The Hand Unit 3 adds impressive new features and functionality to the system. It integrates its 30 channel 2.4GHz wireless link into a 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 need for sliding seals.

New software called "Lens Mapping" allows the focus distance markings of a lens to be matched to a set of five pre-marked focus scale rings. These rings differ in their minimum focus marks which range from 9" (.35m) to 6' (2m). The on-board lens library holds data for 100+ lenses, freeing the assistant from having to mark up individual rings.

A bright, sharp, organic LED 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.

Electronic focus marks can also be entered and displayed. A new bargraph display mode shows graphically the relation between the focus knob setting and any nearby focus marks.

The HU3 can control a stereo pair of lenses for 3D applications. "Lens Tweak" software matches the left and right lenses in focus, iris, and zoom.

Optional 3D rig software can be loaded into the HU3 allowing it to control both beamsplitter and side-by-side 3D rigs.

Hand Unit software updates can be downloaded from PrestonCinemaSystems.com via the serial receptacle located at the rear of the unit.





A new, unique feature called Lens Mapping eliminates the time consuming chore of writing distance calibrations on focus marking rings. The Hand Unit contains a Lens Library which can store calibration data for 150 lenses. When a lens is mounted to the camera, the user chooses it from the library. The Lens Mapping software precisely matches the distance marks for that specific lens to the distance calibrations on the Focus Ring.



Five pre-marked lens rings are provided with the unit. The rings, labeled A ­ E differ in their close focus distance calibration, ranging from Ring A having a 9" close focus to 6' for Ring E. Once a lens is calibrated, it can be used with any of the five lens rings provided with the unit.

The Lens Calibration procedure is fast and easy. The lens menu directs the user to enter the infinity mark and six additional distances. Enter the name of the lens and the procedure is complete. Lens data is organized into folders grouped by manufacturer name. The user is free to name the lens



A new bargraph display mode shows the relation between focus marks entered electronically and the setting of the focus knob. Focus marks are entered by pressing the "Set" key just below the display. This is illustrated below for a single focus mark set to 10'.

The vertical line at the center of the display represents the current setting of the focus knob. The height and width of the bar indicate how close the knob setting is to the focus mark, while the bar changes position from left of center to the right of center as the knob moves from the close to the far side of the mark.



Pairs of focus marks can be entered to indicate focus splits. The left hand image shows the height of the bars equal on both sides of the center line, when the distance between two focus marks is split equally.



The Hand Unit can program the camera speed and shutter angle for cameras featuring electronic shutters.



The Hand Unit can also monitor for the presence of other PCS wireless systems. The "Network" command scans the 2.4 GHz band and shows the channel and signal strength of any other active devices. Special operating modes can be selected to enable special application (Snorkel Mode, Multiple Camera controls, etc)



The HU3 supports both 3D rig control as well as 3D stereo lens control. Please refer to the Technical Notes section on our Downloads page for details.

The Hand Unit is powered by an FM3 Lithium-Ion battery. This provides an operating time of approximately 10 hours.

The zoom function is provided by a separate Micro Force control (either the analog V+F3 or Digital Micro Force2 version). A bracket attachment point is provided for rigid mounting of the Micro Force to the Hand Unit. Alternatively, the Micro Force can be connected to the HU3 via a cable connection.

The Remote Iris Control is a cable connected unit that plugs into the bottom receptacle of the Hand Unit.

The Hand Unit 3 can also be used with other FI+Z single channel hand units to operate the Focus, Iris, Zoom and/or Camera control functions in a completely wireless network.

Additional Display Options

The Cine Tape interface (p/n 4542) connects the remote receptacle of the Cine Tape unit to the Serial receptacle of the MDR2. Distance data is automatically displayed on the HU3. Similarly, Cooke i-Lens data is displayed when the lens is connected to the Serial port with cable p/n 4544.

Single Channel Hand Units



When activated, these three units take over their designated function from the Hand Unit. The Focus/Iris unit can be switched to control either focus or iris, the Radio Micro Force control zoom, and the F/X unit controls iris, camera speeds, shutter angles and speed ramps.
