Make sure the battery has been properly inserted and that the camera back is closed tightly. Set ASA Film Speed (see page 12). Advance the film until the figure "1" appears in the exposure counter window (see page 9). Look through the viewfinder. Compose and focus. Set the prop- er exposure (see pages 13, 14, 15). Take the picture (see page 19). Hold the camera steady and release the shutter with a slow, steady pressure. 6 After the entire film has been exposed, rewind the film back into the cartridge (see page 10). INSERTING THE BATTERY LOADING THE FILM FRONT LENS CAP The OLYMPUS OM-1 is supplied with a 1.35V mercury battery (JIS H-D type) to power its through-the-lens exposure metering system. It will last approximately one year depending upon use and must be replaced with an Eveready (UCAR) EPX625, Mallory PX625 or equivalent. Substitutes must not be 1. Open the camera back. Pull up on the rewind knob. A slight resistance may be felt before the camera back snaps partially open. 2. Load the camera. Insert a film cartridge in the film chamber and push the rewind knob back into its original position. It may be necessary to turn the rewind knob slightly before it will lock securely in place. used. (NOTE; The exposure meter stops functioning when the battery runs out. To prolong battery life, make sure the Meter Switch Lever is in the "OFF" position when the camera is not in use.) To insert the battery: 1) Insert the edge of a coin into the cap of the battery chamber and turn counter-clockwise until the cap has been removed. 2) Place the battery in the battery chamber making sure the positive side (+) is facing out. The exposure meter does not function if the battery is inserted incorrectly. 3) Replace the cap tightly. 7 3. Attach the film end to the take-up spool. Draw out the film leader and insert it into one of the slots in the film take-up spool. Make sure the film is evenly placed between the film guide pins. Be careful not to permit the film leader to protrude out of the opposite slot when inserted into the spool. 4. Advance the film. Advance the film using the film advance lever. Make sure that the film perforations engage on the sprockets on both sides. 7. Check the exposure counter window. Advance the film and depress the shutter release button. Advance the film once more until "1" appears in the exposure counter window. The rewind knob will rotate in a counterclockwise direction indicating that the film is advancing properly. 5. Close the camera back. Close the camera back until it clicks into place. To attach or remove the front lens cap, press the spring-loaded lens cap retaining clips on either side of the cap. The 6. Tighten the film. After closing the cover, fold out the rewind crank and turn it slowly in a clockwise direction until a slight resistance is felt. This will take up any slack in the film. cap then fits easily over the accessory thread of the lens. 8 OPERATING THE FILM ADVANCE LEVER THE EXPOSURE COUNTER In one stroke the film advance lever: 1) advances the film one full frame, 2) advances the exposure counter, 3) cocks the shutter, 4) sets the instant return mirror, 5) activates the automatic diaphragm mechanism and 6) activates double advance and To advance the film: 1) Gently pull the film advance lever away from the camera body. 2) Advance the lever to the right as far as it will go. This can be accomplished in a single stroke or in multiple short strokes. double exposure nism. prevention mecha- The exposure counter is designed to indicate the total number of frames exposed on the film. Each time the film is advanced by the film advance lever, the exposure counter automatically adds one frame to the total. The counter is indexed in even numbers up to 36 plus "S" (start) and "E" (end). For easy reference, "S", "E", and numbers 12, 20 and 36 are indicated in gold. Whenever the camera back is opened, the exposure counter automatically returns to "S". Refer to page Photography. 21 for Motor Drive 9 UNLOADING THE FILM When the entire roll of film has been exposed (indicated by numbers 12, 20 or 36 on the exposure counter depending on film length), rewind the film. 1) Turn the rewind release lever counter-clockwise until the red line is opposite the "R". 2) Fold out the rewind crank and wind it in the direction of the arrow. During the rewind procedure you will feel tension on the crank. When it turns free the film has been completely rewound back into the cartridge. 3) Open the camera back by pulling up on the rewind crank and remove the film cartridge. Keep camera and film out of direct sunlight. IMPORTANT: Do not force the film advance lever if the film has been fully exposed. If there is some resistance, rewind the film to prevent tearing. posure, cover the lens with a lens cap, advance the film and shoot a blank frame to avoid overlapping. You can make as many multiple exposures as you like by repeating the above procedure. With each exposure on the same frame (the exposure counter adds one), the likelihood of slippage is increased. Practice is required in order to obtain good results. MAKING DOUBLE EXPOSURES Should you wish to make more than one exposure on the same frame: 1) After taking the first exposure, turn the rewind knob slowly in a clockwise direction until it stops to take off any slack in the film. 2) Turn the rewind release lever counter-clockwise until the red line is opposite the "R". 3) Hold both the rewind knob and rewind release lever firmly to prevent them from turning and advance the film advance lever. The shutter will then be cocked for the next exposure of the frame, without the film being advanced. 4) Depress the shutter release button with a slow, steady pressure. 5) After completing the multiple ex10 SETTING THE SHUTTER SPEED RING SETTING THE APERTURE RING The length of time that light is allowed to strike the film is controlled by the focal plane shutter. The shutter consists of two opaque "curtains" which travel across the opening and allow light to reach the film. The speed and coordinated movement of these curtains determine in fractions of a second the exposure time for your picture. For example, 1000 on the shutter speed ring indicates 1/1000 of a second and 60 indicates 1/60 of a second. The figure 1 indicates one full second. The B (Bulb) setting is used for longer time exposures. At this setting the shutter will remain open as long as the shutter release button is held do ...
