XPIMAGE Focal Reducer Adapter This adapter allows you to attach Mamiya 645 lenses to GFX cameras and use them with a 0.8x field of view. For example, if you use an 80mm lens with a GFX camera and this adapter, the effective focal length will be 80mm x 0.8 x 0.8, which is equivalent to approximately 50mm on a full-frame camera. I purchased this new on Amazon at the end of last year. The price has now increased to around 120,000 yen. This is a great opportunity to buy it at a good price. There are minor scratches from normal use, but none are visible, and the overall condition is good. It is highly recommended for those who are looking for a practical item. There may be some dust, scratches, and other imperfections inside the lens, but it is generally clean and I don't think it affected the photos. Fringing can be noticeable depending on the shooting conditions, but the image quality indoors (80mm F2.8N) is superb. If you are concerned about fringing, you can also get an adapter without a correction lens for worry-free outdoor use. I look forward to connecting with someone who will take good care of it. It has been stored in a dehumidified storage box. There are no pets or smokers. Please check the attached photos for details.
