This is The Real McCoy. Too bad the glass has marks:cry: (Beware, there are tons of fake LTM sonnars out there. They are cheapo russian copies. Some marked Jupiter, some put a silk-screen sonnar label on the front rim of the lens and priced at US$500. most do not RF-couple properly.)
BTW, the so-called modern cosina-made c-sonnar 1.5/50 ZM sucks lah. Since when a lens has to be optimised to focus properly at f2.8 or f1.5 ?! IIRC, someone reported at 1.5, the lens focus error is as much as 15cm!! How not to produce soft and creamy bokeh:bsmilie:
sorry OT. May the force be with the tock kong leica lenses!
