Frequently Asked Questions
The Focusbug Cine RT is a precision ultrasonic rangefinder system designed for modern cinematography. It acts as an invisible, real-time tape measure that helps the first assistant camera maintain sharp focus on high-stakes film sets. By using a computational ecosystem of hardware, it provides surgical precision that is essential when working with unforgiving high-resolution sensors and large-format glass where even a one-inch error can ruin a take.
The system consists of four primary hardware components that communicate over a 2.4 GHz ISM band at distances up to 800 feet. These include the Ultrasonic Base Sensor, which serves as the brain on the camera, and the Handset Control Unit for remote command. Additionally, the setup features a High-Bright LED Display for quick visual references and the Bug Ultrasonic Transmitter, a small device that can be hidden on an actor.
The Bug Ultrasonic Transmitter is a tiny device that can be placed in an actor's pocket to allow for constant tracking. Unlike older ultrasonic systems, this setup enables the first assistant camera to track subjects accurately even when they move behind obstacles or turn away from the camera. This technology ensures the camera remains locked on the subject's position in real-time, providing a reliable alternative to traditional physical tape marks.
On fast-moving film sets with complex gimbal rigs, physical tape marks and manual measurements are often luxuries that crews cannot afford. The Focusbug Cine RT provides an invisible tape measure that tracks subjects with surgical precision in real-time. This efficiency is vital for first assistant cameras who must ensure perfect focus for high-resolution sensors, where traditional methods might be too slow or imprecise for unpredictable movements.
