Fujinon SRD-92B Zoom Rate Demand Unit for LA Series and eXceed Series Lenses

The SRD-92B is the zoom rate demand in Fujinon's portable lens control system: a rear grip with a thumb rocker that gives proportional zoom speed instead of the fixed rate of a mechanical control, plus RET and VTR switching under the same hand. It clamps to the camera's control rod and drives the lens servo through a six-pin connection, and Fujinon offers an ECF-126 conversion cable when the lens presents a 12-pin socket.

It is the zoom half of three published Fujinon configurations: the MS-X1 kit on LA Series lenses, and the MS-01 semi-servo and SS-01 full-servo kits on eXceed Series lenses. When the demand needs to sit away from the camera, Fujinon lists ECC extension cables in one, five and ten metre lengths.
