Abstract
An adapter is provided by which an image formed by the eyepiece of an optical viewing device such as an endoscope can be simultaneously viewed and photographed with a motion picture camera of the type having a reflex viewing system which has an entrance pupil that occupies only a portion of the camera objective taking lens system and which is offset with respect to the optical axis of the camera objective taking lens system. The adapter operates to align the center of the viewing device exit pupil at a predetermined point along a line connecting the centers of the camera objective lens system and viewing system entrance pupils to preclude vignetting of the camera viewing system entrance pupil.
