totally get you bruce, and totally agree with you. this is an art form and you need the tool that best expresses your vision. i was solely commenting on a pictures 'background' being too detailed and competing with the subject. thats not a matter of taste or sensor character, but of DOF control. a 35mm on a FF m9 will have the same oof area at a given aperture as will the FF rx1 at that aperture. it can certainly be that one prefers the m9's oof rendering to the rx1. but the oof area itself--ie the lack of detail therein, should be substantially similar. sorry if i misinterpreted your original comment
