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 two silver oxide batteries SR44(Eveready EPX-76 or equivalents) into the bat-tery : Batteries should be always replacedas a pair. If battery polarity is incorrect, the cam-era does not CHECK AND MIRROR LOCK-UPa point to switch off the selector lever when thecamera is not pressing the selector lever to the "CHECK RESET" position, you can check the batteriesand/or unlock the the the selector lever to the "CHECK RESET"position.

Fresh batteries are lamp does not Light Batteries are drain-ed. Replace : Silver oxide batteries will last approxi-mately one year. To avoid battery drain, make itMirror 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 whenno batteries are loaded or batteries are deplet-ed, or the film is advanced during 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.

(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 DIALLift up the outer collar of the exposure com-pensation dial and rotate until the ASA speedfor the film appears in 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.

8 Then, lift the outercollar again and continue turning to the desir-ed ASA setting. NEVER FORCE THE DIALWHEN SETTING the setting has been made, turn the dialuntil the white line is aligned with the blackindex line on the pentaprism : Make sure you align the white linewith the black index line on the pentaprismafter setting MEMOHOLDERA memo holder pro-vided on the cam-era back accepts amemo slip or theend flap from most35mm film packagesas a reminder ofASA, exposure number, RING AND MANUAL SHUTTER SPEED RINGA perture 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 : 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 diaphragm will automatically close to thepre-selected F stop at the moment of immediately re-open after Shutter Speed RingShutter speeds engraved on the manual shutterspeed ring are used only for non-automatic cam-era operation.

9 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 careful that shutter speeds are set only atclick stop positions. Make sure that the selectorlever is set at a click stop THE SELECTOR LEVERThe selector lever on top of your camera has fourpositions as follows (with click stops atAUTO-OFF-MANUAL):1) AUTO Automatic exposure control; youpreset the F stop and the camera automatical-ly sets shutter speed for proper ) OFF Camera turned completely off to avoidbattery drain. Always store your camera withthe selector lever in this ) MANUAL Zero-method exposure operation;set shutter speed and F stop for proper ex-posure (see page 17).

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 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 : 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.
