the tool asshown.

CAUTION: Although the above procedure can bedone with fingers, it is recommended that youuse the special tool supplied. Changing focusingscreens is a procedure to be exercised with greatcare. Trying to change a screen with your fingerscan result in fingerprints and costly damage tothe surface of the screen, the prism, or the mirror.Should this occur, cleaning or repair MUST behandled by an authorized service center. Suchdamage is not covered by the product warranty.

d) To install the screen, fit it into the frame andpush the frame upward gently until it clicksinto place. Gently shake the camera body tomake sure the screen is held securely in place.

The T32 and T20 are the world's first fully auto-matic electronic flash units. All their functions arecontrolled directly by the OM-2 to perform ex-tremely easy, yet highly accurate flash exposures.(See pp. 61~69 for further information on flashunits.)

29

Attach the Acces-sory Shoe 4 to theOM-2 and mount theT32 (or T20).Set the camera's se-lector lever to the"AUTO" positionand switch on theT32 (or T20).

NOTE: Mounting the T32 (or T20) on the acces-sory shoe automatically completes the "X" syn-chro circuit. It is not necessary to set the X andFP flash selector to "X".

A red lamp lights in the viewfinder when theT32 (or T20) capacitor is charged ready forshooting.Set the aperture ring to the f/stop you require,focus on the subject and release the shutter.NOTE: All f/stops on the camera lens can beused.

The dial settings required of conventional"auto" flash units — ASA film speed setting,aperture setting, flash mode switching, exposurecompensation — are not needed with the T32(T20).

Unlike conventional auto flash units which re-gulate flash emission by an independent light sen-sor, the T32 (T20) utilizes the OM-2's own built-in SBC light sensors, so that flash acceptance anglealways coincides with the picture angle of thecamera lens.

The OM-2 shutter automatically closes at theinstant the flash exposure has been completed.

eliminating camera shake. Correct exposure canbe confirmed without taking your eye off theviewfinder.

By the incorporation of an incorrect flash pre-vention system, the electronic flash will not fireif the shutter speed is faster than the synchroniz-ing range.

Special techniques such as diffused lightingare made easy, obviating complicated compensa-tions and guesswork.

Usable flash-to-subject distance range is greatlyexpanded - from 18cm (F22) to 26m (F1.2)with a guide number of 32 (ASA 100, meters).(From 0.6 ft. to 86 ft. with a guide number of104 at ASA 100.).

BOUNCE FLASH

The T32 flash surface can be tilted upward throughan angle of 90°, providing easy bounce TTL Autoflash.

Point the flash surface at the ceiling so thatthe subject is illuminated by soft reflectedlight.

33

CLOSE-UP FLASH

Close-up in TTL Auto flash can be achieved sim-ply by tilting the flash surface downward (up to15°).

FLASH PHOTOGRAPHY WITH AN ELECTRONIC FLASH UNIT OTHER THAN THE T32-T20

Attach the Accessory Shoe 4 to the OM-2.Mount the electronic flash on the accessoryshoe.If your electronic flash unit does not have adirect contact "hot shoe", connect its syn-chronizing cable to the camera flash socket.Set the synchro terminal to "X" by aligningthe red dot on the FP and X selector withthe "X" indication alongside the flash socket.

Set the ASA film speed on the flash unit.Set the shutter speed ring to 1/60 sec. or slow-er.Set the flash unit to the automatic or manualsetting.Set the desired F stop on the flash unit (in thecase of auto mode), and then set the aperturering to this F stop. In the case of manual mode,F stop can be determined by using the follow-ing formula:NOTE: Mounting the electronic flash unit on the

accessory shoe automatically completes the "X"synchro circuit. However, there are some flashunits which do not fire unless the selector is setto "X".

[With Quick Auto 310]The Quick Auto 310/OM-2N (not OM-2)combination cannot perform the TTL("OTF") Auto flash. Use it in the NormalAuto or Manual flash mode.Set the camera's selector lever to "MANUAL".

35

FLASHBULB PHOTOGRAPHY

Plug the synchronizing cable leading from theflash unit into the camera flash socket, andthen attach the flash unit to the camera.Select the proper synchro setting from thetable below according to the type of bulb be-ing used, and align the red dot on the X andFP flash selector with the "X" or "FP" in-dication alongside the flash socket.

