Arri Tape UDM-1

The ARRI UDM-1 is an ultrasonic distance measurement system designed to assist focus pullers in achieving precise focus on set. By measuring the distance between the camera's sensor plane and the subject, it provides real-time distance readings to help maintain accurate focus during complex camera movements and demanding shooting situations.

Compatible with a wide range of professional camera and lens control systems, the UDM-1 can display distance readings on compatible ARRI hand units and supports focus tracking with selected camera configurations. It is an essential tool for narrative films, commercials, and productions requiring precise focus control.
