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 down. For exposures less than 1/30 of a second, it is advisable to use a cable release, tripod or other steadying devices to avoid camera movement which can result in blurred or fuzzy pictures. To set the shutter speed turn the shutter speed ring in either direction until the desired number clicks into place opposite the reference dot on the lens barrel. Set the ring only at clickstop positions as no in-between settings can be used. Shutter speeds may be set before or after advancing the film. NOTE: Speeds from "B" to "60" are indicated on the ring in blue as an easy reference to "X" flash synchronization. The amount of light allowed to strike the film is represented by "F" numbers or "F" stops engraved on the aperture ring. The higher the F number, the smaller the lens opening (less light); the lower the number, the larger the lens opening (more light). When setting the aperture ring you can use either the click-stop positions or any in-between settings to obtain precise exposure. All lenses in the OLYMPUS OM SYSTEM (other than specialized lenses) provide fully automatic diaphragm control allowing you to focus and compose your picture with the lens at maximum aperture or "wide open." The diaphragm will automatically stop down to the preselected F stop at the moment of exposure and immediately re-open when exposure is completed. 11 SETTING THE ASA FILM SPEED DIAL THE METERING SYSTEM Setting the correct ASA film speed on the camera is one of the most important factors in determining exposure. 1) Pull the film advance lever slightly away from the camera body. 2) Press the film speed dial release The OLYMPUS OM-1 incorporates a built-in, wide-open exposure metering system which uses two highly sensitive In order to obtain properly exposed pictures, the correct ASA film speed must be set on the ASA film speed dial. To set the dial: button and turn the film speed dial until the ASA rating for the film being used is opposite the black line engraved on the outer ring of the shutter release button. 3) Release the button making sure that the dial is securely in place and does not move. CdS cells with one postioned on each side of the eyepiece. These cells measure the actual amount of light entering the lens, placing the greatest emphasis at the center of the picture area. Measurements are taken with the lens diaphragm at maximum aperture (wide open) allowing you to take full advantage of a brighter viewfinder when focusing and composing your picture. The OM-1 metering system operates as above with all OM System camera lenses (except a few special lenses) regardless of the focal length, filters, etc. 12 SETTING THE EXPOSURE Exposure Meter Needle Exposure Meter Index Activating the Meter Preselecting the Shutter Speed The OLYMPUS OM-1 metering system is directly coupled to the shutter speed ring, aperture ring and ASA film speed dial. To activate the meter, move the meter switch lever at the top of the camera to the "ON" position. To prolong battery life, it's a good idea to return the lever to the "OFF" position when the camera is not in use. Should you wish to select a shutter speed to meet a specific photographic situation (for example, to stop fast action, eliminate camera shake, etc.): 1) Turn the shutter speed ring until the desired speed is opposite the red reference dot on the camera lens. 2) 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 intermediate F stop position on the aperture ring. 3) If the needle will not align properly, select a new shutter speed. To correct over-exposure (+), try a faster speed; to correct under-exposure ( ­ ) , try a slower speed. Preselecting the F Stop Should you wish to preselect the F stop (for example, to control depth of field for greater creative impact): 1) Turn the aperture ring until the desired F stop is opposite the white index mark at the front of the lens barrel. 2) 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. Make sure that shutter speed meets the other requirements of the situation. 3) Make the final exposure adjustment by turning the aperture ring slightly until the needle aligns exactly in the center of the index. 13 Below this limit or with the meter switch at OFF, when the aperture ring or shutter speed ring is rotated, the needle might sometimes swing but the meter will not work. Lens 50mm F1.8 50mm F1.4 55mm F1.2 F/Stop Fully open Fully open Fully open Shutter Speed read the brightest part of the picture leaving the main subject under-exposed. To compensate for this, move in towards the subject until most of the subject image appears in the viewfinder and take your meter reading. After setting the exposure, return to your original position to take the picture. If this procedure cannot be followed, you can obtain approximately the same results by simply opening your lens one full F stop over the indicated meter reading. (NOTE: With backlighting or sidelighting, it's always a good idea to use a lens hood to eliminate unwanted glare.) 2) Strong Frontlighting and Deep Shadows When taking a picture of a bright subject against a dark background (spotlights, deep shadow areas, etc.) the meter has a tendency to read the darkest part of the picture leaving the main subject over-exposed. To compensate for this use the same procedure for setting exposure as outlined for backlighting. You can also approximate the proper exposure by holding your position and closing the lens down one full F stop from the indicated meter reading. 