Since I don't have a compatible camera, I haven't been able to check its operation. There is dust on the lens, but I don't think there's any mold that would affect the photos. A filter frame is attached, but I couldn't remove it because it was stuck. * Please note that this is a used item, and I don't have the specialized knowledge of a camera shop, so there may be oversights.
