PHASE ONE IQ140 digital back for Mamiya mount, sold as is. Shooting and recording with 645DF•XF has been confirmed. The following issues exist: We have replaced the filter in front of the sensor, and we cannot guarantee the images completely. Errors may occur. When an error occurs, an image like the one in image 8 will be recorded. We have not checked tethered shooting, so it is unknown. The battery compartment latch is loose and cannot be locked. The cover latch is not a problem. Accessories: ・Battery ・Front cover If you have any questions, please feel free to comment. Thank you.
