ARRI | Wireless Zoom Extension Unit WZE - 3 | ELECTRONIC CONTROL SYSTEM

ELECTRONIC CONTROL SYSTEM
Any camera. Any lens.
Flexible control for any setup
ARRI’s Electronic Control System is a sophisticated toolset for precise wireless
remote control of any camera and any lens; it also provides valuable metadata
about exactly what the lens is doing at any given moment.
All tools within the modular, future-proof system can be freely combined to
provide powerful, scalable solutions for any application. Ergonomic, feature-rich
hand units ease the work of the focus puller, while compact, intelligent motor
controllers optimize camera setups.
ARRI has assembled the most complete professional system on the market,
ready for any challenge on set.

The Universal Motor Controller UMC-4 is the most advanced motor controller
available today. It connects with up to three different hand units to drive focus,
iris and zoom motors on any lens. The integrated ARRI Lens Data System® (LDS®)
provides real-time information about focus, iris and zoom settings, enabling
lens mapping to pre-marked focus rings, depth-of-field display on the Wireless

How does the Lens Data System work?
Lens data generation has two basic requirements: encoders that determine the current setting of a lens axis,
and a lens table that interprets these raw encoder values. ARRI offers two configurations:
Option 1. LDS lens and LDS-mount camera
Option 2. External lens encoders and the Lens Data Archive
Each LDS lens can detect the position of its lens rings and store its
ARRI’s controlled lens motors and the Lens Data Encoder LDE-1 deliver raw data about

Autonomy and freedom
The Universal Motor Controller UMC-4 allows ARRI’s Electronic Control System to function as an
autonomous, camera-independent system. With it, up to three different hand units can be used to
control focus, iris and zoom motors on any lens, attached to any camera. Lens data can be displayed
on the WCU-4 hand unit and used for focus tracking, while also being stored with timecode for VFX
applications in post. Multiple interfaces facilitate compatibility with peripheral equipment.
17
Diverse options
The three available controlled lens motors offer a range of torque, speed and size choices
for 19 mm, 15 mm or 5/8" support bars. The compact CLM-2 is a proven workhorse for
everyday applications; the CLM-3 is strong and fast for heavy lenses or difficult conditions;
and the CLM-4 is exceptionally smooth and quiet, with flexible mounting options.
