ABSTRACT:
A motor drive unit adapted for use with a camera having a motorized shutter speed adjusting device. When a continuous series of frame exposures are to be made at a predetermined frame frequency, the set value of shutter time in the camera is made to be compared with the longest possible shutter time dependent upon that frame frequency by a comparator provided in the motor drive unit. When the actual shutter time value exceeds the longest possible one, the motorized shutter speed adjusting device is actuated, causing the shutter time value to change itself to the longest possible value.
