Glass is clean and clear.No scratches, no fungus, no hazes. And no oil on blades. Cleaning marks on coating of lens, which does not affect the quality of the photos. I checked this lens with a camera SONY A7 Mark II. The images are sharp and quite a contrasting. The lens passed the service maintenance, therefore, the mechanisms for focus and aperture moves smoothly and freely. It is possible to have several dust particles inside the lens.
