I have been interested in Leica M camera for serveral years and I want to see a full frame Leica M digital camera. Most people would say that it can't be done under the current CCD sensor technology. But I want to do my own experiment to find out the possibility of a full frame Leica M camera. Now I have acquired a 24x36MM digital back, so I used it as the back end. First, I tried to use the Leica 35mm/1.4 Summilux as the lens. But found the lens end protruding too much. So I switched to Industar 55mm screw mount lens as the lesn for the testing of my prototype camera. I am so excited that I have got crystal clear pictures tonight! So my assumption is: a full frame sensor on M camera is technically possible, but it requires the redesign of some of the Leica M lenses. Also, for wide angle, maybe SLR type design will be needed to avoid dark corner vignett. But I think some people would be happy to sacrifice a little quality on the wide angle side, in return for a full frame Leica M camera. I will post some pictures here soon.
