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 me ...
