Panasonic Lumix DC-G90 vs Panasonic Lumix DC-GH6: read noise comparison

Input-referred read noise at base ISO: Panasonic Lumix DC-G90 3.8 e⁻ (ISO 200), Panasonic Lumix DC-GH6 1.1 e⁻ (ISO 800).

Panasonic Lumix DC-G90

The Panasonic Lumix DC-G90 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 0.91 DN, or 3.8 electrons at the sensor. From ISO 1600 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 16,371 electrons; unity gain is around ISO 830.

Panasonic Lumix DC-GH6

The Panasonic Lumix DC-GH6 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 (800) read noise is 18.90 DN, or 1.1 electrons at the sensor. From ISO 1000 up the camera is effectively ISO-invariant: raising ISO further doesn't meaningfully lower shadow noise. Full well at base ISO is about 3,678 electrons; unity gain is around ISO 50.
