>>3545235Let's use an equation the whole class can follow poppet.
Signal is the light gathered, noise is the variance from true. The more light gathered, the higher the signal. any ideas on how one could possibly gather more Light under an f2 lens? Could you maybe increase the area the light fell on to? Well done, you now understand why bigger sensor = better snr.
Sensor size doesn't form part of your equation though as it is already taken a given signal value. The signal value changes with sensor size.
Just read up the absolute basics of electrical engineering. Then you won't spend all this time making a fool of yourself.
