The FI+Z system controls
the complete array of both lens and camera functions. It consists
of the HU3 hand unit, a set of Digital Motors, a Micro Force zoom
control, and optional controls including wireless Focus/Iris, and
Zoom for splitting of functions from the main 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.
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. In addition, their lower
power consumption doubles the operating time of the HU3 on battery
power compared to its predecessor. The latest "Blue Dot"
version of the transceiver adds channels 30 – 59. These new
channels allow FI+Z units to operate in very close proximity (<1m)
New software called "Lens Mapping" matches the focus distances
of a lens to a set of five pre-printed Focus Marking Rings. These
rings differ in their minimum focus distance from 9" (.35m)
to 6' (2m). The on-board lens library holds data for 255 lenses:
lens changes require only the few seconds to choose the lens from
the library. Lens calibration is fast and doesn’t require
connection to an external computer. The primary references for the
focus puller are the distance marks on the focus rings. The set
of focus rings have large, easy to read, distance marks printed
on a bright fluorescent background for excellent visibility under
all lighting conditions. The rings are automatically illuminated
in low light conditions by a pair of white LED's.
Lens mapping also supports the upcoming Light
Ranger 2, a powerful tool which enables both precise
focusing in both manual as well as autofocusing modes.
A bright OLED display shows camera, lens, and Hand Unit set-up status.
Focus settings can be displayed digitally for Cooke i-Lenses, or
any lens which has been calibrated to the unit. Multiple focus marks
can be displayed in a new focus display mode called "show".
This mode gives an easy to interpret bargraph representation the
distance set by the focus knob and any focus marks entered by the
An integrated hand grip and molded focus knob grip imparts comfortable
operation. The zoom bargraph shows both the zoom lens position as
well as user set end limits. End limits are set with Set/ Reset
tactile switches arranged in three groups. An LED in each group
indicates when limits have been set.
Power is provided by widely available FM-500H Li-Ion batteries.
The Motor Driver MDR3 accepts commands from the Hand Units
connected via the wireless microwave link or cable, and controls
up to four digital motors as well as camera functions for both film
and video cameras.
Three sizes of digital motors meet the needs for virtually any lens
drive application. The DM1X Digital Motor (left) has the highest speed
and power of any available lens motor. It is specifically intended
to focus cinema lenses, allowing for quick focus racks on even the
largest zoom lenses.
The DM2 motor (middle) is general purpose motor, intended to perform
the Focus, Iris or Zoom functions on all but the stiffest cinema lenses.
(These jobs should be relegated to the DM1X.)
The DM4X motor (right) is the smallest member of the family. It’s
recommended for either light-weight video lenses or the zoom / iris
rings of small zoom or prime lenses.
The DM1X and DM2 motors are both available with an integral bracket
(the “A” version), while the DM4X comes with the integrated
bracket only. The integrated bracket provides for simplified mounting
and also allows the motors to be positioned very close to one another.
A rosette gear securely locks the swing arm in position. The swing
arms clamp to 19mm rods. Step-down bushings accommodate 15mm and
0.635” rods, p/n 4320 and p/n 4321 respectively.
DM1X and DM2 Digital motors can be mounted to matte box support
rods with either the integral motor mounts as described above or
with separate swing-arm brackets. All of the brackets have one 15mm
opening for the motor rod and one 19mm opening for a matte box rod.
Additional step-down bushings are required for 0.625” Panavision
rods and 15mm rods.
Swing-arm Brackets are provided in two groups: short brackets for
the Panavision vertical rod configuration and long brackets for
Arriflex style horizontal rod configurations
Motor Cables are available with both straight and right
angle LEMO configurations. The right angle configuration is used
when minimum cable outline is most important - for example in Steadicam
Camera Cables allow the Motor Driver to control both the
start/stop, speed, and shutter angle function for film cameras and
the VTR function for digital cameras.
Additional hand units allow camera and lens control functions
to be split off from the main hand unit. Using these tools, each
crew member can position him/herself wherever it is most advantageous.
The Focus/Iris unit takes over the iris or focus function
(switch selected). The Radio Micro Force module together
with a Micro Force control splits off the zoom function.
