A system for sensing and displaying lens data for a cinematography zoom lens and camera in real time. A plurality of sensors are connected to the lens for producing signals continually representing the present positions of focus, zoom and T-stop setting rings of the lens. A range finder is positioned adjacent the lens for producing a signal representing the distance from the lens to an object located in front of the lens. A printed circuit board with a microprocessor receives and processes the signals and has a memory with data representing the focus, zoom and T-stop characteristics of that lens. A display device is positioned adjacent the lens and selectively displays indicia representing the positions of the focus, zoom and T-stop settings, the distance to the object and the depth of field.
