Canon FD 35mm f/2
The Canon FD 35mm f/2.0 lens was manufactured by Canon for the FD lens mount. It was sold in a number of variations over the years, and was the fastest Canon lens in the 35mm focal length before the debut of the EF 35mm f1.4.
Breech-Lock Mount (FD)[]

- Chrome Bayonet Mount, Convex Front Element, SSC Coating, Min Aperture f/22
Bayonet Mount (nFD)[]
With a 10-element, 8-group construction, the new FD 35mm f/2 was approximately 25 percent shorter and 29 percent lighter than the earlier FD design.
- Black, Convex Front Element, Standard New FD Coating, Min Aperture f/22[4]
Thorium[]
The f/16 versions of the lens had some optical elements which contained the radioactive element Thorium creating concern that these radioactive elements may not be safe.[5] The Thorium lenses were considered sharper side-to-side and at all apertures than any subsequent version.[citation needed] This seems to be as due to a superior optical design enabled by the inclusion of Thorium dioxide glass with enhanced refractive indices. The thoriated glass elements in this lens over time develop a yellow tint reducing transmission and interfering with neutral color reproduction.
