Panasonic Lumix DMC-GF6 read noise vs ISO
The Panasonic Lumix DMC-GF6 was measured at 9 ISO settings from ISO 160 to ISO 25600. Values were derived by Bill Claff from DxOMark lab data.
At base ISO (160) read noise is 3.61 DN. From ISO 6400 up the camera is effectively ISO-invariant: raising ISO further doesn't meaningfully lower shadow noise.
