Introduction
Cooke Optics Limited developed the/I Technology system to enable film and digital
cameras and equipment to automatically record and display key lens data for every
frame shot. Lens metadata includes information such as focal length, focus distance, T-
stop, Zoom, depth of field, horizontal field of view, entrance pupil position and frame
rate. Script supervisors no longer need to manually write down lens setting for every
frame shot. Power and data are transmitted through a camera interface, an external
interface or both.
