Olympus Motor Drive 2 (Instruction Manual)

Olympus Motor Drive 2 is essentially an upgrade to the version 1. But since development of SLR has leapfrogged over the years, newer electronic was designed and made camera with more capabilities; the aged Motor Drive 1, although brilliant in its own right, but could not keep pace with the rapid development and when Olympus started to offer its newer range of many exciting SLRs during the early eighties, the time calls for a new generation Motor drive to replace the older version, with fair amount of backward compatibility with all those older OM SLRs.

The new drive, a brilliantly conceived, modern looking new motor drive unit that achieved several firsts of its kind, but amazingly, all these were not being compromised the remarkable compactness and light weight which is a typical hallmark of OM system, while at the same time, maintaining a fast top speed of five frames per second, even without the necessity of mirror lock-up. Other refinement made are, it minimizes and improved shock with a fabulously smooth drive mechanism that use a twin motors that rotate in opposite directions. In addition, with appropriate OM SLR models attached, it also provides motor driven film rewind. Credit: SB Teoh Dr, for rectifying a mistake made on this page.

The new Motor Drive uses another exclusive feature, a graphic LCD display controlled by a built-in computer. The computer also advances new film automatically to the start "Frame 1" position *, and stops automatically when the counter reaches "0:' etc. This new OM Motor Drive also allows you to use any automatic or manual shutter speed freely. As with the OM3, and OM4 series camera models, the drive uses a aluminum alloy which coated with another layer of industrial grade paint for better corrosive resistance and it has incorporated a shower resistant scaling design with O-ring protecting critical entries to moisture and dust penetrations. Overall, I would still considered it is a worthy upgrade of earlier version, a truly first class Motor Drive if it combines with appropriate OM SLRs to unleash its full potential.

M. 18V Control Grip 2 Similar function as with the earlier version. It is a pistol grip type power/control unit that's quite popular for action motor drive but looks odd by modern standard. The Grip 2 snaps onto the motor drive unit instantly, and is kept in place with a foolproof double lock system. The trigger release can be locked to prevent accidental exposures. The built-in Mode selector is a rotating dial type with "SINGLE", "SEQUENCE" and "OFF" click stop positions. Solid-state circuit for automatic film wind stop after last exposure. The shutter release is a large trigger-type with lock lever. The shutter release on the motor drive, that can be used alternatively, is not influenced by the position of the Shutter Release Lock Lever. Grip 2 uses 12 "AA" penlight (Alkaline or Manganese, 18V; Ni-Cd batteries: 15V.) batteries for a power source. They are fitted in the M.18V Battery Holder 1, which slides quickly into the body of the Grip.

M.18V Battery Holder 1 This handy unit slips instantly into the M18V Control Grip 1/2. It contains 12 1.5V Manganese or Alkaline; or 12 1.25V Ni-Cd penlight batteries. Spare M.18V Battery Holder units are available separately.

M.15V Ni-Cd Control Pack 1 A flat-type rechargeable power unit that attaches to the Motor Drive 1(2) unit in the same way as the M.18V Control Grip 1(2) to give the smallest, lightest motor drive assembly equipped with special built-in Ni-Cd cells. M.15 V Ni-Cd Control Pack 1 and M.15 V Ni-Cd Control Pack 2. The assembly has the same performance characteristics as with the Control Grip 1(2). Version two operates similarly with no significant operational improvement except cosmetic changes, mainly at the attachment knob it is made of metal on Pack 1 and of plastic on Pack 2. In operation, it is clamped directly to the Motor Drive, or via a Relay Cord.



Charging time: 4 - 5 hours for full charge. Capacity: Approx. 40 rolls of 36 exposure film Mode Selector: SINGLE, SEQUENCE and OFF, lift-and rotate dial setting. Battery checking: 3 level checker lamp (LED) Size: 129 x 67 x 35mm (5.08 x 2.64 x 1.38in.) Weight: 260g (9.2oz.)
Battery: Built-in Ni-Cd cells.

M. 15V Ni-Cd Control Pack 2 This flat type rechargeable power unit screws onto the base of the Motor Drive 2, or can also be attached by a relay cord when more convenient. In addition to housing the Ni-Cd power source, it provides a selector dial with Single or Sequence shooting and Off positions, plus an extra shutter release button on the rear, especially useful for vertically framed shots. The compact size and excellent balance make this the power unit of choice for general purpose photography. The Control Pack 2 can also be used with the original Motor Drive 1. There is a large, easy-to-operate mode selector dial (Sequence-Off-Single) and a solid-state circuit to prevent wind-on during shutter opening and after last exposure. A checker lamp is also provided and indicates a 3-level battery condition (on-blink-off). You will needd the M. 15V Ni-Cd Charger 1 or 2 for the Control Pack (see below). The relay Cords 1.2m and 10m can be used for remote-control motor drive photography. In extremely low temperatures, battery power drops and the checker lamp may blink after less than normal number of film cartridges used. To prevent this, connect the unit to the Motor Drive via relay Cord 1.2m and put it inside a coat pocket. Internal Ni-Cd cells are built-in and cannot be removed from the unit.
