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.

System for sensing and displaying lens data for high performance film and video cameras and lenses

A video monitoring system for a movie film camera usable with either spherical or anamorphic lenses wherein conventional, unmodified video monitors and recorders may be used. A video camera is positioned in the film camera to receive an image directly from the camera lens without interposing either a ground glass for imaging or an optical deanamorphosing lens. The anamorphic image, which is horizontally squeezed (such as by a factor of 2), that is received by the video camera then is electronically processed to deanamorphose the image by producing an analog video signal to a video monitor that displays the properly proportioned image in the middle one-half of the monitor screen and produces black areas or strips across the top one quarter and bottom one quarter of the screen. The horizontal lines of the video picture are electronically interpolated for enhancing the picture.
