Panasonic Lumix DMC-FZ70 vs Panasonic Lumix DMC-G1: read noise comparison

Panasonic Lumix DMC-FZ70DxO

The Panasonic Lumix DMC-FZ70 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 2.75 DN. Read noise keeps falling across the measured range, so the camera isn't fully ISO-invariant there.

Panasonic Lumix DMC-G1DxO

The Panasonic Lumix DMC-G1 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 3.97 DN. From ISO 800 up the camera is effectively ISO-invariant: raising ISO further doesn't meaningfully lower shadow noise.
