>>3986158>Shot noise will be sqrt(40) on both.That's not true. How can you really think this? One sensor is much more diluted than the other, and is taking a larger image. Let's go back to using this
>>3985335 as an example, where M43 is within the rectangle.
Say the M43 image has 40 photons. The FF image is the whole frame, it has 40 photons as well. So it only has 10 photons per quadrant, and is worse.
Get it? It's NOT just 'total photons' it's photons / unit area (le pickels)
