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
The compact HIGH-BRIGHT LED DISPLAY receives data remotely from the BASE and relays distance information with ultra-bright LED numbers.


Ultrasonic Bug Transmitter
The miniature ULTRASONIC BUG TRANSMITTER is milled from rugged ABS, weighs virtually nothing and can be easily hidden under most fabrics.

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.
The Focusbug Community
The Focusbug Cine RT System was introduced in 2017 and, with over 1800 units in the field, has become an industry standard. The system has been used on a wide range of productions, from music videos and documentaries to large-scale award-winning films like Dune, Napoleon and Oppenheimer. We thank our user base for their support and ongoing dialogue, which inspires us to continue to evolve the Cine RT to further complement the toolkit of any 1st AC. We are proud of our users and love to feature their posts and stories.

Eigentlich die angenehmste #filmcamera für die #steadicam X die #alexaminilf
Nur zum parken kommt der Akku hinten dran, beim fliegen kriegt sie die nötige Power über mein #betzrighd und bleibt dadurch leicht und kompakt.
