Leica R8 Remote Control Description The electronic control unit for the LEICA R8 - LEICA REMOTE-CONTROL-R8 - enables programmed exposure series as well as remote control of the camera when used with the LEICA MOTOR-WINDER-R8 and the LEICA MOTOR-DRIVE-R8. It allows the intervals between the individual exposures as well as the number of exposures themselves to be determined freely within a wide range.
