Panasonic Lumix DC-GH6 (ES) read noise vs ISO
The Panasonic Lumix DC-GH6 (ES) was measured at 28 ISO settings from ISO 50 to ISO 25600. Values are Bill Claff's (Photons to Photos) direct measurements from raw files.
At base ISO (800) read noise is 18.90 DN. From ISO 1000 up the camera is effectively ISO-invariant: raising ISO further doesn't meaningfully lower shadow noise.
