This is the rare S mount Nikon rangefinder 35mm lens.
The lens is in excellent condition and works perfectly. There are some very light cleaning marks on the front element, but I cannot see them without a flashlight, they will not affect your image quality. Otherwise the glass is clean and scratch-free with no haze or fungus. The focus and aperture are smooth. There is a small amount of oil on the aperture blades, but it does not affect their function. There is very light cosmetic wear.
The front cap is included.
