Wireless Zoom Unit 3 (WZU-3)
Wireless Zoom Unit 3 (WZU-3)
The WZU-3 is used to control zoom. Zoom speed can be adjusted and zoom limits can
be easily set. The WZU-3 is similar to the WZU-1 except that it is lighter than the WZU-
1 and the position of zoom knob and the LENS limit controls are reversed. The reversed
zoom knob is in the perfect ergonomic position for the assistant’s thumb when the WZU-3
is used on WMU-3, WHA-2 or WHA-3.
Compatibility: For wireless operation, the WZU-3 was especially intended for use with
the WMU-3, although it can be used with other main units. For wired operation with
ARRICAM, 435 Xtreme or 416 Plus, WZU-3 can be used with Wired Handgrip Attach-
ments WHA-2 or WHA-3. The WZU-3 can be placed between the Wireless Focus Unit
and a Wireless Main Unit or Wired Handgrip Attachment, so focus, iris and zoom controls
are together on one small and lightweight controller. The WZU-3 should not be placed
between LDD-FP or WRC-1 and a Wireless Main Unit.

With this bracket the WMU-3 can accept two hand controllers simultaneously, for example
WFU and LDD-FP, or WFU and WRC-1.

operate the WRC-1 and the Lens Data Display for Focus Puller (LDD-FP) on the same
Wireless Main Unit. For wireless operation of WRC-1 and LDD-FP at the same time, two
Wireless Main Units must be used. The same is true for two WRC-1 and LDD-FP units.
