Drive 1
| Summary | Main Characteristics | Notes - Related Units |
| Basic motor drive unit that forms -together with Motor Drive 2- the core of the group. Fixed directly to the camera baseplate, it functions integrally with the OM camera body to perform high-speed sequence/single frame advance motor drive photography, operating on various power supplies. | Incomparably compact and lightweight. A maximum sequential filming speed of 5 frames per second without mirror lock-up is the fastest among motor drives generally available on the market. In single mode, pressing of the shutter release button completes film wind-on following exposure, thus setting the camera ready for the next shot - a big advantage in assuring split-second readiness over its counterparts that require the finger to be taken off the button to initiate wind-on. Solid-state circuit prevents wind-on during shutter opening and after last exposure. |
Power units for Motor Drive 1 - M. 18V Control Grip 1 or 2, M. 15V Ni-Cd
Control Pack 1 or 2 and M. AC Control Box. Early OM-1 models not prepared for motor drive use can be modified for a nominal charge at authorized Olympus service centers. |
