Sony's CMOS technology has exploded in the past two years, and has just "conveniently" unveiled a new black technology - the IMX197HSK sensor dedicated to ultra-high speed photography.

This 1-inch CMOS adopts Exmor RS and electronic full area shutter structure, which can achieve unlimited 8000FPS high-speed shooting (pistol bullets can already be shot) at full resolution.

The secret of its high-speed photography is its super photosensitive efficiency. By reducing the pixel density, it thins 80% of the backplane and uses pure copper wiring layers, Its pixel size goes to an exaggerated 9.78 µ m (while the iPhone boasting a large pixel size is 1.5 µ m).

Its photosensitive efficiency is more than 24 times higher than that of the IMX183 with the same 1-inch CMOS. Even at the highest 20480 ISO, its performance, except for color depth, is still far better than that of the IMX183 with the ISO800, which is 8 times higher than that of the A7s with the full frame 12MP CMOS.

However, the cost is also obvious. The total number of sensor pixels is 1.06 million (1442 × 742), and the effective pixels are 0.98 million (1368 × 722).
