Canon FD 100mm f/4 Macro - Canon FD Mount

The Canon FD 100mm f/4 Macro is a manual-focus telephoto lens capable of 1:2 magnification natively, or 1:1 with the appropriate extension tube. It is known for its high optical resolution and flat field of focus, making it a reliable choice for close-up photography and portraiture on film or adapted mirrorless systems. The robust construction is typical of the FD era, featuring a dedicated focus scale with magnification ratios. On the used market, the primary concern is the smoothness of the long-throw focus ring, which can become stiff if the internal grease has dried. We inspect the iris blades for oil contamination, which can cause slow response times. SDS also checks for internal haze and fungus, which are common in vintage optics, and ensures the breech-lock or New FD mount engages securely.
