Kowa 135mm f/4 telephoto manual focus lens in the Kowa SER mount. Focus operates very smoothly throughout the entire range. Aperture blades are clean with no oil present and the aperture functions properly. The glass shows very light internal haze along with a few dust particles typical of age, but no obvious fungus or separation was observed. Cosmetic condition is very good overall with only light signs of normal handling and use. A nice example of this uncommon Kowa telephoto lens. Please see photos.
