Samsung NX210 vs Samsung NX30: read noise comparison

Samsung NX210DxO

The Samsung NX210 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 0.97 DN. From ISO 6400 up the camera is effectively ISO-invariant: raising ISO further doesn't meaningfully lower shadow noise.

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.
