This is an adapter for attaching A-mount lenses to Sony E-mount cameras. When switching from an A-mount camera to an E-mount camera, I purchased this adapter new to use my existing A-mount lenses. I used it a few times indoors, but haven't used it since. It has been stored in a dry cabinet, so it's in near-new condition. There are no scratches and it's in excellent condition. Operation has been confirmed. The items included are all shown in the photos: - Adapter body - F cap - R cap - Storage case - Instruction manual - Serial number: 2011325
