Panasonic Lumix DC-GH6 (ES) vs Panasonic Lumix DC-GX800: read noise comparison

Panasonic Lumix DC-GH6 (ES)

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.

Panasonic Lumix DC-GX800DxO

The Panasonic Lumix DC-GX800 was measured at 9 ISO settings from ISO 100 to ISO 25600. Values were derived by Bill Claff from DxOMark lab data.

At base ISO (100) read noise is 0.47 DN. From ISO 6400 up the camera is effectively ISO-invariant: raising ISO further doesn't meaningfully lower shadow noise.
