XperiaBlog.net is reporting that official Sony Mobile accounts across social media channels today inadvertently published press pictures of the yet-unannounced flagship Xperia Z5 smartphone.

Sony itself teased earlier this week the unveiling of a smartphone "with greater focus," and that all would become clear on the 2nd of September. That date, of course, falls during IFA Berlin, the annual technology trade show where Sony will be present and has been known to unveil new hardware. The images seem to show the phone packing another one of Sony's Exmor RS pixel-stacked image sensors, although XperiaBlog.net states that the images confirm this one is a 23MP sensor — Sony doesn't publicly list a 1/2" 23MP sensor, so it would have to be one they haven't announced yet.

Aside from that, the images show the phone in gold, white and dark turquoise colors, as well as an "Xperia" logo engraved on one side, which we haven't seen on previous models. We predicted earlier this week that this new phone could come with Sony's hybrid autofocus technology, which Sony says combines two technologies — Phase detection AF for quick response and Contrast detection AF for added precision — to allow "fast, accurate focusing in all situations, even if your subject is moving." Sony's software is widely panned for softening up images and doing other things to negatively degrade them.
