Canon PowerShot G9 X Mark II vs Canon PowerShot S110: read noise comparison

Canon PowerShot G9 X Mark IIDxO

The Canon PowerShot G9 X Mark II was measured at 8 ISO settings from ISO 125 to ISO 12800. Values were derived by Bill Claff from DxOMark lab data.

At base ISO (125) read noise is 4.17 DN. From ISO 3200 up the camera is effectively ISO-invariant: raising ISO further doesn't meaningfully lower shadow noise.

Canon PowerShot S110DxO

The Canon PowerShot S110 was measured at 8 ISO settings from ISO 80 to ISO 6400. Values were derived by Bill Claff from DxOMark lab data.

At base ISO (80) read noise is 2.07 DN. From ISO 3200 up the camera is effectively ISO-invariant: raising ISO further doesn't meaningfully lower shadow noise.
