This is for SONY A-mount. I bought it for my own camera, but as a beginner, I accidentally bought the wrong one. The size was different, and I couldn't attach it to my camera, so I'm selling it. I only tried to attach it to the camera (of course, I didn't force it, I did it with someone who knows more about it) It should be almost the same as when I bought it. I will quote part of the text from the person I bought it from the other day below. [Condition] ■ Appearance The exterior is very clean with almost no scratches from use. There are no other noticeable large scratches or dents. The mount has almost no scratches and is very clean and shiny. The lettering is clear and vivid without fading. The overall texture is good, and it maintains a very good condition. ■ Optics The inside of the lens is clear with almost no dust or debris. There is no mold or clouding that would affect shooting, and visibility is good. Both the front and rear elements have no scratches, and the coating is clean. The operation is smooth, and the ring is also smooth. [Accessories] All items shown in the photos. Thank you very much. Mount...αA mount system
