Measuring distance just became easier with the Cinematography Electronics CINE TAPE MEASURE System. This versatile ultrasonic system continuously calculates the distance between a subject and the camera's film-plane. By continuously measuring distance during a shot, small or subtle subject movements are no longer a problem. With non-stop measurements, focusing a camera lens is simplified which saves time, avoids retakes and reduces production costs.
