I. Introduction
A. System. The FI+Z system controls the complete array of lens and camera functions.
It consists of the Hand Unit HU3, one or more Motor Drivers, a set of Digital Motors, a
Micro Force zoom control, and a variety of optional controls including wireless Focus/Iris,
Zoom, and the Light Ranger 2 focus assist.
B. The HU3 gives focus pullers not only a robust and reliable unit but one whose
ergonomics allow the focus puller to accurately translate the changes in actors' positions
on set to a precise movement of the focus knob.
Careful attention has been paid to protecting the unit from impact and environmental
damage. The microwave antenna is integrated within a form fitting cover. The iris slider
uses a magnetic sensor to eliminate the opening required for a conventional sliding seal.
The soft urethane handgrip and focus knob cover not only provide for comfortable all day
operation, but also protect the unit from shock.
Generation 4 (G4) transceivers address the challenges brought about by the proliferation of
wireless devices using the 2.4 GHz wireless band. Their new architecture results in a greatly
improved ability to reject interference from other devices operating in the same band as
well as out of band interference. The improvement in performance is quite significant,
typically 10x or better interference rejection than previous transceivers.
The HU3 and MDR3 can also be connected through a cable link using the command cable.
This provides high reliability communication over long distances (1km).
To address the metadata requirements of CGI, the MDR3 has motor position and camera
data available at the serial port for incorporation into a metadata stream.
Lens Mapping software matches the focus distance marks of a lens to the pre-printed
focus marking rings. Five focus rings, labeled A – E, cover focus distances from 9" (.35m)
to 6' (2m). The set of focus rings have large, easy to read, distance marks printed on a
