Canon FL 1200mm Lens
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 lens A camera lens (also known as photographic lens or photographic objective) is an optical lens or assembly of lenses used in conjunction with a camera body and mechanism to make images of objects either on photographic film or on other media capa ...es: 400mm f/5.6, 600mm f/5.6, 800mm f/8, and the 1200mm f/11.See description text in https://global.canon/en/c-museum/product/fl121.html and note identical rear section in the documentation picture in https://global.canon/en/c-museum/product/fl122.html 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.

Canon FL
Canon FL refers to a lens mount standard for 35mm single-lens reflex cameras from Canon. It was introduced in April 1964 with the Canon FX camera, replacing the previous Canon R lens mount. The FL mount was in turn replaced in 1971 by the Canon FD lens mount. FL lenses can also be used on FD-mount cameras. Many mirrorless interchangeable-lens cameras are able to use Canon FL lenses via an adapter.

Convertible Lens
A camera lens (also known as photographic lens or photographic objective) is an optical lens or assembly of lenses used in conjunction with a camera body and mechanism to make images of objects either on photographic film or on other media capable of storing an image chemically or electronically. There is no major difference in principle between a lens used for a still camera, a video camera, a telescope, a microscope, or other apparatus, but the details of design and construction are different. A lens might be permanently fixed to a camera, or it might be interchangeable with lenses of different focal lengths, apertures, and other properties. While in principle a simple convex lens will suffice, in practice a compound lens made up of a number of optical lens elements is required to correct (as much as possible) the many optical aberrations that arise. Some aberrations will be present in any lens system. It is the job of the lens designer to balance these and produce a des ...
