The FI+Z system controls the complete array of both lens and camera functions. It consists of the Hand Unit HU3, one or more Motor Drivers (for 3D), a set of Digital Motors, a Micro Force zoom control, and a variety of optional controls including wireless Focus/Iris, Zoom, and F/X units.
The HU3 gives focus pullers not only a robust and reliable unit but one whose controls equip the focus puller to smoothly translate the changing actors’ positions on set to a precise movement of the focus knob.
