How the Stacked CMOS Sensor works in the Sony a9
The stacked CMOS sensor in the new Sony a9 flagship camera is not exactly all brand new, it is the first time Sony has done it with a full frame sensor and released it to the public. Before the technology has been used in phones and many other sensors in the past.
The new 24MP full frame sensor in the Sony a9 is a great choice: there are not too many megapixels and there aren’t too few. Instead, it is designed to give you pretty good resolution, high ISO results, and also designed to shoot a ton of frames per second as you need them.
