K&F CONCEPT mount adapter, Nikon F to Sony E mount adapter, is for sale. I was enjoying using Nikon's single-focus old lenses on my Sony a7c. I'm selling the adapter because I reluctantly sold my Nikon old lenses. I used it for about six months. I inspected and cleaned it before listing it. The body is clean with no noticeable scratches, marks, or dents. The mount also has no noticeable scratches, marks, or dents, but there are slight scratches from use. Also, there are three spots where the plating is peeling off on a part of the metal lens mount. There is no problem with use. I didn't even notice it myself when I was using it. Please refrain from purchasing if you are concerned. (See images 5, 6, and 7) What I am selling is the adapter body only. No case is included. I have set the price low, so thank you for your consideration.
