This is a Fotodiox Pro mount adapter. It's for attaching PENTAX 67 mount lenses to Fujifilm GFX series cameras. I purchased it new for around 23,000 yen. - There are scratches and minor imperfections on the exterior from use (see photos). - Actual operation has not been confirmed. - Please refrain from purchasing if you are sensitive to used items. - The included accessories are all shown in the photos. It's well-made and recommended for those who want to enjoy the image quality of medium format lenses on the GFX. Shipping will be done with careful packaging using cushioning material.
