Selling an ALPA Kern-Macro-Switar 50mm f/1.8 AR. It's a wonderful lens that can be used in modern mirrorless cameras with the included adapter.
The lens is in excellent conditions, it shows marks of use on the body but the glass is clear from damages and fungus.
It comes with its original Lens cap, with the meatbones adapter ALPA to Sony e mount, but not with its original bottom cap.
