Align the red dots on the lens flange and the body mount ring. Turn the lens clockwise until the lens release button springs up and you will hear positive "click". Insert two 1.5V silver oxide batteries SR44 (Eveready EPX-76 or equivalents) into the battery chamber. CAUTION: Batteries should be always replaced as a pair. If battery polarity is incorrect, the camera does not function. Lens Removal To detach the lens, press down on the lens release button and turn the lens counter-clockwise. Always attach the front and rear lens caps when the lens is removed from the body to prevent any possibility of damage. 7 BATTERY CHECK AND MIRROR LOCK-UP a point to switch off the selector lever when the camera is not used. By pressing the selector lever to the "CHECK· RESET" position, you can check the batteries Mirror Lock-Up If the mirror is up, the field of view turns dark through the viewfinder, and the film cannot be advanced. This lock-up of the mirror occurs when and/or unlock the mirror. Check the Batteries. Move the selector lever to the "CHECK·RESET" no batteries are loaded or batteries are depleted, or the film is advanced during exposure. The mirror lock-up does not indicate any breakdown of the camera, but a built-in safety device position. The battery check lamp indicates battery condition as follows: The red lamp lights brightly -- Battery voltage is sufficient. The red lamp flashes on and off -- Batteries are very weak. Fresh batteries are recommended. The lamp does not light -- Batteries are drained. Replace them. NOTE: Silver oxide batteries will last approximately one year. To avoid battery drain, make it to prevent any trouble. Press the selector lever to the "CHECK·RESET" position, and unlock the mirror. In case , shooting can be resumed immediately. In case , replace batteries. CAUTION: You cannot unlock the mirror after battery replacement, if you omit pressing the selector lever to the "CHECK·RESET" position. NOTE: When the mirror locks up, a battery drain prevention device is activated to conserve power. 8 LOADING THE FILM Pull the rewind knob up and open the camera back. Insert a film cartridge into the film chamber and push the rewind knob back. Turn the advance lever so that the film perforations engage the sprocket teeth. Close the camera back until it clicks. Make sure the selector lever is in the OFF position. NOTE: Fold out the rewind crank and rotate it clockwise slightly to remove any slack in the film. Then if the rewind crank rotates as you turn the advance lever, the film is properly advancing. Insert the film leader into one of the slots in the film take-up spool. 9 OPERATING THE FILM ADVANCE LEVER EXPOSURE COUNTER Turn the advance lever to the right as far as it will go. The film can be advanced by one frame, in a single stroke or in multiple short strokes. NOTE: If the advance lever stops moving because you've shot the last remaining film frame while you are advancing the film, discontinue the film Exposure Counter The 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, the exposure counter automatically returns to "S". advance and rewind the film. (Read pages 37~41 for motor drive shooting.) 10 SETTING THE ASA FILM SPEED DIAL Lift up the outer collar of the exposure compensation dial and rotate until the ASA speed for the film appears in the window. Once the setting has been made, turn the dial until the white line is aligned with the black index line on the pentaprism housing. CAUTION: Make sure you align the white line with the black index line on the pentaprism after setting ASA. The ASA film speed scale on the dial is marked from 12 to 1600. If you are not able to rotate the outer collar to the desired ASA in one turn of the dial (only 3 stops can be rotated in one turn of the dial), release the collar and turn the exposure compensation dial several click stops in the opposite direction from the ASA you are trying to set. Then, lift the outer collar again and continue turning to the desired ASA setting. NEVER FORCE THE DIAL THE MEMO A memo holder provided on the camera back accepts a HOLDER memo slip or the end flap from most 35mm film packages as a reminder of ASA, exposure number, etc. 11 WHEN SETTING ASA. APERTURE RING AND MANUAL SHUTTER SPEED RING Aperture Ring The opening (aperture) in the lens diaphragm is marked in F stops on the aperture ring. The higher Manual Shutter Speed Ring Shutter speeds engraved on the manual shutter speed ring are used only for non-automatic camera operation. B indicates "bulb" at which setting the shutter will remain open as long as the shutter release button is held down. The other engravings indicate fractions of a second; for example "T" for 1 second, "2" for 1/2 second ..... the F number, the smaller the lens opening (less light) and provides greater depth of field than lower F numbers (see page 25). When setting the aperture ring, you may use either the click-stop positions or any in-between settings to obtain precise exposure control. NOTE: All lenses in the OM System (except certain specialized lenses) provide fully automatic diaphragm control allowing you to focus and compose your picture with the lens fully open. The diaphragm will automatically close to the up to "1000" for 1 /1000 second. To set at "B", rotate the ring while pressing the B LOCK button at the lower left of the body mount. Be careful that shutter speeds are set only at click stop positions. Make sure that the selector lever is set at a click stop position. 