Lens works good. It shows normal wear on exterior. Filter rim in the front is bent, so it will not accept filters. But lens has drop in type rear filter holder. And it has rear UV filter installed. Please note that retractable lens hood is bent in the front as well, but it extends and collapses OK.
Lens focusing works, but it is noisy. I can hear grinding noise when I turn focus ring. That does not affect lenses performance, it focuses good, and ring is not tight. Front Glass does not have any visible scratches. I don't see any fungus or haze inside the glass. Glass is very clean and clear. Lens glass is very clean and very bright over all.
Focus works good. Aperture blades open and close properly. Lens looks and works good. I don't see any issues that would prevent it from working.
Lens comes with free and unconditional 90 day money back guaranty. So you have nothing to loose.