CAUTION: With the clip-on type "FP" class flashunit, the synchronizing cable must be used toconnect the unit and the camera.

Select the proper shutter speed from the tablebelow, and set the shutter speed ring accord-ingly.

Determine the correct F stop for flash exposureby using the calculator dial, exposure chart orguide number formula. Set the aperture ringto this F stop.

The table indicates proper synchronization speeds for most flash equipment.

CARE AND STORAGE

GeneralDust and moisture are harmful agents affectingyour camera. Remove the camera from the caseand store it in a dry, well-ventilated place mak-ing sure the shutter and self-timer are free fromtension. Do not store the camera near moth ballsor similar volatile chemical materials to avoidthe possibility of damage to metal surfaces.When storing the camera for a long period oftime, remove the battery. Wipe battery surfaceswith a dry cotton cloth before re-inserting intothe camera.Avoid dropping or hitting the camera.Never store the camera where temperatures ex-

ceed 50°C (122°F). When you use the camerain temperatures under — 20°C (—4°F), it maysometimes fail to operate properly. To avoidthis, warm the camera before use. Protect againstexcess moisture by using packs of silica gel orother desiccant in the storage area.After use near the ocean, wipe the camera sur-faces clean with a soft cloth; never leave salton the camera. (Salt may be airborne near theocean and collect on the camera even though ithas not been in direct contact with water.)Avoid excessive tightening when mounting ona tripod.

42

Avoid areas exposed to corrosive chemicals,radios, TV sets, or magnets.Have all repairs performed by an authorizedOLYMPUS Service Center. You may send itthrough the store where you bought your cam-era or directly to an Olympus Service Center.

PartsDo not press the shutter release button atrandom.Do not touch any part that moves at high speedsuch as the shutter, instant return mirror, dia-phragm, etc.

Avoid touching the surfaces of the lens. Cleanonly with an air blower, antistatic brush, or wipeit lightly with a camel hair brush or lens tissue.In EXTREME cases, use a clean, soft cottoncloth moistened with denatured alcohol. NEV-ER rub the lens surfaces with your finger, cloth-ing, or other abrasive material.If dust or fingerprints collect on the mirror,focusing screen, or prism, take the camera to anauthorized OLYMPUS Service Center. It needsprofessional attention.

QUESTIONS & ANSWERS

Q: My camera is loaded with film. Why doesn'tthe rewind knob rotate when I advance thefilm?

A: The film leader may not be inserted in thefilm take-up spool and the film is not ad-vancing. (See page 9.)

Q: Why can't I advance the film?A: The shutter may be cocked and ready to fire.

Try pressing the shutter release button. (Seepage 10.)Or, the film may be fully exposed. Check theexposure counter. If you feel tension on thefilm advance lever, DO NOT FORCE IT. Re-wind the film. (See page 20.) Or the self-timer lever is not securely in its upright posi-tion, reset and release the self-timer. (Seepage 21.)

Q: Why won't the shutter release button movewhen I press it?

A: The film advance lever may not have beenfully advanced. (See page 9.)

Q: I can't advance the film nor release the shut-ter, and the viewfinder is totally dark. Why?

A: The mirror is locked up because the batteriesare depleted or the film was advanced in themiddle of an automatic exposure. Press theselector lever to the "CHECK•RESET"posi-tion to unlock the mirror. (See page 8.) Twobatteries should be replaced as a pair if theyare depleted.

Q: Why won't the rewind crank turn when I tryto rewind the film?

A: The rewind release lever may not be rotatedin the arrow direction until it aligns with the"OM-2" marking. (See page 20.)

Q: Why can't I set the ASA film speed I need?A: At the most, 3 stops can be advanced in a

single stroke of the dial. If you require morestops, lift up and rotate the outer collar ofthe dial until it stops; then release the collarand reverse the collar and dial together untilthe white line is aligned with the black indexon the pentaprism. Repeat this procedureuntil you reach the ASA speed you need.(See page 11.)

