No doubt extremely good B&W imagery from a technical standpoint can be achieved from the Leica MM and also from color files from the M240 which although may not quite match the MM for DR or tonality, but apparently does a fine job. It's fairly well accepted that the color files from the M9 although good, are somewhat behind these two cameras. Personally I've worked with files from all three of these cameras and I would concur with this assessment.
I'm curious if anyone with a M240 or MM for that matte, closely compare B&W with their A7 or A7r against one or both of the Leica cameras? I'm extremely curious about this. Thanks!