1/2 sec 1/2 sec 1/2 sec Stop-down Exposure Readings Making Intentional Over- or Underexposures You can make intentional over- or under-exposures to meet special lighting requirements (such as backlighting, sidelighting, etc.) by using the central index in the viewfinder as a guide. When the needle swings towards the (+) position, it indicates over-exposure. When it swings towards ( ­ ) , it indicates under-exposure. The exact F stop-needle relationship is shown in the above diagrams. Caution in Low-light Exposure Metering The meter's exposure range is EV2--17 (ASA 100 with F1.4.) The combinations listed below indicate the lowest measurable limit in dealing with dark subjects. When using the OM-1 in conjunction with the extension tubes, bellows or the Zuiko Shift Lens it is necessary to take meter readings with the lens stopped down. After setting the desired aperture on the aperture ring, stop the lens diaphragm down and look through the viewfinder. Rotate the shutter speed ring until the needle aligns within the center of the index. (See the instructions on Preselecting the F Stop, page 13.) Special Exposure Techniques 1) Backlighting and Sidelighting 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 the side) the meter will have a tendency to 14 FOCUSING The OLYMPUS OM-1 comes equipped with the standard Focusing Screen 113 (microprism/split image-matte type) which is designed to make focusing quick and easy. To focus, look through the camera viewfinder and turn the focusing ring in either direction until split vertical lines of the subject image in the rangefinder are aligned or the "shimmering effect" of the microprisms disappears. If you are focusing on the matte area, the subject is in focus when the image is sharp. * You can determine the distance between the subject and the film plane by reading the distance scale on the focusing ring after you achieve 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 In focus Out of focus Microprism The OM-1 viewfinder takes in 97% of the actual picture area for added convenience when composing your pictures. Rangefinder Spot Matte Field and the orange scale indicates this distance in feet. 15 CHANGING THE LENS Lens Release Button Meter Coupling Lens Mount Ring To mount the lens, grasp the lens firmly and align the red dots on the lens flange and the camera mount ring. Turn the lens clockwise until it locks in The bayonet mount of the OLYMPUS OM-1 allows you to change lenses quickly and easily. To detach the lens, press down on the lens release button and turn the lens place. The lens release button will spring up and you will hear a positive "click" when the lens has been fully engaged. Do not apply pressure to the lens release button during the mounting procedure. This will assure proper coupling between the lens and the meter. Depth of Field Preview Button counter-clockwise. Grasp the lens firmly and remove it from the camera body. Protect your lens and camera! Always attach the front and rear lens caps when the lens is removed from the camera to prevent any possibility of damage. Never leave the camera body in direct sunlight with the lens removed and, if you plan to store the camera without the lens, the use of a body cap is recommended. Automatic Diaphragm Lever 16 INFRARED PHOTOGRAPHY/DEPTH OF FIELD SCALE/PREVIEW BUTTON The OM System lenses are provided with an infrared index mark engraved in red on the depth of field scale to the right of the reference dot. When shooting with infrared film, focus normally on your subject without the red filter on and read the subject distance on the distance scale. 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. 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 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 camera viewfinder. 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). The depth of field can be visually verified by pressing the depth of field preview button. * If you jerk the preview button while depressing the shutter button halfway down, the shutter might get released. Gently push and release the preview button to avoid accidentally releasing the shutter. 17 DEPTH OF FIELD Depth of Field Table (F1.8 & F1.4 Standard Lenses) Circle of least confusion 1/30 mm Depth of field is the area of acceptable sharpness in front of and behind the subject in focus. This depth is determined by the F stop you have selected and the distance from the subject in focus to the film plane. As you get closer to your subject or as you open your lens (e.g. from F22 to F2.8) the depth of field becomes shallower. By stopping your lens down (e.g. from F2.8 to F22) or getting farther away from your subject this depth of field or zone of acceptable sharpness can be increased. Another factor in determining depth of field is the focal length of your lens. As a rule the shorter the focal length, the greater the zone of acceptable sharpness. The longer the focal length, the shallower this zone becomes. The table above shows that when the camera-to-subject distance is 3m (10ft), the depth of field at F16 ranges from 1.93m (6ft) to 6.93m (23ft). F1.8 (1/1000 sec.) F16 (1/30 sec.) 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. NOTE: For telephotography, or slow shutter speed photography, it is recommended that you use a tripod and hold the camera steady with your hands. 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 INTERCHANGEABLE FOCUSING SCREENS (Handle with extreme care.) List of Optional Focusing Screens The OM System interchangeable fo- cusing screens provide you with the ultimate in focusing versatility. Optional screens are available to suit virtually every picture-taking situation. The focusing screens come with a special tool. To remove the focusing 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. IMPORTANT: Although the above screen: a) Detach the camera lens from the camera body (see p. 16). 