Sony has announced the a7R II, a 42.4MP mirrorless camera with a full frame BSI CMOS sensor. Unlike its predecessor, the camera includes on-sensor phase detection elements for faster autofocus. The camera also has a revised shutter mechanism, rated to 500,000 actuations but also promising less vibration than the one on its predecessor. The sensor is by far the largest backside illuminated CMOS chip to be released, allowing the maximum expanded ISO to rise two stops to 102,400. The camera will cost around $3,200.
