DJI Phantom 4 vs DJI Zenmuse X4S: read noise comparison
DJI Phantom 4DxO
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.
DJI Zenmuse X4SDxO
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.
