The Nikon MF-2 provides the largest bulk film transport capacity available for the Nikon F2 series. Its film chambers and optional bulk film cassettes (MZ-2) accept standard 100-foot bulk film loads for up to 750 exposures at a time.
Film advance itself is done by the MF-2’s own built-in motor. When the MF-2 is attached to an MD-2-equiped camera it “blanks out” all the speed and operation controls (including the S/C [single and continuous] knob of the MD-2 motor drive unit. Speed selection of up to 4 frames per second is then made via the MF-2’s rear control panel, regardless of the motor drive’s firing rate.
Power socket/remote terminal: Operating power is supplied by the Nikon AC/DC Converter MA-2/MA-4.
