Description

The ARRI cforce mini RF is a compact lens motor with a built-in white-coded radio. It removes the need for a separate receiver on the camera, so small rigs stay tidy and light. As a result, it suits gimbal, drone, Steadicam and handheld work on many cameras.

Radio and hand units

The motor pairs with up to three hand units, so separate operators can split focus, iris and zoom. It offers 14 radio channels, which are set using two buttons and a small display. It also provides full lens data with the WCU-4 hand unit. However, this white radio can’t share a network with legacy yellow radio or cmotion red radio.

Expanding the system

Two additional cforce motors can connect over LBUS for full three-axis control. In addition, the CAM connector supplies power and run/stop control for ARRI, RED, Sony, Canon and Blackmagic cameras. These connections need the right cable, so tell us your camera when booking.

Before you book

We supply this motor with lens gear, cables and other accessories as per client request. For that reason, confirm your lens, rod size and hand unit with us ahead of the shoot. We can then advise which accessories your setup needs.
