Manufactured in 1975. I purchased this deadstock, unused lens on Mercari in 2024. It was disassembled and serviced, and I have been using it without any problems. There is no mold, fogging, or balsam separation. However, due to the old design, some dust particles are present, but they do not affect the photos. I am selling it because I am introducing new equipment, but it is a cost-effective lens that takes excellent photos. Good condition, late-model Jupiter 8 lenses are becoming rare, and I think this is a recommended item. This item has been in someone else's hands, so please understand that it is non-refundable and non-returnable to prevent any issues with product replacement.

Accessories: Adapter Front cap, rear cap UV protection filter (with case) Focal Length: 19-70mm Maximum Aperture: 1.5-2 Other Features: Old lens
