Panasonic Lumix DMC-GF3 vs Panasonic Lumix DMC-GF6: read noise comparison

Panasonic Lumix DMC-GF3DxO

The Panasonic Lumix DMC-GF3 was measured at 7 ISO settings from ISO 160 to ISO 6400. Values were derived by Bill Claff from DxOMark lab data.

At base ISO (160) read noise is 4.50 DN. From ISO 400 up the camera is effectively ISO-invariant: raising ISO further doesn't meaningfully lower shadow noise.

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.
