The rear camera will have a 23MP image sensor capable of 5x Clear Image Zoom (the latter was also seen in the Xperia M5). It will have the fastest autofocus in the market at 30 milliseconds (the Xperia M5 auto-focus was 250 milliseconds). Sony has optimised the software to provide better pictures. The Superior Auto mode will now let you select the resolution of your pictures to 8MP (16:9), 20MP (16:9) or 23MP (4:3).
