Very clear glass, no fog, no fungus, no separation, not even much dust as any lens that changes its internal volume when focusing will have. Aperture blades are free of oil and work as they should, focus smooth. Lens is ready to use. Cosmetically nice as you can see.
Note vintage lenses don't always work well when adapted to digital cameras...no way to know until you try it. Check the reviews if that's your interest.
Also note when using a lens with an aftermarket adapter it is common for the lens to focus past infinity...this is the condition of the adapter, NOT the lens. Safer to have the lens focus just past infinity vs not reaching infinity. The distance labels on the focusing ring will no longer be perfectly accurate.
