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.
1
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.
2
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.
3
OV1 Video Overlay Unit
The Focusbug OV1 is a compact inline video processing unit that inserts between the camera’s SDI feed and the focus monitor, outputting real-time Cine RT and LCS data via a real-time customizable overlay.
4
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.
5
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.

🎬 ARRI nos recuerda por qué la ALEXA 35 sigue siendo la reina: SUP 6.2.0, y esta vez los grandes ganadores son los focus pullers.
La actualización es para la ALEXA 35, 35 Xtreme, 35 Live y la ALEXA 265 (sí, la de 65mm), y trae tres cosas que se agradecen en set:
🎯 Focusbug Cine RT directo a la cámara. Antes, para usar este rangefinder ultrasónico con la ALEXA 35 y la Hi-5 necesitabas un adaptador RIA-1 o un LCUBE CUB-1. Ahora la cámara y la Hi-5 se comunican de forma bidireccional con el sistema Cine RT por el puerto SERIAL, y todas las funciones cubiertas por la licencia Focusbug para Hi-5 y Hi-5 SX funcionan sin caja extra. Una pieza menos en el carrito 🙌
📍 Focus marks compartidos. Puedes marcar foco desde un botón programable de la cámara o desde la Hi-5, y las marcas se sincronizan solas. Aparecen en el EVF y en los overlays SDI, junto con lecturas de distancia en vivo del rangefinder. Ojo: una marca nueva puede tardar cerca de un segundo en aparecer.
📺 Depth of field ramping para producción en vivo. La cámara compensa la exposición automáticamente mientras mueves el iris, así que puedes cambiar la profundidad de campo entre primer plano y fondo en plena transmisión sin que el brillo se mueva.
Eso sí, hay letra chiquita que me gusta que ARRI diga de frente: como esto cambia el EI dinámicamente dentro del clip, algunas herramientas de postproducción podrían ignorar o malinterpretar esa metadata. Y con grabación ProRes en espejo puede haber flicker o escalonamiento.
También trae detalles finos: prefijos “SDR” y “HDR” en los looks multicam (para distinguirlos en paneles con pantallas chiquitas) y un nuevo SDI Play Mode para reproducir clips HFR a rango de proyecto o al frame rate grabado.
⚠️ Recomendación de ARRI: actualicen, pero NO en medio de una producción. El proceso toma hasta 20 minutos, requiere un factory reset y hay known issues que conviene leer antes.
¿Ya le entraron al 6.2.0 o esperan a que termine el rodaje? 👇

Attention all Small HD users with RX enabled monitors! With Page OS 6.3.5 you can now select wireless as the general input, cable out from SDI 2 into the Focusbug OV1 and back into SDI 1. Then on an individual page you add a tool “input”, select SDI 1 and enjoy the OV1’s range of customizable overlay options using data from the Cine RT System and compatible lens control systems (ARRI, c motion, Preston and Heden). Thanks to @wizard_of_buzz for the image and assistance!
We made it inside… Well, in a manner of speaking…
With ARRI SUP 6.2 for cameras and SUP 3.6 for the Hi-5, the features of the ARRI Focusbug License are now supported directly via serial connector of the ALEXA 35, ALEXA 35 Xtreme and ALEXA 265. No more need for an LCUBE or a RIA-1 to access user buttons control of the Focusbug from the Hi-5!
Please ensure you are using a Bidirectional Serial or Y Cable to connect your Cine RT Base Sensor available from Focusbug. These cables work with both ARRI camera serial and RIA-1 serial inputs.
In addition to this update, keep an eye out for expanded Focusbug License features that will enhance control of the Cine RT from the Hi-5 and optimize support of the Focusbug OV1 for ARRI LCS users - coming soon from our friends at ARRI ECS!
