The Tilta Nucleus-M Wireless Follow Focus system has two wireless motors, an FIZ hand unit and two wireless handles. One to control focus, and one for the iris or the zoom. The wireless motors each have a standard 0.8 MOD drive gear and two 7-pin connectors, which allows you to freely switch each motor. You can power the motors through series connection using the 7-pin cables. Each motor has a 19 mm bar clamp with 19-15mm reduction ring. The FIZ hand unit controls the focus, iris and zoom. The wireless handles are fitted with adapters to mount the handles to ARRI-compatible rosettes or on bars with a diamter of 25/30mm, like on gimbals.
