Panasonic Lumix DMC-GH1 vs Panasonic Lumix DMC-GH3: read noise comparison
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.
Panasonic Lumix DMC-GH3DxO
The Panasonic Lumix DMC-GH3 was measured at 7 ISO settings from ISO 125 to ISO 6400. Values were derived by Bill Claff from DxOMark lab data.
At base ISO (125) read noise is 1.03 DN. From ISO 1600 up the camera is effectively ISO-invariant: raising ISO further doesn't meaningfully lower shadow noise.
