However, through my tests the degradation is acceptable. See the sample on film. I can share more if you need. Under strong light, there are also slight cleaning marks (which typically don't affect imaging).But in general it has been professionally cleaned. Otherwise the lens is great. Comes with metal front and rear caps, which can be third-party but fits well. This item is in the category "Cameras & Photo\Lenses & Filters\Lenses".
