Cosmetic Condition:

Lens has been used, but it is in very good cosmetic condition. It looks very nice. I don't see any noticeable scratches on front or rear glass coating. I don't see any haze or fungus inside.  I'd say glass looks very nice over all. Glass is very clean and bright.

Manual focus is smooth, without any play. Zoom works good.
