The ZMU-3, a new member of the ARRI Wireless Remote System, is shaped like a classic handgrip zoom controller and has the classic zoom knob that assistants' thumbs all over the world are familiar with.

Contrary to its classic exterior, under the hood it is equipped with the latest technology. Zoom speed can be precisely adjusted and zoom limits can be set. A large bar graph shows the zoom ring position, the zoom speed and various status messages, and a ZAP button allows for a quick focus check. A switch changes the running direction of the attached lens motor. Of course the RUN switch can start film cameras, but the ZMU-3 can also start/stop some high end video camcorders and control the zoom motor on various video lenses.

If only zoom is required, the ZMU-3 can be connected with a cable directly to an ARRI CLM-1 or CLM-2 lens motor and to the camera. If focus and/or iris are also to be used, the ZMU-3 can become part of the cabled ARRI Lens Control System (LCS) or of the ARRI Wireless Remote System (WRS) by being connected to a Universal Motor Controller UMC-1, Universal Motor Controller UMC-3, Lens Data Box or FEM-2.

For wireless use, the ZMU-3 becomes part of the ARRI Wireless Remote System. Via the Wireless Zoom Bracket WZB-3 it attaches to the Wireless Main Unit WMU-3. The special shape of this bracket allows the assistant to position the ZMU-3 in relation to the WMU-3 to suit his/her personal preference.

The ZMU-3 finally allows an ARRI LCS and WRS compatible zoom controller to be attached to the tripod handle. This can be done either with any of the existing handle adapters, or with the rosette on the right side of the ZMU-3 (M6 thread).

With its classic shape and modern electronics, the ZMU-3 is a welcome addition to the ARRI Wireless Remote System.
