Samsung NX30 vs Samsung NX300: read noise comparison
Samsung NX30DxO
The Samsung NX30 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 1.17 DN. From ISO 3200 up the camera is effectively ISO-invariant: raising ISO further doesn't meaningfully lower shadow noise.
