DxOmark (Click here) published the full Nikon A sensor test results. The Nikon beats all other tested High End Compact cameras. But it has to be said the the brand new X100s hasn't been tested yet. I guess the Fuji will outclass even the Nikon A.
The Coolpix A shipments just started at Amazon (Click here) and BHphoto (Click here). And the Fuji X100s is also shipping at Amazon (Click here).