12 pre-selected F stop at the moment of exposure. And immediately re-open after exposure. SETTING THE SELECTOR LEVER VIEWFINDER AUTO OFF MANUAL The selector lever on top of your camera has four positions as follows (with click stops at AUTO-OFF-MANUAL): The three-position viewfinder control center allows you to see the operating mode of your camera without checking the position of the 1) AUTO -- Automatic exposure control; you preset the F stop and the camera automatical- selector lever. NOTE: If you release the shutter with the selector lever at OFF in normal lighting condition, the built-in automatic exposure control is activated to take a properly-exposed picture, so as not to miss optimum exposure opportunity, at any mo- ly sets shutter speed for proper exposure. 2) OFF -- Camera turned completely off to avoid battery drain. Always store your camera with the selector lever in this position. 3) MANUAL -- Zero-method exposure operation; set shutter speed and F stop for proper exposure (see page 17). ment. The difference between the automatic exposures in the OFF position and the AUTO position, however, is that the OFF mode exposure 4) CHECK·RESET -- Battery test position simultaneously with release of mirror lock-up. 13 stops in 1/30 sec. maximum to save battery exhaustion, and the AUTO viewfinder scale does not appear. FOCUSING In focus. Look through the viewfinder and turn the focusing ring in either direction until your subject appears sharpest. The split image will be vertically aligned in the central spot of the Focusing Screen or a shimmering effect of the microprism ring around Out of focus. the central spot will disappear when critical focusing has been achieved. NOTE: You can determine the distance between the subject and the film plane by reading the distance scale on the focusing ring after setting critical focusing. The actual distance is indicated opposite the red central index mark on the lens mount ring; the white scale indicates this distance in meters and the orange scale in feet. Microprism Ring Rangefinder Spot Matte Field (For Focusing Screen replacement read pages 28, 59 and 60). 14 AUTOMATIC EXPOSURE CONTROL Red Zone Blue Zone The Aperture-Preferred System LEASE THE SHUTTER. NOTE: At shutter speeds slower than 1/60 second, The aperture-preferred system is the most convenient and easy-to-use method of automatic operation, particularly outdoors when using 50mm or wide-angle lenses. To use this system: Set the selector lever to the "AUTO" position making sure that the lever "clicks" into place. Set the F stop you wish to use on the lens the possibility of camera movement during exposure is increased. If the needle in the viewfinder indicates a shutter speed in this area, turn the aperture ring to the left (so as to open the aperture). For use of interchangeable lenses of various angles of view, refer to the data below to determine the hand-held shutter speed and avoid blurry pictures: Wide-angle and super wide-angle lenses -- 1/30 aperture ring. The camera will automatically determine the shutter speed required for proper exposure and indicate that speed in the viewfinder. Then RE15 second or faster. 50mm lenses -- 1/60 second or faster. Telephoto and Zoom lenses to 100mm -- 1/125 second or faster. Telephoto and Zoom lenses to 200mm -- 1/250 second or faster. Super telephoto lenses of 300mm and up -- 1/500 second or faster. If the viewfinder needle enters the red zone Warning against over-exposure. A shutter speed faster than 1 /1000 second is required for proper exposure, but the shutter will be released at 1/1000 second. Since this is beyond the range of your OM-2 and an overexposed photograph would result, turn the lens aperture ring to a higher F stop until the meter needle moves out of the red zone. If the viewfinder needle enters the blue "AUTO" zone Indication for long time exposure. A shutter speed longer than 1 second is required for proper exposure. Your OM-2 provides for automatic exposures from 1 second to 120 seconds (with ASA 100 at normal temperature and humidity). If you wish to close the shutter during a long time exposure under AUTO operation, turn the selector lever to the OFF position, and the shutter closes. CAUTION: Do not advance the film while the mirror is up during an automatic exposure, or the mirror will lock up. The Shutter Speed-Preferred System Should you wish to select a shutter speed to meet a specific photographic situation (e.g., stopping fast action, eliminating camera movement or controlling depth-of-field), you may use a shutter speed-preferred method of automatic exposure control. To use this system: Set the selector lever to the "AUTO" position. Look through the viewfinder and turn the aperture ring until the viewfinder needlepoints at the desired shutter speed. 