ARRI Electronic Control System To Include More Camera and Lens Compatibility


Last Updated: April 4, 2014 5:43 pm GMT
(Las Vegas, Nevada--April 4, 2014) ARRI’s Electronic Control System is a sophisticated toolset for remote camera and lens control. It includes the award-winning WCU-4 wireless hand unit, which displays extensive lens data when used with ALEXA Plus and Studio cameras, as well as its smaller companion, the SXU-1 single axis hand unit controlling either focus, iris, or zoom. A range of new motor controllers gives the Electronic Control System complete operational autonomy, allowing the WCU-4 and other system elements to be used with all types of cameras, including the new ARRI AMIRA cameras and other third-party cameras.

Universal Motor Controller UMC-4
The new Universal Motor Controller UMC-4 is an advanced 3-axis motor controller that offers functions previously only available with ALEXA Plus and Studio cameras. By incorporating ARRI’s LDS Lens Data Archive, the UMC-4 goes beyond mere camera and lens control to offer the added value of lens data that is useful both on set and in post. Lens data provides the current setting for focus, iris and zoom. This information enables lens mapping to pre-marked focus rings and depth-of field display on the WCU-4 wireless hand unit. It also enables the UMC-4 to do focus tracking by setting the focus motor to continuously follow a subject in the frame by using an ultrasonic measuring device. For VFX tasks in post, the UMC-4 records frame-accurate lens data with time-code to help match the virtual lens to the recorded image. The UMC-4 includes multiple serial interfaces (RS232/422/485) that can be configured for peripheral equipment such as ARRI’s UDM-1 distance measurer, or that can stream real-time lens data on set. Optional connector modules directly interface with focus and zoom demands from Fujifilm and Canon. An Ethernet connector integrates the UMC-4 with standard IT equipment, allowing convenient lens table programing and Ethernet-based system control. The intuitive user interface makes the UMC-4 easy to use, while its high-quality outdoor antenna offers improved durability and reliable radio connectivity.

Single Motor Controller SMC-1
The Single Motor Controller SMC-1 is a compact 1-axis motor controller designed for weight and size-critical setups such as Steadicam or camera drones. It drives a single CLM motor and is the perfect counterpart for the SXU-1 single-axis hand unit.

ENG Motor Controller EMC-1
The ENG Motor Controller EMC-1 was specifically developed for use with ENG-type lenses such as the Fujinon Cabrio Zooms. The EMC-1 controls the integrated focus, iris, and zoom motors of such ENG lenses and provides lens data for display on the WCU-4 hand unit.

All Electronic Control System components are built to withstand hard, prolonged use on set. Every single tool in the Electronic Control System range is backed by ARRI’s worldwide network of official service centers, so support from trained technicians is available 24 hours, five days a week. Software updates can be easily performed via SD card, ensuring a future-proof system that can adapt as new functions evolve.
