This is a Konica close-up filter. AUTO-UP CA 100〜50cm It seems to have been found while organizing a room. The main body is missing, and the operation has not been confirmed. There is no case. It will be wrapped in cushioning material and shipped. In preparation for listing, I disassembled and cleaned it, but there are dust and scratches. (Photos 5 and 6) They appear depending on the angle of light, so it is unlikely to have a significant impact on the image, but I don't know because I haven't been able to test it. Please consider.
