Panasonic Lumix DMC-LX3 vs Panasonic Lumix DMC-LX7: read noise comparison
Panasonic Lumix DMC-LX3DxO
The Panasonic Lumix DMC-LX3 was measured at 7 ISO settings from ISO 80 to ISO 3200. Values were derived by Bill Claff from DxOMark lab data.
At base ISO (80) read noise is 2.28 DN. Read noise keeps falling across the measured range, so the camera isn't fully ISO-invariant there.
Panasonic Lumix DMC-LX7DxO
The Panasonic Lumix DMC-LX7 was measured at 8 ISO settings from ISO 80 to ISO 6400. Values were derived by Bill Claff from DxOMark lab data.
At base ISO (80) read noise is 1.20 DN. From ISO 1600 up the camera is effectively ISO-invariant: raising ISO further doesn't meaningfully lower shadow noise.
