P. Angenieux Paris 35mm f2.5 Retrofocus Type R1 Lens for Exakta Mount -Read-
This is a beautiful wide angle lens by Angenieux, a legendary lens company. Their lenses are typically talked about in the context of the cinema industry, but their stills lenses are just as high quality. This one would make an excellent addition to a classic Exakta kit or adapted to mirrorless for video.
This one is in good condition with moderate wear. There seems to be some slight crazing of the coating on an inner element that looks slightly like ceramic glaze after it has hardened and separated a bit but much less severe (see photos). There is also a very slight haze on the front element. These may soften your images slightly when shooting in harsh conditions. There are also some very light cleaning marks on the front element but I cannot see them without a flashlight, they won't affect your image quality. Otherwise the glass is clean and scratch free and the aperture and focus are smooth.
