Arri announces cforce mini RF Lens motor

The ARRI cforce mini RF is an intelligent lens motor with an integrated radio module, which eliminates the need for an additional camera-mounted receiver unit.

 Key Features

  • Integrated white-coded radio module eliminates the need for an additional receiver box
  • 14 radio channels
  • Lens data support for focus mapping and lens data display on WCU-4 hand unit
  • Daisy-chainable with additional classic cforce motors and LBUS devices
  • Interface for run/stop control with ARRI and third party cameras


Based on the widely-adapted cforce mini motor, the cforce includes the latest iteration of ARRI’s white-coded radio module with improved interference resistance and six additional radio channels compatible with the soon to be released WCU-4 SUP 3.1. It comes with the outdoor antenna already used on the UMC-4 motor controller.

The ARRI cforce mini RF can pair with up to three hand units for split focus, iris and zoom operation and provides full lens data for focus mapping and lens data display with the WCU-4 hand unit. Using the LBUS interface, the system can be expanded with two additional cforce motors, while the new CAM connector provides a versatile interface for power supply and run/stop control with ARRI, and 3rd party cameras (including Red, Sony, Canon, and Blackmagic).
