New Sony Sensor Will Bring Quick Tracking AF and 4K Video HDR to Smartphone Cameras

Sony isn't short on innovation. After exciting the photo industry last week with talk of a APCS (not to be confused with APS-C) sensor that promises to take dynamic range and especially frame rates to absurd heights, they've dropped another image sensor announcement.

The Exmor RS IMX230, announced earlier today, is being hailed as the first stacked CMOS image sensor with image plane phase detection, and it promises to bring super-fast tracking AF and better HDR to future smartphone cameras.
