The ARRI WCU-4 Wireless Follow Focus Set includes a 3-axis handheld controller featuring an integrated lens display.
The hand unit controls camera functions, focus, iris, and/or zoom from a distance, such as when shooting handheld or using a stabilizer, gimbal or crane.
The WCU-4 is compatible with the ARRI ALEXA Mini, ALEXA Plus, and Studio cameras, and with ARRI UMC-4, SMC-1, EMC-1, and AMC-1 motor controllers. Camera functions are controllable for ARRI ALEXA Mini, Plus and Studio, and ARRI AMIRA when used with the UMC-4 motor controller.
Vibrating markers and a backlit display make it easy to use the WCU-4 in low light levels. Multiple 3/8″-16, 1/4″-20, and M4 mounting points enable you to attach the controller to a rig when convenient.
The latest addition to the cforce motor family “cforce plus” combines the convenience of cforce mini’s revolutionary function button with a brand new motor. The recognizable twin LBUS connectors allow up to 3 cforce motors to be daisy-chained in any combination from any compatible cmotion or ARRI LCS while the new standard split clamp offers superior mounting flexibility.
All cforce motors are compatible with cmotion’s compact LCS, cvolution LCS, pan-bar zoom, knob solo, ENG adapters plus ARRI’s ALEXA Mini, UMC-4 and AMC-1.
