Conversion Mount Adapter This is a mount adapter for attaching M42 mount lenses to F-mount cameras. I was able to attach and shoot with a D610, but I'm not sure if it can be used with other cameras. Please note that this can only be used manually. From a layman's perspective, it appears there is no mold on the lens. Please consider that this is a used item, so there may be some deterioration such as scratches and dirt. I am also selling other camera accessories. I will discount 100 yen for combined purchases. If you have any questions, please comment. #CameraAccessories_Korosuke
