DJI Phantom 4 read noise vs ISO
The DJI Phantom 4 was measured at 4 ISO settings from ISO 100 to ISO 800. Values were derived by Bill Claff from DxOMark lab data.
At base ISO (100) read noise is 8.17 DN. From ISO 400 up the camera is effectively ISO-invariant: raising ISO further doesn't meaningfully lower shadow noise.
