Carl Zeiss jena Biotar 2/58mm prime lens, m42 screw mount.

Vintage, used not brand new.Sold on the basis for spares/renovate/service/project. No returns.

Optics have some dust/debris/marks although I couldn't see fungus?

Front filter ring has a couple of dings, can just about attach a filter but doesn’t fit fully in.

Focus is stiff but usable.

Preset spring aperture ring operates with a little play. Aperture blades clean/dry.

Externally as shown, tarnished and marked.

Despite this description I have shown some example photos taken with this lens in its current condition adapted to my fuji mirrorless camera, wow! sharp and contrasty.

If you are someone who can use/live with this lens as is, fine. A service/clean would yield rich reward. I'm not inclined because I don't intend to keep and I'm already covered in this area with similar lens.

If you are not sure about my description, pls do not bid, no returns.

I'm happy to consider offers/negotiate.

Comes as lens only and will be well packed.
