This is a single Canon lens. It's quite old, but I've kept it carefully. It was one of my father's collection, but I'm selling it because he no longer uses it. As far as I, a camera novice, can see, there don't seem to be any major scratches or clouding on the lens. I don't know much about cameras or lenses, so I can't provide detailed information. Please make your judgment based on the images. Please consider this item as a long-term storage item and an old item. Thank you for your consideration.
