Vintage Auto Chinon 55mm f/1.4 lens (M42 thread).
​Focus ring is smooth and the aperture blades work fine. Glass has some balsam separation around the edge and a few light cleaning scratches on the front (tried to show this clearly in the photos).
​Comes with its fitted case.
​Works great adapted to modern cameras. Any questions just ask!

please note this item was taken from house clearance if you need any more pictures or want any more questions please ask me I am not a lens expert I just have figured out what I do know and asked AI about the rest there are some scratches looking through the lens that is the thing I want to make people most aware of to me I don't think they affect actual use that much
