This is a KIPON Baveyes CONTAX645-GFX AF 0.8x mount adapter. Includes the adapter body, front and rear caps, and the original box. This is a focal reducer adapter that allows you to attach Contax 645 lenses to Fujifilm GFX mount cameras. I purchased it new about a year ago directly from KIPON and have used it a few times. It has been stored in a dehumidified cabinet. I have confirmed AF operation with the GFX50S II and 100S II, and the focus accuracy is good. You can use the Planar T* 80mm F2 with a similar angle of view on a digital camera. Everything in the photos is included. Please be aware that this item is also listed elsewhere and may sell out. Thank you for your understanding. As of October 19th, the KIPON website lists this adapter for "$1,580.00," which is approximately 230,000 yen. Considering the added costs of customs and shipping, and the 2-3 months it took for me to receive it, this is a good option for those considering purchasing it. It is in very good condition, but there may be minor scratches that I have overlooked. Please understand this before purchasing. ※ To protect against damage during shipping, I will take photos and videos of the item in operation before shipping. If any problems occur, I will contact the platform to initiate the necessary procedures. ※ If fraudulent claims or item swapping are discovered (including attempted fraud), I will report it to the police, the Consumer Affairs Agency, and the platform, and take legal action, including charges of fraud and attempted fraud.
