Yashica Auto Yashinon 75-230mm f4.5 M42 Screw Mount Telephoto Lens -Bargain-
This is a very nice metal built telephoto zoom lens for M42 screw mount. It would be an excellent addition to a classic m42 kit or adapted to mirrorless. Some of my first lenses on my mirrorless camera were adapted m42 lenses.
This one is in good condition with moderate wear. There are a few fine cleaning marks on the front element but they will not affect your image quality on a lens this long. Otherwise the glass is clean with no haze or fungus. The zoom and focus are smooth and the aperture is dry and snappy.