44

Q: What batteries should I use?A: Use two 1.5V silver oxide batteries SR44

(Eveready EPX-76 or equivalents). Neveruse 1.3V mercury batteries (though theyare the same size). (See page 7.)

Q: Why doesn't the battery chamber cap fit?A: If you also own an OM-1, you may have the

caps mixed up. Although they look alike,the OM-2 cap has "2" engraved inside.

Q: When should I check the batteries?A: (1) When new batteries are inserted. (2)

After the camera hasn't been used for a longtime. (3) Before beginning a prolongedperiod of use.

Q: Can film be properly exposed when the selec-tor lever is in the "OFF" position?

A: The OM-2 is designed to always expose thefilm 1/30 second or faster (ASA 100) withthe selector lever at the OFF position. If theshutter is unintentionally released in darkercondition on "OFF" mode, the exposureautomatically stops in approx. 1/30 second(ASA 100) to save unnecessary battery ex-

haustion.

Q: Can I set the shutter speed ring to any posi-tion to take pictures on AUTO mode?

A: Any position except "B".Q: Why is the automatic exposure shutter speed

much longer than indicated by the meter inthe viewfinder?

A: If film is not loaded, the shutter speed ismuch longer than that indicated. If it isnecessary to obtain a correct reading with-out actually taking a picture, insert a waste,undeveloped film or the paper you find be-hind the camera back at the purchase of yourOM-2, into the film position in the camera.

Q: Can I use the exposure compensation dialwhen the selector lever is set at the "MAN-UAL" position?

A: Yes. If the exposure compensation dial isset for an intentional over- or under-ex-posure, that over- or under-exposure will beachieved when the shutter speed/F stopcombination centers the meter needle be-tween the over- and under-exposure indexmarks in the viewfinder. (See page 24.)

45

Q: How can I remove dust from inside the view-finder?

A: After detaching the Focusing Screen, blowaway any dust with an air blower. Neverwipe the screen surface with cloth or paper.(See page 28.) If this does not solve the pro-blem, send your camera to an authorizedOLYMPUS Service Center.

Q: Is it normal for the microprism in the centerof the viewfinder to "shimmer" and darken?

A: Yes, when a lens with a maximum aperturesmaller than F5.6 is mounted on the camera.It also happens with other lenses when thedepth of field preview button is pressed.

Q: Why does the self-timer stop halfway with-out releasing the shutter?

A: The lever will stop without releasing the shut-ter if the film has not been fully advanced.Reset the self-timer and make sure the filmis fully advanced. The self-timer lever movesfreely because you forget to turn the startlever after you set the self-timer lever. (Seepage 21.)

Q: Can I operate the camera without the motordrive socket cap in place?

A: No. Light will enter the camera body throughthis hole, fogging the film. Also, dust anddirt may enter, causing a camera malfunc-tion.

Q: Why doesn't my electronic flash unit firewhen I release the shutter?

A: If the shutter speed is 1 /125 second or fasterin conjunction with the electronic flash T32or T20, the built-in incorrect flash preventionsystem does not permit flashing. Confirmthe shutter speed. (See page 31.)

Q: Why do I feel a small electrical shock whenI touch the terminal contact of the accessoryshoe?

A: This is normal when using a side-mountingtype flash. When using flash that is not con-nected to the accessory shoe, remove orcover the shoe.

Before shutter release

The instant the shutter hasbeen released(A memory device controlsthe shutter speed, based onthe light reading taken beforeactual exposure.)

In the automatic mode, the OM-2 measures thesubject brightness very differently from any otherautomatic camera — faster and with much moreaccuracy. With the OM-2, light entering the lensis measured directly at the film plane by the sen-

MEASURING

Exposure range of OM-2 in automatic modeShutter Speed at F1.2

Exposure range of conventionalAE SLRs

Advantageous Points of Through-The-Lens Direct(off-the-film) Light Measuring Method1. The OM-2 sensors respond instantly to changes

in the light during exposure and feed back theinformation to the shutter control mechanism.

2. The sensors measure flash intensity as it buildsup and cut off its light at the source when thecorrect exposure level is reached. (TTL Cen-tralized Control Flash)

3. Even during 5-frame-per-second motor driveoperation, this Method insures correct ex-posure for each frame individually.

