This is the first version F1 with 58mm threading. It is out of the package but it looks unused. We got this with a big lot of unused gear from a collector. The lens was mounted on a camera but I am not sure that either saw a roll of film.
The lens has both original caps (no shade or box). The mount has maybe the slightest scuff on the mount but is otherwise completely mint. The glass has no scratches, haze nor fungus. I do see a large speck of dust inside (not fungus). I will leave it the buyer to decide whether to have it removed.
I do not think that you will find a cleaner example.