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. procedure could be done with fingers, it is recommended that you use the special tool supplied. Changing focusing screens is a procedure to be handled with great care. Trying to change 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 c) Remove the screen from inside the camera by gripping the tip of the screen with the tool as shown. d) To install the screen, fit it in the repair MUST be handled by an authorized service center. Such damage is not covered by the product warranty. * See page 44 for details. (Specifications subject to change without notice.) 20 MOTOR DRIVE PHOTOGRAPHY Motor Drive has many exciting recreational, professional and scientific applications including sports photography, action portraits, copying literature, wildlife photography and timelapse photography. By automatically advancing the film and cocking the shutter, the motor tailored to the compact size of the Olympus OM-1. Extremely small and lightweight, the Motor Drive 1 mounts directly to the camera base creating one of the most compact and maneuverable motor drive systems available. Although reduced in size and weight, the OM System Motor Drive The following instructions (pp. 23-25) are for the basic motor drive system consisting of the Olympus OM-1, Motor Drive 1, and M.18V Control Grip 1 or M.15V Ni-Cd Control Pack 1. *Optimum conditions: Maximum framing rate varies with temperatures, types of films and batteries, etc. The word optimum implies such conditions in which sequence filming is made at normal temperatures at shutter speeds of 1/500 of a second and faster, using the M. 18V Control Grip 1 containing drive not only frees the photographer from the burden of manually advancing the film, but also allows him to shoot a series of pictures that might otherwise be lost through the timeconsuming manual method. The Motor Drive package is specifically Group excels in performance. The basic Motor Drive package can provide operation up to 5 frames per second in optimum conditions*, has single release capability and offers motor drive sequence applications over a wide range of shutter speeds. fresh superpower manganese batteries. Cartridges with smooth film moving must also be used. 21 OPERATION OF WINDER 1 Attaching the Winder 1 Remove the motor drive socket cap. Remove the motor drive socket cap from the camera base plate by rotating it counter-clockwise with a coin until the index dot on the cap is aligned with the index dot on the camera. To replace the cap, align the index dot on the cap with the index dot on the camera, and turn the cap clockwise with a coin until the index dot on the camera is aligned with the groove on the cap. (The removed motor drive cap can be stored in the socket cap storage positioned on the underside of the battery holder compartment.) Pull up and rotate the switch dial to the "OFF" position. Attach the Winder 1 Remove the M.6V Battery Holder 1 from inside the winder, insert four 1.5 V penlight (AA) size batteries into the battery holder, and put it back into the compartment. Insert the motor drive guide pin into the guide pin hole on the camera base plate. To assure proper connection, adjust the position of the Winder 1 until it is flush with the camera. Turn the clamping screw clockwise until the Winder 1 is securely attached to the camera base plate. The Winder 1, designed primarily for single-frame shooting, operates on four self-contained AA batteries and is extremely compact and light. The unit advances the film and cocks the Taking the pictures Pull up and rotate the switch dial to the "SINGLE" position. Press the shutter release. shutter as soon as exposure is made (wind-on time--0.3 sec.), so that the photographer can always be ready to freeze the subject at the right moments. 22 OPERATION OF BASIC MOTOR DRIVE PACKAGE Attaching the Motor Drive 1 Remove the motor drive socket cap. Attach the Motor Drive 1 in the same manner as with the Winder 1.

Align the red index line on the rear of the control grip with the red index line on the rear frame of the motor drive unit until the mounting catch is engaged. Carefully push the control grip forward until it snaps into the front of the motor drive. IMPORTANT: * Always store the socket cap in the same place to avoid loss. * After removing the motor drive from the camera, be sure to replace the socket cap to keep the camera free of dust and dirt, and to prevent the possibility of stray light entering the socket and fogging the film. * Do not remove the socket cap when *Voltage Requirement: DC 18V with "AA" (penlight) size batteries, or DC 12V--16V with external power sources of large potentiality in conjunction you do not use the motor drive. with relay cords. 23 Attaching the M. 15V Ni-Cd Control Pack 1 Prior to use, the Control Pack should be checked to insure that it has been adequately charged. If its charge is inadequate, use the M. 15V Ni-Cd Charger. Aligning the red index lines of the Motor Drive 1 and the Control Pack, engage the mount catch. Then push the Control Pack forward and upward until it snaps on the motor drive, then clamp securely. Photography with the Motor Drive Units Using the M. 18V Control Grip 1 Unlock the shutter release lock lever on the Control Grip by moving it forward and upward. You may use either the shutter release on the Control Grip 1 or the shutter release on the Motor Drive 1 to trigger the shutter. It is generally more convenient to use the shutter release on the Control Grip when the camera is held in * The lever is provided to lock the shutter release on the Control Grip for safety sake in general or when a relay cord is used.

