Classic SLRs Series :
Flash photography with T32/T20 automatic Electronic Flash Units. 1. Set the ASA film speed on the calculator panel 2. Mount the T32 (or T20) on the Accessory Shoe 4 (More info available on other Issues section).
3. Set the shutter speed ring to 1/60 sec. or slower (the shutter speed indicated in blue on the shutter speed ring). 4. Set the desired f/stop on the flash unit. Set the aperture ring to this f /stop. With T32: F4, F5.6 or F8 on automatic flash operation (ASA 100). With T20: F4 or F8 (ASA 100).
5. Switch on the T32 (or T20). When a red lamp lights in the viewfinder you are ready to fire. 6. The lamp flickers to indicate that correct exposure has been made. If it does not flicker, the flash-to-subject distance is beyond the auto range: get closer to the subject.
If the LED viewfinder lamp does not blink repeatedly after firing: This indicates the flash unit has reach its maximum output to ensure furthest reach of distance or it may interpret as possibility of underexposure, in such case -+ get closer to the subject.
Flash Photography with an portable Electronic Flash Unit OTHER THAN dedicated Olympus flash of T-32 or T-20 (Third Party Options):
1. Attach the Accessory Shoe 4 to the OM-1(n) or you can still use older Accessory Shoe 1 or "Fix" type shoe. With the OM-1n, flash ready light will be available when used in conjunction with a dedicated flash/Accessory Shoe 4 because it automatic X-sync with Shoe 4, regardless of the position of the FP/X switch on the camera body.
2. Mount the electronic flash on the accessory shoe. If your electronic flash unit does not have a direct contact "hot shoe", connect its synchronizing cable to the camera flash socket.
3. Set the synchro terminal to "X" by aligning the red dot on the FP and X selector with the "X" indication alongside the flash socket. Note: Mounting the electronic flash unit on the accessory shoe automatically completes the "X" synchro circuit. However, there are some flash units which do not fire unless the selector is set to " X ".
4. Set the ASA film speed on the flash unit.
5. Set the shutter speed ring to 1 /60 sec. or slower.
6. Set the flash unit to the automatic or manual setting.
7. Set the desired F stop on the flash unit (in the case of auto mode), and then set the aperture ring to this F stop. In the case of manual mode, F stop can be determined by using the following formula:During those early days when the OM-2 was introduced, one of the biggest attraction of the OM system is its TTL OTF flash exposure control system which can only be found on the OM-2(n) bodies. The OM-1 can only use manual or autoflash photography. The above equation presented is for manual flash exposure calculation. Auto flash works by means of having metering cell that housed on the flash unit reading flash output reflecting back from the subject rather than from OM-2(n)'s camera method of reading light from the film plane inside the mirror box. In theory, virtually all AUTO flash unit can work on a OM-1 (Believe or not, even Nikon, Canon made auto-enabled flash will work equally well...). The trick is the center main contact (Hot shoe contact) on the accessory shoe where most flash would have had to sync for proper synchronization for a flash exposure to take place. For any auto/manual flash that DOES NOT has a hot shoe contact on the flash mounting foot, you still can make use of the PC terminal to enable cable or cord connection.
Daylight Synchronization ( Photography) The flash unit may be used as a fill-in light source to illuminate a subject in shadows caused by the sun. However, since none of the manual focus OM bodies has shutter speed higher than 1/125 sec for proper flash synchronization, it is still fall short of a perfect solution for such application especially when the surrounding is too bright for syncro-sunlight photography.
Note: The OM-3Ti and OM-4Ti eventually provide a solution to the main drawback of the OM flash system with the introduction of a innovative method of FP sync with the use of a T280 flash which will permit high speed flash synchronization up to 1/2000 sec !
But most of other OM SLR bodies still provide a relatively slow 1/60 sec flash synchronization which generally fell short from modern standard. Anyway, the continuous OTF metering for automatic OM bodies for both ambiance and flash exposure is till too good to complain about and could well compensated for such shortfall.
1. Manual flash exposure control (1) Read the f-stop corresponding with the planned flash-to-subject distance shown in the calculator dial. Set the aperture ring to this f-stop. (2) Aim the subject and turn the shutter speed ring until the meter needle centers between the over- and underexposure index marks in the viewfinder. If the shutter speed is 1/60 sec. or slower, you are ready to take the picture. (3) If the shutter speed is 1/125 sec. or faster, move closer to the subject and repeat the procedure (1) and (2) to obtain the proper shutter speed of 1/60 sec. or slower. 2. Automatic flash exposure control Daylight synchronization on automatic mode is possible, but limited to a considerable extent by the ambient light and subject conditions. Therefore, manual flash operation is recommended. Flash with intentional slow sync would create dramtic visual effect to portray a sense of movement, anyway, just use it creatively.
Flash Bulb Photography Once popular during the '60 and mid '70, but rarely seen many people using them nowadays, but both OM-1 and OM-2 series models have clearly defined flash bulb settings on the cameras.
1. Plug the synchronizing cable leading from the flash unit into the camera flash socket, and then attach the flash unit to the camera. 2. Select the proper synchro setting from the table below according to the type of bulb being used, and align the red dot on the X and FP flash selector with the "X" or "FP" indication alongside the flash socket. 3. Select the proper shutter speed from the table below, and set the shutter speed ring accordingly. 4. Determine the correct F stop for flash exposure by using the calculator dial, exposure chart or guide number formula. Set the aperture ring to this f-stop. Caution: With the clip-on type "FP" class flash unit, the synchronizing cable must be used to connect the unit and the camera. • The table indicates proper synchronization speeds for most flash equipment.

