I have an M6 MK II and that camera is not lacking in resolution that is for sure. Weather sealing... Now that can be improved.For APSC 32 MP (as seen in the M6-II is actually not stingy. You'd need an 82 MP (roughly) full frame to hit that pixel density, and few of those are out there. To get 45 MP which you consider non-stingy would be the equivalent of a 115 MP full frame. Admittedly I don't follow other brands (so someone please correct me if I am wrong), but I don't think such a thing exists yet.