4. The Method operates accurately in far dimmerlight than other systems. ASA 100 film can

be automatically exposed for up to 120 sec-onds at F1.2.

5. The Method excludes all possibilities of straylight leaking through the camera eyepiece andaffecting the exposure reading.

6. The Method gives correct exposures even whenthe clear-field type focusing screen is in use.

OM SYSTEM

The OM System is comprehensively arrayed tomeet an ever-expanding universe of photographicconditions for any subjects from the stars to micro-organisms.A full-scale system camera is distinguishable bysome of the prerequisite characteristics as broad-ly mentioned below:

• Interchangeability of focusing screens.• Adaptability to high speed motor drive pho-

tography.• A wide range of high quality system compo-

nents, including interchangeable lenses.• Compatibility of the camera body with an

electronic flash unit allowing high technicflash photography with extreme ease andaccuracy.

• Tough and reliable shutter, viewfinder, etc.that withstand harsh handling without fail-ing.

When these exacting conditions have been satis-fied, an OM-2 is born as a true system camera thatcontrols an entire SLR comprehensive system. TheOM-2 is backed up with over 300 componentssystematically organized under eight groups — In-terchangeable Lens, Finder, Flash, Motor Drive,Phototechnical, Macrophoto, Photomicro andCase.

ZUIKO INTERCHANGEABLE LENS GROUP

One of many advantages of the single lens reflexcamera is the large variety of interchangeable lens-es available. The Zuiko Interchangeable LensGroup (designed and manufactured by Olympus)comprises 33 lenses. Zuiko lenses have always en-joyed a high reputation in photographic circles —the most modern design technology and employ-ment of newly developed optical glass have madepossible a new series of innovative, high perform-ance lenses. These lenses have a host of specialfeatures including new construction that compen-sates for close focus aberrations, increased aper-ture ratio in the wide angle lenses, and reductionin telephoto lens size and weight. The OM Sys-tem adopts 49mm filters for most lenses from21mm to 200mm. As part of the OM Systemdesign all the lenses now offer higher perform-ance in small configurations. Olympus has pro-duced lenses for microscopes for decades andthe new Zuiko lenses benefit from this scientificexperience. See the "OM System Zuiko Inter-changeable Lenses" manual for further in-formation.

In controlling contrastand eliminating unwanted hazein black and white photography,the use of the correct filter oftenmeans the difference between agood photograph and a great one.In color, where the balancing ofthe light with the film emulsionis absolutely necessary for cor-rect color, conversion and lightbalancing filters are the only ef-fective way of achieving the de-sired results.* Be careful not to use two filterssimultaneously in order to avoidunintentional cut in the per-iphery of a photograph.(See the table of various filterson the opposite page.)

FINDER GROUP

The viewfinder is one of the most important fea-tures of a single lens reflex camera. Since everyphotographic subject is turned into a visual imageby means of the finder, a finder that is dark ordifficult to look through is an obstacle to goodphotography. However enriched an SLR camerais with a wide range of interchangeable lenses, theSLR cannot be expected to fulfill its essential func-tion without the provision for changing of focus-ing screens. The OM-2 is provided with a view-finder that offers a far brighter, large image thanprevious 35mm SLR cameras. The Finder Groupsupplements this basic advantage with a compre-hensive set of 14 focusing screens for a wide varie-ty of applications from photomicrography to as-trophotography. Unless the most suitable focusingscreen for a given photographic purpose is avail-able, the potentialities of a system camera cannotbe utilized. For fast, accurate focusing, the OMSystem Finder Group offers the unique Vari-magni Finder with a magnification selector, theEyecup 1 that accepts a variety of DioptricCorrection Lenses, Eyecoupler, etc.

FINDER GROUP UNITS

Varimagni FinderThis unique and exclusive unitfor the OM System combinesthe two functions of angle finderand magnifier, incorporating 9lens elements and a reflector. Itfits over the camera's eyepiece,and can be adjusted for indi-vidual eyesight. Its eyepiece tubeis rotatable through 360°, for

use in low level and 90° angledshots. The two-stage, one-touchswitching system offers both a1.2x magnification image cover-ing the whole screen, and a 2.5xenlargement of the central por-tion for critical focusing. Forphotomicrographic use, insertthe Eyecoupler between the carp-era and Varimagni Finder.

