Extremely compact and handy battery-powered motor drive. The LEICA MOTOR M is attached to the camera in place of the baseplate and it couples to the camera mechanically. Provides a choice of 1.5 or 3 frames per second. Specially designed motor with a particularly quiet friction drive, the sound is reduced even further at the 1.5 fps exposure frequency. Runs on two 3 V lithium batteries Type 123 A, housed in the ergonomically designed grip.
