For sale is this Yashinon 45mm f/1.7 lens with Leica M mount converted by a professional master (from a Yashica Electro 35). Unfortunately, the focus ring is detached and rotates, apart from that it is perfect. Minimal repairs are required, but my master has retired, he no longer undertakes repairs. Optically, it is in good condition, the aperture works fine, and the rangefinder coupling works. I attached a photo with it, on a M-P 240 body. Feel free to ask before buying.
