The Preston FI+Z Lens and Camera Control 2 channel system can control both lens functions (focus and iris) as well as camera functions (speed, shutter angle, and VTR). The FI+Z system consists of the Hand Unit HU3, Motor Driver MDR-4, a set of DM2 Digital Motors, and a variety of optional controls including wireless Focus/Iris, Zoom and F/X units.
Preston HU3 Hand Unit
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. It integrates its 30 channel 2.4GHz wireless link into a new splash-resistant housing. Weather sealed tactile switches are used throughout. The integrated microwave antenna is protected from impact. The iris slider uses a unique non contact technology to eliminate the opening required for a conventional sliding seal. The HU3 allows for programming camera speed and shutter angle. Power is provided by widely available FM-50 Li-Ion batteries.
The Preston MDR-4 is a lightweight dual-channel motor driver which works with the Preston HU3 Hand Unit or with the Preston Focus/Iris (F/I) Hand Unit and is perfect for any shoot which requires hand held rigs, gimbal, Steadicam, or even drones.
The MDR-4 offers a built-in antenna, two sets of 30 channels, plus a reset button. It also provides a serial connector for Cine Tape, and an analog connector for Canon and Fujinon video-style lens controls or for Microforce/broadcast zoom controls.
Preston DM2 Motor
The DM2 delivers a unique balance of power, weight, and ruggedness. The motors have ceramic-coated magnesium housings for minimum weight and metal gears coated with diamond-like-carbon for long life under high torque conditions
Units connected via the wireless microwave link or cable, and controls up to two digital motors as well as camera functions for both film and video cameras. In addition, it allows wireless control of both the camera frame rate and shutter angle when used in conjunction with the F/X box.
