    Ultrasonic Distance Measure UDM-1

    0,00 kr

    The UDM-1 measures distance between the film/sensor plane and objects using ultrasonic pulses. It is compatible with all cameras.

    The measuring range can be configured via the display unit. This allows exclusion of objects that are irrelevant for the focus pull or those delivering confusing values to the camera assistant.

    The UDM-1 includes a sensor module and display unit that indicates the measured values on a transflective (LCD) screen. When used with ALEXA Plus or Studio cameras (or the UMC-4 Universal Motor Controller), the measured distance will be instantly displayed on the WCU-4 hand unit. The UDM-1 also enables ALEXA Plus or Studio cameras and the UMC-4 to automate focus tracking by setting the focus motor to continuously follow measured distance of a subject in the frame.
