I am thinking of buying a CL and using my M lenses. I understand that autofocus is inoperative but that does not worry me.. The question is - there appear to be a large number of adapters that can be bought so what is special about the Leica adaptor ? Are others as good ? Also one of my favourite lenses is my 40mm Summicron M. Can anyone kindly give me their opinion if they are using this lens on a CL ? any comments would be most welcome.
