The Cine RT System

The Cine RT System is one of the most popular distance reference tools available to professional focus pullers, and the best ultrasonic cinema rangefinder & transmitter tracking system in its class.

Designed by camera assistants

Widely recognized for its operational flexibility and exceptional performance, the Cine RT satisfies a broad range of working methods on film and digital cameras.

Purpose built components

Our components are constructed from pro-grade materials and electronics rated to work within industrial operating temperature range - built to withstand a life on set.

Expansive toolset

The innovative distribution of ultrasonic transducers across the custom-built wireless component family enables an expansive toolset unique to the Cine RT.

LCS Integrations

Custom-designed and third-party serial protocol outputs deliver fast distance data to lens control systems by ARRI, Preston, c motion, Teradek, and Heden.

The System Package

The component family enables multiple working modes to display real-time subject measurements and facilitate the collection of focus marks. 

Ultrasonic Base Sensor

The lightweight, low-profile ULTRASONIC BASE SENSOR is the computational center of the Cine RT System and the only system component required on the camera, making it ideal for all camera builds.  

Handset Control Unit

The HANDSET CONTROL UNIT is both a remote command centre and a handheld tape measure. It contains a pressure-sensitive touchscreen to access system-wide operational settings and display multiple distance readout modes.

Multiple

Use multiple displays

High-Bright LED Display

LCS Integration

The Cine RT System’s utility goes even further by connecting to all popular lens control systems. Custom or native serial protocols deliver fast distance data to products by ARRI, c motion, Preston, Teradek and Heden. In 2022 Focusbug’s partnership with ARRI advanced the integration to include the Focusbug License for bi-directional operational compatibility with the Hi-5 focus handset.
