Lens ring has been used, but it looks and works good.  It has minor scratches from use. I don't see any dents. It works good. Threads are not damaged, or bent.

Lower Holder ring (that screws in on the lens) has 24mm OD (for series IV filters ), and retaining ring has 25.5mm threads .  Please note that adapter will be mailed as pictured.
