A friend has an M9. I have had M6 and now have a Zeiss Ikon ZM, which I find easier to use than a Leica, but the M9 was a puzzle. Heavy as hell and not particularly user friendly. Anybody ever do a comparison of quality of images between a full frame and m4/3? It would be interesting. I am NOT saying a $7000 camera is equal to a $700 camera, but for my friend, they probably are. But 16MP on a m4/3 and 18MP on the M9, obviously the pixels are larger on the M9, but it would be of interest to see what the comparisons look like.
