Larger sensors do not have less low light noise. It is a myth. part 2

As long as the image circle of a lens is manufactured to fit the sensor, a large sensor does not produce less low light noise. Low light noise is determined by the amount of light hitting the sensor. The amount of light hitting the sensor is determined by the lens aperture in millimeters. Sensor size does not matter.

Full frame cameras produce less low light noise because they use lenses with a larger aperture, aperture as measured in millimeters.

However, larger sensor pixel size is good for dynamic range.

(Speed Booster has perhaps made it clearer to people that it is the lens, not the sensor that determines low light noise.)