16 MANUAL EXPOSURE CONTROL Set the selector lever to "MANUAL", and the exposure index marks and Aperture-Preferred Manual Exposure Control Turn the aperture ring until the desired F stop is opposite the white index mark. the meter needle are visible in the viewfinder. Shutter Speed-Preferred Manual Exposure Control 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. Should you wish to preselect a shutter speed turn the shutter speed ring until the desired speed is opposite the red reference dot on the Make sure that the shutter speed ring is clicked into position and not between two settings. Make the final exposure adjustment by turning the aperture ring until the needle aligns exactly in the center of the index. CAUTION: The shutter speed thus obtained should meet the other photographic conditions properly, especially at "B" where the shutter speed ring is not coupled with the exposure meter. lens barrel (see page 12). Look through the viewfinder and turn the aperture ring until the needle lines up in the center of the index. For fine exposure adjustment you can use any click-stop or intermediate F stop position. 17 ASA 100 50mm F1.8 lens, fully opened 50mm F1.4 lens, fully opened 1/2 sec. Exposure Meter Needle Exposure Meter Index ASA 100 1/2 sec. ASA 100 55mm F1.2 lens, fully opened 1/2 sec. If the Exposure Needle Does Not Center on the Index If an exposure or a shutter speed is improperly selected, the exposure needle will not center on the index. Reset the shutter speed or F stop until the needle is centered. You may use an ND (neutral density) filter if the subject is too bright, or an electronic flash or flash bulb if the subject is too dark. Light Measuring Range of the Exposure Meter The measuring range is EV 1.5-EV17 (ASA 100, with F1.2 55mm lens). The list above summarizes the lowest measurable limits in dealing with extreme low light conditions. CAUTION: If the aperture ring or shutter speed ring 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 not functioning. 18 HOLDING THE CAMERA Proper camera handling is important in assuring the sharpest possible pictures. Holding the Camera Horizontally Keep both elbows close to the body, to steady the camera. Putting the Camera into Operation The aperture ring, focusing ring and shutter speed Holding the Camera Vertically For vertical shooting, keep one elbow close to your body and press the camera tightly against your forehead. NOTE: Steady yourself against any nearby support (such as a tree, fence, or wall) whenever possible. ring are so arranged as to enable one hand operation right up to the moment the shutter is released. Hold your breath at the moment of shutter release. Transport the film advance lever with your right thumb and squeeze the release button smoothly using the cushion, not the tip, of your index finger. 19 NOTE: For telephotography, or slow shutter speed photography, it is recommended that you use a tripod and hold the camera steady with your hands. UNLOADING THE CAMERA MAKING MULTIPLE EXPOSURES Should you wish to make more than one exposure on the same frame: Take up any slack in the film by slowly turning the rewind crank in a clockwise direction until it stops, then take the first exposure. Turn the rewind release lever counter-clockwise by about 90°. Hold both the rewind knob and rewind release lever to prevent them from turning and advance the film advance lever. The shutter will then be cocked for the next exposure without advancing the film. Press the shutter release button with a slow, steady squeeze. When the entire roll of film has been exposed rewind the film. Turn the rewind release lever counter-clockwise by about 90°. Fold out the rewind crank and wind it in the direction of the arrow. While rewinding, you will feel tension on the crank. When the tension stops and the crank turns freely, the film has been completely rewound back into the cartridge. The exposure counter will advance with each exposure. After completing the multiple exposures, put the lens cap on the lens, advance the film, and shoot a blank frame to avoid overlapping. NOTE: You can make as many multiple exposure as you like by repeating the above procedure. With each exposure on the same frame, the possibility of slippage is increased. Open the camera back by pulling up on the rewind knob and remove the film cartridge. Keep camera and film out of direct sunlight while unloading. 20 SETTING THE SELF-TIMER Rotate the self-timer lever counter-clockwise Stopping the Self-timer To stop the self-timer during its operation, turn so that the shutter can be released after an elapse 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 before or after advancing the film. Turn the start lever clockwise to the vertical position to activate the self-timer lever. The shutter will then be released after the preset time. the start lever counter-clockwise. If you turn the start lever clockwise again, the self-timer can resume its action. NOTE: After setting the lever, you can release the shutter by pressing the shutter release button. 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. If the film has not been advanced fully, the timer lever will stop half-way. To re-activate the timer, move the start 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. 