Leitz Canada Summicron-M 35mm f2 (Type 4) format_16mm Not just for astrophotography: thisThe classic 7 element Leitz 35mm f2 lens is sometimes called "King Of Bokeh" but we do not believe in absolute monarchies so I will refer to it as the "Democratically Elected Representative Of Bokeh" instead. It's just back from a complete CLA, with good focusing and diaphragm action; optics are clean and clear, with only minor dust. Cosmetic condition is excellent, with only very minor wear. One of Leica's smallest lenses, too. A really nice optic.
