I am newbie if its coming down to either of these relative new breeds of camera/system. Well, the old age is showing and I am considering getting a smallish camera that I can use in combination with my Leica M9 system to travel light. I like the idea of being able to use my Leica M lenses on it and at the same time being able to use AF using its respective lens. And the idea of bringing either one as a back up camera with possibly using AF on the long end is appealing to me. First, the basic question micro 4/3 or Sony NEX; what will be my best bet? If the first, which system does the typical user prefers; Panasonic or Olympus? While the first question seems to be fairly straight forward, I understand that the second question may bring up a ton debates. Can anyone enlighten me, please?
