The Nucleus-M is a revolutionary follow focus system. Designed to be lightweight and efficient, each brushless motor is made completely wireless via built-in MDR. Trying to hit the record button can be frustrating when protected by camera cage armor, on a gimbal, when shoulder mounted, or when the camera is just out of reach. Use this cable to easily Run/Stop the Arri Alexa Mini wirelessly from the Nucleus-M Hand Grips or FIZ unit when the run/stop cable is connected via a Nucleus-M motor’s 7 pin. Run/Stop can also be triggered through a hardwired connection from the Nucleus-M Hand Grips, FIZ unit, but NOT compatible with the Tilta Wooden Handle 1.0 or 2.0.
