Samsung EX2F vs Samsung Galaxy NX: read noise comparison
Samsung EX2FDxO
The Samsung EX2F was measured at 7 ISO settings from ISO 80 to ISO 3200. Values were derived by Bill Claff from DxOMark lab data.
At base ISO (80) read noise is 1.48 DN. From ISO 100 up the camera is effectively ISO-invariant: raising ISO further doesn't meaningfully lower shadow noise.
Samsung Galaxy NXDxO
The Samsung Galaxy NX was measured at 9 ISO settings from ISO 100 to ISO 25600. Values were derived by Bill Claff from DxOMark lab data.
At base ISO (100) read noise is 1.21 DN. From ISO 3200 up the camera is effectively ISO-invariant: raising ISO further doesn't meaningfully lower shadow noise.