Motor Drive Photography By automatically advancing the film and cocking the shutter, the motor drive allows the photographer to achieve rapid-fire shooting. The Motor Drive package consisting of the OM-1(n), Motor Drive 1, 2, and M. 18V Control Grip 1 (or M. 15V Ni-Cd Control Pack 1) is extremely compact and maneuverable. The Winder 2 is designed for the ultimate compactness to perform single frame as well as sequential shooting.
Instruction Manual for OM Motor Drive 1 | Motor Drive 2 | Winder 1 | Winder 2
An automatic film advance device such as Motor Drive or Winder can help you be more responsive to action or happenings around you. There are more reasons for camera to have a motor drive attached to its body other than just confining within the world of capturing action. With the shutter always ready for the next shot, you'll have every chance to pin down un-repeatable moments of truth as they come. You can also try motor-driven multiple exposures for special effects or take sequential shots of a action game. Most of the time, camera manufacturers make use of the motor drive or winder to extend camera's capabilities such as remote, time-lapsed or unmanned photography. As with the Databack, depends on camera and accessories, within OM system it has quite a few combinations with new/old models or versions of camera/Motor Drives/Winders. Although it sounds different but Motor Drive and Winder are essentially providing similar basic function i.e. winding film automatically. But a motor drive in general will wind film with higher speed rate than a Winder (Generally people use frames-per-second or generally referred as 'fps' to determine their performance). OM motor drive(s) has a first rated performance of enabling high speed film advance rate of 5 fps which put the Motor Drive 1 and the upgrade of Motor Drive 2 among forerunner among all manufacturers in terms of performance. On the other hand, OM system also provides an aleternative form of more economical entry but at the expense of slower film advancing rate of single frame advance in Winder 1 or 2.5 fps sequential rate in Winder 2. The Winder 2 wasis more responsive in actual operation automatically advance to the next frame and you need not have to release the finger from the shutter release button . Motor Drive 2 has many added features to enhance its reliability and performance. However, some useful feature such as Auto film rewind does not operate when used with camera bodies such as OM-1(n) nor with the OM-2(n). Auto film rewind feature on Motor Drive 2 only works with OM-3(Ti) and OM-4(Ti). Among other refinements, Motor Drive 2 is more reliable and it has a LCD display which shows film loading, film rewind(not appllicable on OM1), and film removal sequences, along with a frame counter that counts down from the preset number of frames to zero, where the drive automatically stops.
• Attaching the Motor Drive 1
1. Remove the motor drive socket cap from the camera base plate.
2. Insert the motor drive guide pin into the guide pin hole on the camera base plate. Turn the clamping screw clockwise until the Motor Drive 1 is securely attached to the camera base plate.
• Attaching the M. 18V Control Grip 1 1. Remove the M. 18V Battery Holder 1, insert twelve 1.5 V penlight (AA) size batteries into the battery holder into the Control Grip. 2. Align the red index line, and push the control grip forward until it snaps into the front of the motor drive. Note: At flat-type rechargeable power source, M. 15 V Ni-Cd Control Pack 1, is also available.
* Photography with the Motor Drive Units Using the M. 18V Control Grip 1 1. Unlock the shutter release lock lever on the Control Grip. 2. Turn the mode selector to either "SINGLE" or "SEQUENCE". 3. Release the shutter. Note: At "SINGLE" setting, exposure is possible at all shutter speeds from 1 sec. to 1/1000 sec. At "SEQUENCE" exposure is possible at all shutter speeds except B. and 1 sec.
Care & Maintenance General: *Dust and moisture are harmful agents affecting your camera. Remove the camera from the case and store it in a dry, well-ventilated place making sure the shutter and self -timer are free from tension. Do not store the camera near moth balls or similar volatile chemical materials to avoid the possibility of damage to metal surfaces. * When storing the camera for a long period of time, remove the battery. Protect against excess moisture by using packs of silicagel or other desiccant in the storage area. Wipe battery surfaces with a dry cotton cloth before reinserting into the camera. * Avoid dropping or hitting the camera. * Never store the camera where temperatures exceed 50° C (122° F) for extended time. When you use the camera in temperatures under -20° C (-40F), it may sometimes fail to operate properly. To avoid this, warm the camera before use. * After use near the ocean, wipe the camera surfaces clean with a soft cloth; never leave salt on the camera. * Protect the camera from infiltration of water drops and splashes. * Avoid excessive tightening when mounting on a tripod. * Never expose the camera to direct sunlight. Avoid areas exposed to corrosive chemicals, radios, TV sets, or magnets. • Do not press the shutter release button at random. * Do not touch any part that moves at high speed such as the shutter, instant return mirror, diaphragm, etc. • Avoid touching the surfaces of the lens. Clean only with an air blower, antistatic brush, or wipe it lightly with a camel hair brush or lens tissue. In EXTREME cases, use a clean, soft cotton cloth moistened with denatured alcohol. NEVER rub the lens surfaces with your finger, clothing, or other abrasive material.
* Caution in Low-light Exposure Metering The meter's exposure range is EV 2-17 (ASA 100, with the 50mm. F1.4 lens). The list below summarizes the lowest measurable limit in dealing with extreme low light conditions. Below this limit or with the meter switch at OFF, when the aperture ring or shutter speed ring is rotated, the needle sometimes swings but the meter is not functioning.
ASA 100, with 50mm f1.8 1/2 sec at f1.8
ASA 100, with 50mm f1.4 1/2 sec at f1.4
ASA 100, with 50mm f1.2 1/2 sec at f1.2
