This is a K&F mount adapter, famous among old lens enthusiasts. It allows you to use Exakta mount lenses (old lenses) on Fujifilm X mount cameras. Please note that some lenses may not be usable due to interference with the aperture opening lever, etc. Since there are no electronic contacts, focus and exposure 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 us via comments. Free shipping, shipped via Yu-Packet Post Mini. No plastic case for storage is included. It will be wrapped in bubble wrap and shipped in a Yu-Packet Post Mini envelope. Same-day shipping is basically not possible. Also, shipping is not available on weekends, holidays, and festivals.
