Regrettably rx1 returning.

Quite frankly, who cares.  Return it and buy what you want.  Your opinion is nothing but subjective.  I am not sure why all the posts of "I am returning......"

Guess what, I have an M9+50 Summilux and since I got my RX-1, I can unequivocally state, there is no comparison.  Not even in the same ballpark.  The M9 is up for sale and the only reason I am keeping the Summilux is to wait and see what the M10 brings, but quite frankly, I am already leery about the preliminary reports on the M10.