Eyecup 1Attached by sliding over the OMBody eyepiece. Its rubber hoodprevents stray light from enteringthrough the eyepiece, an essen-tial requirement in light measur-ing. The Eyecup 1 is providedwith a slot for Dioptric Correc-tion Lenses.

EyecouplerConnects the Varimagni Finderto the OM Body for photomicro-micrography. It also ensures fullcoverage of the bright viewfinderfield for use of the Eyecup 1 inconjunction with the MotorDrive 250 Film Back.

Focusing Screen 1Interchangeable Focusing Screensare often thought of as a luxuryfeature in 35mm photography.Yet the Standard FocusingScreen 1-13 is often inconvenient

or difficult to use, and, in somecircumstances it is quite unsatis-factory. With super-telephotolenses for instance, the micro-prism becomes excessively dark.With the high magnifications ofmacrophotography and photo-micrography, it is impossible tofocus.The feature of each FocusingScreen is listed on pp. 59—60.

Dioptric Correction Lens 1Available in 8 diopter correc-tions: + 2, +1,0 (for hypermetro-pia); -1, -2, -3, -4, -5 (formyopia). Used to match thephotographer's vision, and espe-cially necessary in fine focusingfor high magnification. Fits intothe Eyecup 1.

SCREEN FEATURES

This screen is ideal for use with super telephoto tenses of 300mm ormore in focal length, or for astrophotography. The extreme finenessof the matte surface permits outstanding field definition. More accu-rate focusing may be achieved by the use of the Varimagni Finder.Designed for use with OLYMPUS fiberoptic endoscopes. This con-denser type screen without fresnel lens requires no focusing whena special adapter couples the camera with the fiberscope. Exposureis made automatically by the light supply.The grid lines engraved on the all-matte surface are used for verticaland horizontal picture alignment. Though originally designed forarchitectural photography with the Shift lens, it is also suitable forgeneral and super-telephotography, and close-up/macrophotographywith macro lenses and Auto Bellows.Highly advantageous for close-up and macrophotography with AutoBellows and extension tubes. For focusing in low magnification close-up photography, use the matte area and in macrophotography greaterthan life size, use the double cross hairs the same way as with the 1 -1 2.The meter needle indicates proper exposures, but depending on theconditions of the specimen, the reading must be compensated for.The transparent screen offers the photographer focusing with an un-usually bright finder image. To focus, first correct your diopterusing a dioptric correction lens or Varimag ni Finder so that eachline of the double cross hairs can be seen clearly and separately.Then bring the specimen into focus. The meter needle indicatesproper exposures, but depending on the specimen's conditions, thereading must be compensated for.Most suitable for normal photography, this screen assures pinpointfocusing. The central split image rangefinder is encircled by a micro-prism collar. Since the outer area has a matte surface, the screen canbe used in the same way as the standard 1-1 and 1-3 Screens. When alens with a maximum speed of F5.6 or slower is used, the prismsdarken and the focusing must be made on the matte area.Most suitable for normal photography. The central split-image rangefinder, encircled by a microprism collar, is inclined 45 degrees to alloweasy focusing on subjects with vertical or horizontal lines.

FLASH PHOTO GROUP

Flash is your own private "sun" when you takepictures at night, indoors, or outdoors for day-light fill-in. At the moment of flash, you can evencatch the movement of subjects that your owneyes are unable to follow.At present the OM System Flashphoto Group ren-ders choice of 5 different flash units, includingthe Electronic Flash T32 and T20. TheT32 offershigh performance — a maximum ASA 100 guidenumber of 32 (in meters) or 104 (in feet) with anangle that virtually covers the picture area of a24mm super-wide angle lens, and is provided witha built-in bounce mechanism. The T20 is extreme-ly compact and features a maximum ASA 100guide number of 20 (in meters) or 66 (in feet)with an angle that covers the picture area of a35mm wide angle lens. The T32 (or T20), whenused with the OM-2, is an OTF (off-the-film) ful-ly automatic electronic flash unit. Even the dialsettings (auto/manual switching, aperture settingand ASA film speed setting) required of conven-tional "auto" flash units are unnecessary. By re-versing the back plate of the flash unit, it can beused as a normal auto/manual flash unit for usewith the OM-1, permitting 3 aperture values ofF4, F5.6 and F8 (with T20, two apertures of F4and F8) at ASA 100 for normal auto flash as wellas two manual settings — GN16 (on T32 only)and GN32 (GN 20 with T20).

