well if you are going to use it, that would be a waste of my hard-earned money. since the OP asked what would i do, i will tell you. i'd buy neither. the mp is just too expensive for me as a hobbyist. moreover, a m3 user can be bought in great condition for way, way less; for me, as a hobbyist user, this 2750$ for a mint M3 is a mind-blowing waste of money that could be better spent on 3 ZM lenses. Or I would buy a user m3 and 2 ZM lenses.
