If you haven’t known already, the stacked CMOS sensor in the new Sony a9 flagship camera isn’t exactly all brand new. Indeed, it’s the first time Sony has done it with a full frame sensor and released it to the public. But the technology has been used in phones and many other sensors in the past. The Sony a9 has a full frame 35mm sized 24MP stacked CMOS sensor at the heart of the camera and the way it operates is crucial to the overall functionality of the camera.
We talked to Sony’s Mark Weir about how the sensor works and he explained how it differs from conventional CMOS sensors.

The new 24MP full frame sensor in the Sony a9 I feel was a great choice: there aren’t too many megapixels and there aren’t too few. Instead, it’s 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. Plus, the camera is very, very quiet. Sony is therefore targeting this camera to a number of photographers including photojournalists, sports shooters, etc. in the same way the company’s Sony a99 II is being delivered. However, the a99 II has much higher resolution and uses the company’s A mount system.
