Sony A7R3 camera: The menu is set to JPEG format L:40MB, why does it actually display 25MB?

In this case, there are roughly two possibilities.

1, 40MB does not refer to the file size, but refers to the pixel value. That is 40 million pixels.

2.40MB actually refers to the file size. However, due to the different shooting contents, the size of the photo file is not fixed. The file size may be smaller when shooting a relatively simple scene.

What is the specific situation? You must check the manual of the camera to see the specific meaning of that menu.
