Description — Canon 20mm f/3.5 Macro
The Canon FD 20mm f/3.5 Macro is a prime wide-angle lens built around the Canon FD mount, designed to cover full-frame SLR cameras. With a fixed 20mm focal length and a maximum aperture of f/3.5, it falls into the wide-angle focal length range while also carrying a macro classification. Focusing is entirely manual, consistent with the Canon FD system's design era, placing control firmly in the photographer's hands.
The lens features a 72mm filter thread, accommodating a broad range of photographic filters. At 320g, it maintains a workable weight for a wide-angle prime. Image stabilization is not present, so a steady hand or stable support is recommended in challenging lighting. This lens is a considered choice for Canon FD system shooters, film photographers, and manual-lens enthusiasts working on adapted mirrorless setups who value the specific combination of wide-angle perspective and macro capability.
