If you're looking to be the king of Instagram, Sony's about to give you the ultimate smartphone weapon, judging by a leak from Xperia Blog. The site posted several purported images of the Sony ILCE-QX1, a lens camera system that'd work with interchangeable E-Mount style lenses. Sony's niche-oriented lens camera lineup is currently fixed-lens only with the QX10 and QX100 models. The QX100, for instance, is based on Sony's fantastic RX100 camera and priced for serious smartphone photographers at $500. Assuming the rumor pans out, the QX1 would have an even larger APS-C (26.7mm) sensor and take compatible E-Mount lenses. There are no other specs, but as before, we'd expect that your smartphone will control the QX1 and capture images from it, with a mount that adapts to a wide variety of handsets. It'll also likely have a built-in memory card. There's no pricing yet, but as a rule, interchangeable-lens cameras are usually more expensive than fixed-lens models. Then again, Sony tends to break that rule.
