This was the highest-end model, with a spring motor drive system, and it was intended as Canon’s symbol of movie camera technology. The goal was to apply 16mm-movie-camera technology in an 8mm movie camera. The fast f/1.2 lens was the first to apply Gauss for the relay lens based on the high-magnification and high-resolution lens of the Reflex Zoom 8-3 (marketed in 1962). This camera, with a variable shutter opening and spring mechanism enabling long time shooting, was called a “masterpiece” of movie cameras and was used for a long time by movie lovers, who wanted to produce high-quality movies.