21 EXPOSURE COMPENSATION After compensation After compensation Before compensation When the most important area of the picture is much darker than the general picture area (blue sky, snowfield, etc.), the meter will have a tendency to read the brightest part of the picture leaving the main subject under-exposed. Alternatively, when taking a picture of a bright subject against a dark background the meter tends to read the darkest part Before compensation leaving the main subject over-exposed. In these situations, proper exposure compensation helps you take fine pictures. NOTE: With backlighting or sidelighting it's always a good idea to use a lens hood to eliminate unwanted glare. 22 EXPOSURE COMPENSATION FOR AUTOMATIC MEASUREMENT If you wish to change the exposure setting automatically selected by the camera, use the exposure compensation dial and a compensation marker appears in the viewfinder. When the main subject is much darker than the general background or when strong light strikes the subject from behind or from the side, turn the dial to the (+) side. Turn the camera to the subject so that the subject fills most of the viewfinder, or move the camera toward the subject. After reading the shutter speed, return to the original position and rotate the compensation dial until the meter needle points at the read-out speed in the finder. NOTE: In such a case it is recommended to turn the compensation dial to the + 1 side. When taking a picture of a bright subject against a dark background (spotlightng, deep shadows, etc.), turn the compensation dial to the (--) side. Move forward until the subject fills as much of the viewfinder as possible, (with a zoom lens, you may be able to do this by zooming in on the subject without chaning your positions). After noting the shutter speed indicated by the meter needle, return to your original position, recompose the picture, and turn the compensation dial until the shutter speed needle indicates the speed obtained from your close-up meter reading. 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 adjusting the F stop or shutter speed. The exposure needle indicates over-exposure at the (+) side, or position and take the picture without changing this F stop/shutter speed combination even though the needle is not centered. NOTE: Over-exposure by + 1 stop renders a good result in such a case. under-exposure at the (--) side. Dark subject in bright backlighting When the most important area of the picture is much darker than the general picture area (strong light hitting the main subject from behind or from Bright subject in dark background As previously mentioned, fill the viewfinder pic- the side) the meter will have a tendency to read the brightest part of the picture leaving the main subject under-exposed. To compensate for this, move forward until the subject fills most of the viewfinder picture area and set the F stop/shutter speed combination which centers the meter needle ture area with the subject as much as possible, and set correct light measurement. Return to your original position and expose for fine pictures. CAUTION: After taking a picture using the compensation dial, be sure to return the dial to the normal setting between the index marks. Return to your original 24 DEPTH OF FIELD (e.g. from F2.8 to F16) or getting farther away from your subject this depth of field can be increased. The table below shows that when the camera- to-subject distance is 3m, the depth of field at F16 ranges from 1.93m to 6.93m. As you press the preview button, looking through the viewfinder, you can ascertain the actual depth of field. F16, 1/15 sec. Depth of Field Table (F1.8 & F1.450mm Lenses) Circle of least confusion 1 /30mm F2, 1/1000 sec. Depth of field is the area of acceptable sharpness in front of and behind the subject in focus. As you get closer to your subject or as you open your lens (e.g. from F16 to F2.8) the depth of field becomes shallower. By stopping your lens down 25 DEPTH OF FIELD SCALE PREVIEW BUTTON The double series of numbers engraved on the depth of field scale represents F stops: F4, F8, and F16. Once you have focused on your subject, all objects within the distance range indicated on the lens distance scale between the marks for the F stop 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. If you read the distance scale at the points opposite 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.). 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 viewfinder. CAUTION: If you jerk the preview button while depressing the shutter release button halfway down the shutter might be released. 26 INFRARED PHOTOGRAPHY CAMERA BACK REPLACEMENT The OLYMPUS OM System Lenses are provided with an infrared index mark engraved in red on the depth of field scale. When shooting with infrared film, focus normally on your subject without the red filter on and read The camera back of the OM-2 is fully interchanbe- able with the Recordata Back 2, 3 and 250 Film Back 1. To remove the camera back, push down on the release pin as shown. Do not remove the back unless necessary. The Recordata Back 2, 3 registers data such as date, number, alphabetical code, etc. directly on the picture. the subject distance on the distance scales. Then, turn the focusing ring to the right until the distance reading is opposite the infrared index mark. Your lens will then be in focus for average infrared photography. Shoot with the red filter on. In the above picture, the red index is set at infinity. CAUTION: Due to special light gathering requirements of infrared films, it is recommended that you follow the film manufacturer's recommendations regarding exposure. The 250 Film Back 1 is designed for winder or motor drive shooting; it accepts a bulk loaded magazine of 250 frames. 