Hasselblad H3DII-39 read noise vs ISO
The Hasselblad H3DII-39 was measured at 4 ISO settings from ISO 50 to ISO 400. Values were derived by Bill Claff from DxOMark lab data.
At base ISO (50) read noise is 23.92 DN. From ISO 50 up the camera is effectively ISO-invariant: raising ISO further doesn't meaningfully lower shadow noise.
