Well what do we have here? Looks like Sony’s new QX1 lens-style camera with E-Mount attachment. The QX1 will use the Exmor APC-S sensor judging by the pics. The pictures also confirm some kind of pop-up flash.
The press photos also show the first official picture we have seen of the Xperia Z3. We mostly get to see pictures of the rear of the handset.
Update: SAR has a whole gallery of photos for the ILCE-QX1 lens-style camera.
