|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.|

Design and Features
Through the use of original optical design technology, this new type of telephoto lens maintains high performance while achieving the brightness of f/4 aperture, reduced size and weight and excellent operability.
Like the FD300mm f/5.6 S.S.C. (released in March 1973), the FD400mm f/4.5 S.S.C. (released in October 1975), the FD600mm f/4.5 S.S.C. (released in July 1976) and the FD800mm f/5.6 S.S.C. (released in July 1976), which were highly regarded for high performance and excellent operability, this lens utilizes the rear focusing system in which focusing is performed by moving the rear lens group back and forth, resulting in being lightweight and compact as it does not change the overall length even when focusing. The lens has the closest focusing distance in its class at 3m, and also has excellent metering functions through the use of the vari-pitch focusing system.
With regard to optical performance, the lens realizes the ideal power distribution based on the latest in optics to properly compensate for aberrations. In particular, spherical aberration resulting from different wavelengths and aberration changes in close shooting have been almost completely eliminated through rear focusing, successfully providing excellent image quality with high resolution and high contrast despite the large aperture.
