Panasonic Lumix G9 II vs Panasonic Lumix GH5 II: read noise comparison

Input-referred read noise at base ISO: Panasonic Lumix G9 II 2.5 e⁻ (ISO 100), Panasonic Lumix GH5 II 3.8 e⁻ (ISO 200).

Panasonic Lumix G9 II

The Panasonic Lumix G9 II (Lumix DC-G9M2) was measured at 28 ISO settings from ISO 50 to ISO 25600. Values are Bill Claff's (Photons to Photos) direct measurements from raw files.

At base ISO (100) read noise is 9.78 DN, or 2.5 electrons at the sensor. From ISO 3200 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 16,380 electrons; unity gain is around ISO 30.

Panasonic Lumix GH5 II

The Panasonic Lumix GH5 II (Lumix DC-GH5M2) was measured at 25 ISO settings from ISO 100 to ISO 25600. Values are Bill Claff's (Photons to Photos) direct measurements from raw files.

At base ISO (200) read noise is 0.68 DN, or 3.8 electrons at the sensor. From ISO 2500 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 22,046 electrons; unity gain is around ISO 1110.
