This is a K&F mount adapter, well-known among old lens enthusiasts. It allows the use of old Exakta mount lenses on Sony's NEX E-mount cameras. Please note that some lenses may not be compatible due to interference with the aperture lever, etc. Since there are no electronic contacts, focus and exposure must be manually operated. 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 for initial defect checks and to test the lens and camera attachment. A new lens cloth (15 x 15 cm) will be included as a bonus. The mount adapter is not a genuine manufacturer product. Please research thoroughly before purchasing, as some lenses may not be compatible.
