As you all know I am Brand Ambassador for Light Lens Lans, TTArtisan and 
7/Artisans (and Candido Film among others) by nature i have to have main 
platforms to test (yes 240 and M10p are same sensor but we do cine lenses 
and M240 has video primitive but good for testing) Mo need for 272 D 
variants or p non p.  When all is said and done i prefer images kronquistm 
instagram from my M9 to even my M11.  Yes res is higher and ccd low iso and 
no live view pia but almost always i put a new lens on my M9-p for first go 
shots.  Replacement sensor with original type.  Ditto my Monochrome. Someday 
both will need new glass and Kolari  my two cents fix m9