FLASH PHOTO GROUP UNITSTTL Centralized Control Flash by T32 (T20)/

OM-2 CombinationThe T32 (T20) utilizes the OM-2's own built-inSBC light sensors. The sensors read the build-upof light from the T32 (T20) which passes throughthe taking lens to reach the film surface, lettingthe electronic brain of the camera cut off theflash emission when the correct exposure has beenmade.On conventional auto flash units, the auto sensoris built into the flash unit. The sensor regulatesflash emission independently of the camera. Whilenormal auto flash units can also give a correct ex-posure, they are far less versatile and convenientin use. Their drawbacks include:

The need to set film speed and lens apertureon both the camera and the flash unit, which leadsto exposure errors caused by mistaken film speedand/or aperture alignment. With the T32 (T20)/OM-2 combination, once these values have beenset on the camera there is no need to reset themon the flash unit.

Restrictions on the f-number that can be used.With the T32 (T20)/OM-2, f-number can be

selected freely because the light is measuredthrough the camera lens.

Inability to change the light measuring angleof the sensor according to the taking angle of thechosen lens. With the T32 (T20)/OM-2, lightmeasuring angle always coincides with the picture

angle of the taking lens.Restricted close-up range and incompatibility

with extension tubes, etc. With the T32 (T20)/OM-2, close-up and diffused flash photographycan be made easily. As the exposure is calculatedinside the camera, the methods of using the flashunit are entirely unrestricted.

PHOTOTECHNICAL GROUP

As a leading manufacturer of optical instrumentsin various fields of modern life, OLYMPUS pro-vided the OM System with a wide variety of Photo-technical units, many of which can be used tosuccessfully document your valuable achievementsin photographs. This group includes a microscopeadapter for use with an operation microscope, anastroscope adapter to explore the mysteries ofspace and stars in conjunction with a telescope,etc., mostly capable of attaching on the OM body.Other outstanding advantages of this group arethe Recordata Backs 3 and 2 that are interchange-able with the OM standard camera back. Once inplace, the No. 3 Back automatically records thedate (year-month-day) or the time (day-hour-minute) in the lower right hand section of yourpicture (camera held in the horizontal position)simultaneously with the shutter release.Externally, data can be displayed on the liquidcrystal panel. Meanwhile, the No. 2 Back imprintsnumerical and alphabetical symbols in 4-dialcoding on the picture when the exposure is made,of great convenience in documentation, informa-tion filing, instant picture classification, etc. BothBacks can be used for high speed motor drive pho-tography and flash photography.For Olympus Pen F and FT enthusiasts, a mountadapter is also available for connection of thesecameras to the OM System interchangeable lensesand other unit

PHOTOMICROGRAPHY GROUP

When the photographic magnification desired ex-ceeds 10x, it becomes more difficult for the macro-photographic equipment alone to obtain excellentpictures. A sophisticated array of photomicro-graphy accessories with a microscope as the cen-tral figure is required. The exciting vision of look-ing at the microscopic world through a microscopecan be recorded by the OM-2.OLYMPUS has an outstanding reputation formanufacturing precision microscopes used byscientists throughout the world. Naturally, theOM System includes a variety of microscopeadapters, rugged stands, a special shutter to pre-vent vibration at high magnification, and an auto-matic exposure mechanism which solves the dif-ficult problem of microscope exposures.The Photomicrography Group is designed to ex-pand the photomicrographic world not only intothe scientific realm, but also into the creativesphere, so that the photographer's achievementsunder the microscope can be easily and accuratelyrecorded with his OM-2.
