This is a K&F mount adapter, well-known among old lens enthusiasts. It allows the use of Minolta MD mount lenses (old lenses) on Sony NEX E-mount cameras. Since there are no electronic contacts, focus, exposure, etc., are all manual operations. The inside of the mount adapter is not treated for internal reflection. Infinity focus is supported. This is a new item. The original plastic storage case is not included. Please note that it will be opened before shipping to check for initial defects and to test the lens and camera attachment. A new lens cloth (15 x 15CM) will be included as a bonus. The mount adapter is not a genuine product of the manufacturer. Please research thoroughly before purchasing, as there may be lenses that are not compatible. If you have any questions, please contact me via the comments section.
