Leica M-E Typ 220 vs Leica M10: read noise comparison

Leica M-E Typ 220DxO

The Leica M-E Typ 220 was measured at 6 ISO settings from ISO 80 to ISO 2500. Values were derived by Bill Claff from DxOMark lab data.

At base ISO (80) read noise is 8.17 DN. From ISO 400 up the camera is effectively ISO-invariant: raising ISO further doesn't meaningfully lower shadow noise.

Leica M10

The Leica M10 was measured at 26 ISO settings from ISO 100 to ISO 51200. Values are Bill Claff's (Photons to Photos) direct measurements from raw files.

At base ISO (100) read noise is 1.99 DN, or 5 electrons at the sensor. From ISO 640 up the camera is effectively ISO-invariant: raising ISO further doesn't meaningfully lower shadow noise. Settings above ISO 20000 don't change analog gain (digital push). Full well at base ISO is about 41,004 electrons; unity gain is around ISO 500.
