The Canon FL 1200mm f/11 was a super-telephoto lens marketed by Japanese optical manufacturer Canon in June 1972. It was the longest super-telephoto lens in the Canon FL system. The lens was part of a group of four convertible lenses: 400mm f/5.6, 600mm f/5.6, 800mm f/8, and the 1200mm f/11. The lenses were in two parts: a focusing and aperture control section which mounted directly to the camera using the Canon FL breech-lock bayonet mounting ring; and the head end, which determined the focal length of the lens. The control section was common to each of the four head-end sections. The 1200mm head end was a preset aperture type, so the lens had to be stopped down manually for exposure.
