Panasonic Lumix DMC-FZ2500 vs Panasonic Lumix DMC-FZ330 read noise comparison

Panasonic Lumix DMC-FZ2500

The Panasonic Lumix DMC-FZ2500 was measured at 26 ISO settings from ISO 80 to ISO 25600. Values are Bill Claff's (Photons to Photos) direct measurements from raw files.

At base ISO (80) read noise is 0.54 DN, or 2.8 electrons at the sensor. From ISO 1250 up the camera is effectively ISO-invariant: raising ISO further doesn't meaningfully lower shadow noise. Settings above ISO 12800 don't change analog gain (digital push). Full well at base ISO is about 20,770 electrons; unity gain is around ISO 420.

Panasonic Lumix DMC-FZ330DxO

The Panasonic Lumix DMC-FZ330 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 2.03 DN. Read noise keeps falling across the measured range, so the camera isn't fully ISO-invariant there.
