Carl Zeiss Jena G1/M77 Yellow Lens Filter ★ Deadstock ★ Hard-to-Find Old Lens ★ Mirrorless Camera SLR Camera Carl Zeiss Jena G1/M77 yellow lens filter, new but only what is shown in the photos. My grandfather kept it in a lens storage for many years, protecting it from moisture, dust, and mold, but I am not familiar with it, so it appears to have no problems with the lens or operation by visual inspection, but if you are concerned, please be sure to ask questions before bidding. It is one of the few lens filters made in East Germany at the time. There are also other lenses and lens hoods from that time. Please purchase these valuable items together. Depending on the bidding situation, we can also discuss discounts for bulk purchases. I would be happy to pass it on to someone who will cherish it. * Please feel free to ask questions. After winning the bid, no claims and no returns are accepted. * We will sell all the camera-related products currently on display as a set for 300,000 yen. If there are any items in the set that you don't need, you can resell them. Please feel free to comment on any product. Thank you for your consideration.