Set the camera's synchro terminal switch (FP and X flash selector) to "X". 26 DAYLIGHT FILL-IN FLASH Manual Flash Exposure Control If your electronic flash unit has manual/auto flash exposure control, set it for manual operation. Focus on your subject to determine the camera-to-subject distance. Using the calculator dial, exposure table, or guide number formula, determine the correct F stop for proper flash exposure at the distance you found in Set the shutter speed ring to a shutter speed of 1/60 second or slower (all shutter speeds indicated in blue on the shutter speed ring). Set the F stop on the aperture ring. Auto Flash Exposure Control Follow your flash equipment instructions for the selection of F stop for automatic flash exposure control (in case of the Quick Auto 310, one of F4, F5.6, F8; ASA 100). * The TTL AUTO setting on the Quick Auto 310 is exclusively for use with the OM-2 and cannot be used with the OM-1. Manual Flash Exposure Control Determine the correct F stop for proper flash exposure by using the calculator dial or exposure table provided with your flash equipment. You may also determine the correct F stop by using the following formula: Step 2. Set this F stop with the camera aperture ring. In case of the Quick Auto 310, after setting the auto/manual switch dial to the "HI" position, read the F number corresponding with the planned flash-to-subject distance, using the distance scale provided. Turn the shutter speed ring until the meter needle centers between the overand under-exposure index marks in the camera viewfinder. If the shutter speed is 1/60 second or slower, you are ready to take the picture. If the shutter speed is faster than 1/60 second, the flash will not fire if you attempt to take the picture. Therefore, you must readjust the exposure settings 27 as follows: a. Reset the shutter speed to 1/60 second. b. Turn the aperture ring until the me- "AUTO F STOP" that corresponds with FLASHBULB PHOTOGRAPHY the F stop set on your camera and if that "AUTO F STOP" will provide automatic flash control within the distance range you found in Step 5, you may take the picture using this "AUTO F STOP" setting on your electronic flash unit. If these conditions are not met, use the procedures for Manual Flash Exposure Control. (In case of the Quick Auto 310, determine the F number and set the auto/manual switch dial to one of F4, F5.6 or F8; ASA 100). ter needle centers between the over- and under-exposure index marks in the camera viewfinder. c. Using the flash calculator dial, exposure tables, or guide number formula, determine the correct flash-to-subject distance for the F stop now set on the camera's aperture ring, d. Move to this distance from the sub- Mount the Accessory Shoe 1 to the camera and insert the shoe mount of the flash unit into the accessory shoe. * If your flash unit does not have a "hot shoe" contact, plug the flash unit's synchro cord into the synchronizing socket. Select the proper shutter speed and synchro setting from the table below according to the type of bulb being used and make these settings on the camera. Determine the correct F stop for flash exposure by using the guide num- ject and re-focus or remove the flash unit from the camera and move it only to this distance from the subject using a synchro cord extension to maintain flash synchronization with the camera. Automatic Flash Exposure Control If your electronic flash unit has manual/auto flash exposure control, set it for auto operation. Set the camera's shutter speed ring to 1/60 second. Turn the aperture ring until the meter needle centers between the over- and under-exposure index marks in the camera's viewfinder. Focus on your subject to determine the camera-to-subject distance. If your electronic flash unit has an ber formula. (See page 27.) * The guide number for any flashbulb/film combination may be found on the flashbulb packaging. Set the correct F stop with the camera's aperture ring. The table indicates proper synchronization speeds for most flash equipment. Recommended; 28 Not recommended due to bulb quality. SETTING THE SELF-TIMER LOCKING UP THE MIRROR The self-timer provides a method of taking delayed action pictures allowing you to get into your own photographs. It is also ideal for macrophotography when a cable release is not available. To set the self-timer: 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. NOTE: If you do not reset the selftimer, the timer lever will begin moving 1) Rotate the self-timer lever counterclockwise until it stops (approximately 180°). Make sure the film has been advanced properly. 2) Turn the start lever clockwise to the vertical position to activate the immediately after advancing the film and the shutter will be released earlier than expected. You may set the self-timer lever either before or after advancing the film. Even after setting the lever, you can release the shutter by pressing the To minimize camera vibration in closeups, reproduction work, macrophotography and photomicrography, you can lock the instant return mirror in the up position to eliminate mirror shock. This is also handy in rapid sequence shooting. To lock up the mirror, compose and focus on your subject and then turn the mirror lockup lever counter-clockwise until it stops (approximately 90°). After self-timer lever. The shutter will then be released in approximately 12 seconds. You can adjust the delay time between four and twelve seconds by adjusting the lever as shown above. If the film has not been advanced properly, the timer lever will stop halfway and the shutter will not fire. To re-activate the timer, move the start shooting, always return the lock-up lever to its original position.
