Samsung NX1100 vs Samsung NX20: read noise comparison
Samsung NX1100DxO
The Samsung NX1100 was measured at 8 ISO settings from ISO 100 to ISO 12800. Values were derived by Bill Claff from DxOMark lab data.
At base ISO (100) read noise is 1.03 DN. From ISO 200 up the camera is effectively ISO-invariant: raising ISO further doesn't meaningfully lower shadow noise.
Samsung NX20DxO
The Samsung NX20 was measured at 8 ISO settings from ISO 100 to ISO 12800. Values were derived by Bill Claff from DxOMark lab data.
At base ISO (100) read noise is 0.74 DN. From ISO 200 up the camera is effectively ISO-invariant: raising ISO further doesn't meaningfully lower shadow noise.
