The FDtoEF Canon FD series conversion kits are coming late Fall 2019. The Canon FD series lenses span about ten years from around the early 1970’s to the early 1980’s. Within this period Canon produced three different versions of breech ring FD lenses: The first version had a chrome plated front barrel (nicknamed “chrome nose”) and a green “o” for auto exposure.The second version had a black front barrel and still had a green “o” for auto exposure.The third version had a black front barrel, and a green “A” for auto exposure. (typically S.C. or S.S.C. lenses)Soon you will be able to convert these breech lock Canon lenses with our high quality metal conversion kits, retaining full aperture control and infinity focus without any degradation of picture quality and change in crop factor.

The product conversion FD to EF plates are built, but the aperture control links are still going to through some final design tweaks. Unlike the FDn aperture control rings which can be changed by simply swapping out the original Canon aperture control ring with our uniquely designed version, the FD series isn’t as simple.

Converting the FD series will require replacing the aperture control link, via two tiny M1.4 screws (included in the kit), so a steady hand and patience will go a long way. I’ll post a video to my YouTube channel detailing the conversion process and steps to avoid other complications. 

The Canon FD Conversion Kits should be ready to ship in September 2019. Look for more news and updates on availability in future.

FD55mm f/1.2 Chrome Nose
FD55mm f/1.2 S.S.C
FD55mm f/1.2 S.S.C Aspherical

The original Chrome Nose FD 55mm f/1.2 was first introduced in 1971 and has the same SSC coating as the S.S.C. version (marked “S.S.C”) introduced along with the S.S.C AL (Aspherical) version in 1973.

The FD 55mm f/1.2 S.S.C. the newer version of the Chrome Nose is a large aperture standard lens based on the optical system of the FL 55mm f/1.2. Despite its large aperture, it is highly reputed for its high contrast and stabilized image definition at full aperture opening. Because of its fast f/1.2 speed, it provides high image quality in low light level photography.

The FD 55mm f/1.2 AL (The abbreviation “AL” stands for the “Aspherical Lens”). The ground and polished glass aspherical surface is applied at the front surface of the second lens element. This aspherical lens makes central and peripheral light converge on a single focusing point to correct aberrations. High contrast definition is obtained even at the maximum aperture of f/1.2.

The FD 55mm f/1.2 S.S.C. Aspherical introduced in 1975 is a specially developed large aperture standard lens that uses an aspherical surface glass. This lens provides the highest contrast, even in the corners.

FDn to EF conversion plates are now electroless nickel plated.

That’s right the FDn to EF conversion plates are now electroless nickel plated. Besides looking good they are now stronger, and easier to mount. The problem with some materials is that the rotation action required to mount the lens on the camera, causes friction. The amount friction is influenced by several factors, one being the material type. The electroless nickel plating reduces surface friction allowing for the mount glide across the body mounting plate. Our new plated conversion plates have a similar feel to the original Canon EF lenses.
