The Zoom Main Unit ZMU-3A is a handgrip zoom controller that can be mounted on tripod pan arms while being connected to camera and motor. It includes a force sensitive zoom knob that assistants&8216; thumbs all over the world are familiar with.
Zoom speed can be precisely adjusted and zoom limits can be set. A large bar graph shows zoom position, zoom speed and various status messages, and a ZAP button allows for a quick zoom-in for focus check. A switch changes the running direction of the attached lens motor. The RUN switch starts recoding on film and digital cameras.
Tethered or Wireless Operation
ZMU-3A can be connected directly to an ARRI CLM-2, CLM-3 or CLM-4 lens motor and power source. Alternatively, it can be connected with the UMC-4 motor controller or any ALEXA camera that includes the Plus Module. The optional Wireless Zoom Extension WZE-3 allows wireless operation of the ZMU-3A. In any case, the ZMU-3A can be used in parallel with WCU-4.
