Preston F/I Single Channel

The Focus/Iris (F/I) unit is a wireless, single channel control. It can be used with the FI+Z system to take over the Iris or Focus function from the FI+Z Hand unit. When the F/I unit is powered, the FI+Z motor driver recognizes its presence and gives it control of either the Focus or Iris function of the FI+Z Hand unit as selected by the user.

The module has a bright LED bargraph display of lens position. End limits can be set with the touch of a button and are shown as illuminated bars. A tri-color LED is used to indicate signal strength. Additional LED displays show the radio channel, power /battery status, and camera run/stop indication.

Additionally, this unit can also be used in conjunction with the Radio Dimmer unit (p/n 5010) to control both LED Eye-Lights as well as Kino Flo lamps.

A soft urethane grip makes for comfortable operation and solid ergonomics. Marking discs slide over the knob onto an index pin. Power is provided by a FM-500H Li-Ion battery, allowing for approximately 8 hours of operation.
