I purchased this item used. I am selling it because I am scaling back my photography activities. The rubber on the focus ring was missing from the start, so I used a substitute rubber band, but it did not cause any particular problems during use. (In fact, manual focusing was easier than with the original.) There is some fine dust inside the lens, but there is no dust or mold that would interfere with shooting. It is a light, compact, and easy-to-handle lens. Since it is an old item, I am selling it as junk (NCNR). Thank you.
