Our RX1 samples album updated with high ISO images

I had the Sony A77 but was never happy with the high ISO results...after 1600 there were waaay too much noise when compared to the D800 or Fuji Xpro 1 which I use with auto ISO and never really have to think about that setting since it works so well with those cameras, but it looks like the RX1 is a whole different deal than the other sonys, and the high ISO examples are really terrific..not really sure why I would "need" another camera but it sure is something I would definitely like to use.  Maybe I need to rethink my equipment
