Panasonic Lumix DMC-G10 vs Panasonic Lumix DMC-G3: read noise comparison

Panasonic Lumix DMC-G10DxO

The Panasonic Lumix DMC-G10 was measured at 7 ISO settings from ISO 100 to ISO 6400. Values were derived by Bill Claff from DxOMark lab data.

At base ISO (100) read noise is 4.35 DN. Read noise keeps falling across the measured range, so the camera isn't fully ISO-invariant there.

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.
