Operation confirmed with Schneider 80mm lens. The digital back is almost unused. There are no scratches on the sensor. There is a crack in the IR filter due to long-term storage. * Repair by a shop would cost around 10,000 to 20,000 yen. * Purchase on eBay for around 5,000 yen and replace it yourself. * Alternatively, removing the IR filter and using it as a monochrome-only camera like the IQ3 is also recommended. By purchasing a digital back adapter (10,000 to 40,000 yen), it can be used with Hasselblad H, Hasselblad V, ALPA, technical cameras, Contax, RZ67, etc.
