Chinon MC 128mm F2.8 M42 mount. Picked this up as new (old) stock. I ended up not using the lens. It is absolutely in new condition, the only mark is a rub mark on the front lens caps. Includes original lens caps, built-in-hood, box, and instructions. The lens is spotless, focus ring tight and smooth. Solid lens. I have read good reviews of Chinon lens. This was a rare find for me but it needs to be used! Asking $75 or b/o + 10 USA shipped.
