Sony showed off two camera units. One of them is a budget 8.1MP unit and the other is a 16.4 MP unit. Both can shoot full HD video.
The two sensors – IMX081PQ (16.4MP) and IMX105PQ (8.1MP) – use Sony's Exmor R technology. The 16.4MP module has a 1/2.8 back-illuminated CMOS image sensor with the smallest pixel size – 1.12 microns. The second module has a 1/3.2 sensor with pixels 1.4 microns in size. Both camera modules can shoot 720p and 1080p at 30 frames per second, while the 16.4MP sensor can do 720p at 60fps too.
