Cleaning a fast Canon FD lens affected by fungus, with special attention to coatings and reassembly.

The Canon FD 55mm f/1.2 S.S.C. is a lens worth treating carefully. Its speed and rendering make it desirable, but the large glass surfaces can show fungus clearly.The job requires precise disassembly, clean handling and careful alignment during reassembly. The aperture and focusing feel are checked again before the lens leaves the bench.After cleaning, the remaining value depends on how deeply the fungus had attacked the coating.
