How about this for trying out old lenses? I'm enjoying using it with a mirrorless camera or EOS SLR using a mount adapter. I'm selling it because I have another of the same model. K-mount is selected because there is no other option, but it is an M42 mount, so please prepare an M42 to mount conversion adapter for your camera. There is a large dent on the tip, but there is no damage to the lens itself. Dust and debris can be seen inside the lens, but I think it will not have a significant impact on shooting. Please consider this item if you understand that it is a junk item.