27 INTERCHANGEABLE FOCUSING SCREENS The OM System interchangeable focusing screens provide you with the ultimate in focusing versa- CAUTION: Although the above procedure can be done with fingers, it is recommended that you tility. Optional screens are available to suit virtually every picture-taking situation. The focusing screens come with a special tool. To remove the focusing 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 of the mirror box (see the photo above). This allows the screen and screen frame to drop down. c) Remove the screen from inside the camera by gripping the tip of the screen with the tool as shown. use the special tool supplied. Changing focusing screens is a procedure to be exercised with great care. Trying to change a screen with your fingers can result in fingerprints and costly damage to the surface of the screen, the prism, or the mirror. Should this occur, cleaning or repair MUST be handled by an authorized service center. Such damage is not covered by the product warranty. d) To install the screen, fit it into the frame and push the frame upward gently until it clicks into place. Gently shake the camera body to make sure the screen is held securely in place. 28 FLASH PHOTOGRAPHY WITH THE T32(or T20) ELECTRONIC FLASH Electronic Flash T32 Electronic Flash T20 T32 calculator panel (blank side for TTL "OTF" Auto flash) The T32 and T20 are the world's first fully automatic electronic flash units. All their functions are controlled directly by the OM-2 to perform ex- tremely easy, yet highly accurate flash exposures. (See pp. 61~69 for further information on flash units.) 29 Attach the Accessory Shoe 4 to the OM-2 and mount the T32 (or T20). Set the camera's selector lever to the "AUTO" position and switch on the T32 (or T20). NOTE: Mounting the T32 (or T20) on the accessory shoe automatically completes the "X" synchro circuit. It is not necessary to set the X and FP flash selector to "X". A red lamp lights in the viewfinder when the T32 (or T20) capacitor is charged ready for shooting. 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 be used. 30 FLASH PHOTOGRAPHY WITH THE T32 (or T20) ELECTRONIC FLASH Light Blue If the lamp flickers: correct flash exposure has been made. If the lamp goes out: flash-to-subject distance is beyond the TTL AUTO working range. Open up the lens stop or move in closer to the subject. If the lamp stays lighted: correct exposure has been made by existing light, requiring no flash. In case exposure must be achieved by flash illumination, turn the aperture ring until the meter needle points to 1/30 sec. or slower, and shoot. NOTE: The OM-2 incorporates an incorrect flash prevention system. If the shutter speed is faster than the flash synchronizing range, the electronic flash will not fire when you press the shutter release button. 31 THE T32(T20)/OM-2 WAY--FLASH PHOTOGRAPHY COULDN'T BE SIMPLER AND MORE ACCURATE T32 (T20) and OM-2 (TTL Centralized Control flash operation) Ordinary electronic flash unit and camera (Normal automatic flash operation) Picture angle = Light measuring angle All required of the T32 (T20) is a flick of the on/ off switch. The rest is taken care by the OM-2. The dial settings required of conventional "auto" flash units -- ASA film speed setting, aperture setting, flash mode switching, exposure compensation -- are not needed with the T32 (T20). Unlike conventional auto flash units which regulate flash emission by an independent light sensor, the T32 (T20) utilizes the OM-2's own builtin SBC light sensors, so that flash acceptance angle always coincides with the picture angle of the camera lens. The OM-2 shutter automatically closes at the instant the flash exposure has been completed. Picture angle Light measuring angle eliminating camera shake. Correct exposure can be confirmed without taking your eye off the viewfinder. By the incorporation of an incorrect flash prevention system, the electronic flash will not fire if the shutter speed is faster than the synchronizing range. Special techniques such as diffused lighting are made easy, obviating complicated compensations and guesswork. Usable flash-to-subject distance range is greatly expanded - 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 of 104 at ASA 100.). 32 BOUNCE FLASH The T32 flash surface can be tilted upward through Point the flash surface at the ceiling so that an angle of 90°, providing easy bounce TTL Auto flash. the subject is illuminated by soft reflected light. 33 CLOSE-UP FLASH Close-up in TTL Auto flash can be achieved simply by tilting the flash surface downward (up to 15°). 34 FLASH PHOTOGRAPHY WITH AN ELECTRONIC FLASH UNIT OTHER THAN THE T32-T20 Attach the Accessory Shoe 4 to the OM-2.
