Although I agree that the new Olympus looks wonderful and is just the right size for a range of Leica and other rangefinder glass I am resistant to buying one due to the lack of a viewfinder. I am especially concerned about how to focus an M lens when holding the camera away from the body to see the rear LCD screen. Does this really work? Is it comfortable? Is it practical? I am asking because I want to know if its even worth considering for me.
