"The Focusbug Cine RT is literally my guardian angel. Since I owned my unit, it’s really hard to think about getting on set without it. Sometimes I wonder if there’s a face detection system build in since it is so accurate. Really feels like I’m working with a partner."

"The Cine RT is hands down the best ultrasonic measuring system available. Conceived and designed by a focus puller for focus puller’s, it’s incredible accuracy, functionality, versatility, and dependability are unsurpassed as is its build quality."

"Even if the Cine RT didn't have all the incredible features it has, it'd still be worth buying for sheer efficiency on the camera build. But it DOES have all those other features: The BUG, the remote-controlled Sensitivity and Limits, and especially Tape Mode are all changing the way I do my job!”

"The Cine RT has been a game-changer in helping me work faster as a 1st AC. The ability to walk out and get up to eight quick marks on the handset is worth the system price itself."

"The CineRT has become a staple of my focus toolkit. With the CineRT Handset, you simply walk into the room, make a couple of taps on the screen and all the information is right there.”
Duncan Vogel1st AC (Canada)
"The game-changing CineRT is the most comprehensive focus pullers aid in the world. With its BASE SENSOR's single Y Cable serial connection to my MDR, its ability to ignore the matte box through setting a custom Limit, its BUG Transmitters that can be magically seen through clothes and crowds, and its big, bright, stick anywhere HIGH-BRIGHT... I love it."

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.
