|FD||The lens is designed for Canon 35 mm film SLR cameras and is not compatible with Canon EOS digital SLR cameras due to shorter flange focal distance of Canon FD mount.|
|S.S.C.||The Super Spectra Coating is applied to the surface of lens elements. It boosts light transmission, ensures sharp and high contrast images, minimizes ghosting and flares.|
|FISHEYE||Fisheye lens designed to provide 180-degree field of view.|

Design and Features
A large aperture full-frame fisheye lens with 180° diagonal angle of view. This lens had the world largest aperture of f/2.8 in its class at the time. This lens is called "full-frame fisheye lens" to distinguish from circular fisheye lenses, which produce circular images that do not fill the entire frame.
This is a fish-eye lens for general photography developed to follow the 7.5mm one. It is the smallest fish-eye lens in the world. It was developed as one of the FD lenses and consequently it has an extremely high quality of performance.
Because of its retrofocus design, the mirror does not have to be set upward. From the point of view of light metering, as well as photography in general, it operates as well as a standard lens.
Its f/2.8 brightness ranks well above the best, and it has full compensation of every aberration in the total 180° area. Special effort was done to enable it to avoid the aberration of magnification, and it has a sharp delineation up to the corner areas. Furthermore, in order to solve the problem of ghost and flare which tend to occur with this type of lens, the procedure of multiple coating was employed.
It will actually focus closer than the minimum focusing distance of 0.3m on the lens scale, enabling closest shooting distance of 0.2m at smaller aperture. As filters cannot be attached to the lens front, four filters, SKY, Y3, O and R are built-in.
