Nippon Kogaku Japan Nikkor-Q 135mm f/4 Bellows Lens

Rare bellows optic in excellent condition. So called "long mount" version with Nikon F mount. Optics are tidy, aperture adjusts evenly. 15 aperture blades. Nice cosmetics, just some light signs of use. Comes with a 43mm to 52mm step-up ring and Nikon lens caps.
