Panasonic Lumix DMC-G3 vs Panasonic Lumix DMC-G5: read noise comparison

Panasonic Lumix DMC-G3DxO

The Panasonic Lumix DMC-G3 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 3.68 DN. From ISO 1600 up the camera is effectively ISO-invariant: raising ISO further doesn't meaningfully lower shadow noise.

Panasonic Lumix DMC-G5DxO

The Panasonic Lumix DMC-G5 was measured at 8 ISO settings from ISO 160 to ISO 12800. Values were derived by Bill Claff from DxOMark lab data.

At base ISO (160) read noise is 1.71 DN. From ISO 1600 up the camera is effectively ISO-invariant: raising ISO further doesn't meaningfully lower shadow noise.
