Our Tilta Nucleus M Set contains everything you need for remote focus control: 2 motors with power supply cables, 2 handles that also have all controls for direct operation by the cameraman, 1x triple channel radio module for control of all motors by one operator. The set comes complete with 8x 18650 batteries and charger. For operation, you need either 2 batteries in a handle, or if you want to use the remote, you need 2 additional batteries - so 4 in total. So you always have a complete set as a backup. Optionally the motors can also be powered by the Camera or a V-mount battery via a D-Tap cable, which is interesting when using the system on a gimbal. For the mounting of the handles, there are 2 Adapters on Arri rosette and 2 mountings for 25mm/30mm tubes like on a DJI gimbal. Also in the set is an attachment to attach the handles to 15 or 19mm rigs.
