Nokia Lumia 1520 read noise vs ISO
The Nokia Lumia 1520 was measured at 7 ISO settings from ISO 100 to ISO 4000. Values were derived by Bill Claff from DxOMark lab data.
At base ISO (100) read noise is 1.29 DN. Read noise keeps falling across the measured range, so the camera isn't fully ISO-invariant there.
