DJI Zenmuse X4S read noise vs ISO
The DJI Zenmuse X4S 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 3.68 DN. Read noise keeps falling across the measured range, so the camera isn't fully ISO-invariant there.
