Canon FD 35mm f/2 (Thorium)

Canon FD 35mm f2 with concave front element. Lens known as radioactive, due to the usage of rare earth element Thorium or Lanthium. Lens is visible yellow, and this can be cured by exposing it to the UV light, but I don't want to, as it makes nice yellow filter for BW. I am mentioning it, just because it does slightly reduce resolution.
