Unlike the later "New" FD line this is a robust beast of a lens. It's all metal complete with gorgeous brass hidden inexplicably under black enamel. The design decisions from this period blow my mind. Also uniquely the lens features a concave front element making it very visually distinct. I got mine for a good price but the lens had some fungus on the inside which I had to clean. It's become one of my favorite lenses due to all of its unique attributes.
