The lens comes with an original Nippon Kogaku front cap.
* The lens barrel is clean and beautiful.
* There is no oil on aperture blades.
* The glass is beautiful too, clean and scratch free.
* There is no fungus.
* There is no haze.
* There are no cleaning marks.
* I have used this lens successfully with my Leica M cameras thanks to Amedeo Nikon S to Leica M adapter (not included in this sale!).
