Thank you for viewing. I am interested in old cameras and enjoy purchasing various used items, taking photos, and also repairing and maintaining them. This lens is a Minolta MD/MC mount, and it's a fun lens because it can still take quite beautiful images. Personally, I enjoyed using it with a mirrorless single-lens reflex camera using a mount adapter. The lens surfaces appear to be free of noticeable mold or fogging. There is a small spot of dirt on the back. However, I am not a professional when it comes to lenses, so I cannot perform a rigorous check. I would appreciate it if you could make a judgment based on the photos. Although the rear lens cap is missing, I will include a front cap, which may not be the original, but I will provide something. If anyone is interested, please feel free to inquire. I would like to make time to upload sample photos.
