The glasses are free from fungus and oil. The apertures open and close nicely. It comes with the B&W 49mm UV Filter. It also has a aftermarket metal lens hood. This is the Legendary Lens which is razor sharp wide open.
More importantly it is compact and unique and you need to use it and see it to appreciate. I have used this lens with both the Leica SL Full Mirrorless. I could only say it's worth every penny.
