Samsung NX20 vs Samsung NX200: read noise comparison
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.
Samsung NX200DxO
The Samsung NX200 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 0.95 DN. Read noise keeps falling across the measured range, so the camera isn't fully ISO-invariant there.
