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.

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.

Shooting on location always has a special magic in the frame. We were in Xinjiang, China, at the end of June 2025. We decided to shoot during the magic hour—at sunrise and sunset—trying to create something unique for every shoot with the stunning professional model alinkablazhina . Here are 8 shots from the many we took over those days. I operated the Trinity stabilizer to keep everything smooth and especially efficient, given the remote location, tight timing, and windy weather by the end of the day.

And to wrap up the year, the last project of 2025 an experience that, more than adding flight hours to my profession, has left a sweet feeling of having been lucky enough to meet such beautiful people during an 11-week journey. I’m grateful to tgpatri claudiamallart and lamolins for the opportunity to be part of this crew; to the entire camera team; and to the other departments Art, Make-up, Wardrobe, Production, Direction, Grip & Light. Every single one of you, without exception, created a truly wonderful experience.

Wishing everyone great success and good luck.🙌🏼✨
