Further encroaching on the camera space, Sony has just released a new “stacked CMOS sensor” that will reportedly place an effective 21 megapixels into a 1/2.4-inch-sized form factor. The Exmor RS IMX230 comes with a built-in 192-point phase detection autofocus, which means it can keep fast-moving objects sharp, as well as HDR and 4K video. This new sensor will debut in April 2015 and will most likely be seen in Sony’s new flagship.
