Olympus OM Motor Drive Group The attraction of the motor drive is its ability to capture fleeting phenomena which exceed the capabilities of human response. Tailored perfectly to match the OM camera body, each unit of the Motor Drive Group has been reduced in size to enhance its maneuverability and ease of operation.


The basic motor drive package (Motor Drive 1 + M. 18V Control Grip 1, or Motor Drive 1 + M. 15V Ni-Cd Control Pack 1) features an amazingly compact and lightweight design, permitting handheld photography even with a 300mm telephoto lens, for shooting sports and news events or other action subjects.

Motor Drive 1 | Motor Drive 2 | Winder 1 | Winder 2

The Winder 2 is designed for the ultimate compactness operating on self-contained batteries to perform single or sequential shooting. The 250 Film Back 1, which holds enough bulk film to give 250 exposures, attaches to the OM camera body without cords. The M. AC Control Box is useful for copy work, time-lapse and other photography by transforming household current to DC for motor drive use via a relay cord.


The many uses of the units of the Motor Drive Group in conjunction with other units of the Macrophoto, Photomicro and Flash Photo Groups permit even a greater range of photographic possibilities with the motor drive than originally imagined.

" ... OLYMPUS 250 FILM BACK1 WITH 35-POF This is an Olympus 250 exposure back with the 35-POF computer attachment made by Miletus Assoc., New Mexico. I think this was made for record keeping and used by the USN. It will work as a long roll back on any OM1 or 2 and maybe with the OM3 & 4 as well. At any rate it's a cool item and if your into OM cameras this might be a great addition to your collection. It would work well for large group photos or sporting advents...." - Michael -
