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.

I would like to tell you more about the first day and preparation for the process shot. Initially, we did not have any specific understanding of what these frames would look like. But we knew what we wanted and the first day was dedicated to it.
We were bored to erect a structure so that the camera was fixed on the ATV and a screwdriver was fixed in front of the camera. Initially, it was planned that we would attach the corn clove to the screwdriver, but when we assembled the structure and saw what frames we got, we decided to refuse the corn cob and instead we can use pineapple.
At the same time, the creative group was engaged in the search for locations for shooting, and we did not fully know what locations we would have and whether the ATV would be able to move there, so as a backup option we made the design in manual execution.

The Cine RT System doing another tour of duty on the Dune series - brought along by 1st AC Jorge Sanchez and seen here on DP Linus Sandgren’s camera.
The picture appeared in an article by the Hollywood Reporter offering a little insight into the look of the project: “I envisioned lenses that could create specific optical characteristics, particularly the flares, that would be unique to this film,” said Sandgren. “Atlas rose to an incredible challenge, designing and hand-crafting these IMAX lenses in remarkable time…”
Looking forward to this one!

It was an expedition to Kazakhstan, we were there for three days. We brought a camera and optics from Moscow. We planned one full shooting day, the second was a pick-up day.
Upon arrival in Kazakhstan, we had a prep day, we needed to prepare for the process shot. We had to attach the camera to the bug in order to shoot how the camera would catch up with the actor.
On the first day of shooting, we had three lactations planned, a large number of frames, the total duration of the shooting day was 22 hours.
