I mean sony is more a niche market..for the Fujifilm, the made in Japan lens is good however their sensors for the X10 and X 20 is smaller than the 1 inch for the RX100. and I for the price, I prefer the RX100. For Sony have to buy their stand alone systems,,,if want to get it and than change lens etc,,can forget it...
Anyway, my shots are mostly indoor of family, parties etc...I dont need an ultra zoom, just one that is good with portraits and a bright lens...so I am leaning towards to Canon EOS M. It has most of what I want...
Unfortunately, the RX100 is too high end as a compact for most consumers. I don't see the point in making a full frame fixed lens compact that prices itself out of the consumer market. The winner will be Fujifilm.
