The Canon FD 35 mm f/ 2 S.S.C (II) is a high-quality fast wide-angle lens for Canon FD film SLR cameras.
This is the second update version of the lens. As different from the previous version, it has a smaller aperture (22 vs. 16) and weight. Besides, this version does not use radiothorium.
Earlier on, Canon lenses of this series used thorium, a rare-earth element. Thorium was added to bulk glass to increase a refractive index ( as a rule, a high refractive index causes high dispersion).That allowed manufacturers to make lenses thinner. In the 1970s thorium was replaced with some other safe elements.
In due time the Canon FD 35 mm f/ 2 S.S.C used to be Canon's standard-bearer. It was one of the first lenses with "the system of floating elements".
The S.S.C. abbreviation (for Super Spectra Coating) means that the then revolutionary technology of lens coating was applied by Canon for increasing optical transmission, decreasing flare, and achieving natural color balance.
The Canon FD 35 mm f/ 2 S.S.C (II) is incompatible with the modern Canon EF system because of its construction and flange focal distance.
