Focusbug Technologies Inc. developed the Cine RT System to provide ACs with solid subject distance data and enable them to get traditional focus marks quickly and discreetly. Our goal was to create a tool that would eliminate the need to pull tape or sight lasers and dispel the notion that there is no time to get useful marks. We quickly realized that a multi-faceted approach to the use of ultrasonic technology and native RF communication within the Cine RT would expand its versatility as a measuring device. The system's proprietary software was built from the ground up, tailored to the unique requirements of focus pulling.
