Panasonic Lumix DMC-GF6 vs Panasonic Lumix DMC-GH1: read noise comparison

Panasonic Lumix DMC-GF6DxO

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.

Panasonic Lumix DMC-GH1DxO

The Panasonic Lumix DMC-GH1 was measured at 6 ISO settings from ISO 100 to ISO 3200. Values were derived by Bill Claff from DxOMark lab data.

At base ISO (100) read noise is 1.48 DN. From ISO 400 up the camera is effectively ISO-invariant: raising ISO further doesn't meaningfully lower shadow noise.
