[Top Mint] Nikon AI-S AIS Nikkor 20mm f/3.5 Ultra Wide MF Lens Nikon F Japan

Optics: Absolute perfection. I have inspected this unit under intense light to ensure the glass is crystal clear. There is NO fungus, NO haze, and NO scratches. The focus ring provides a silky smooth tactile experience, and the aperture is responsive and oil-free.
