Panasonic Lumix DC-GH6 vs Panasonic Lumix DC-GH6 (ES): read noise comparison

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.
