Leica M-E Typ 220 vs Leica M10 MONOCHROM: 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 MONOCHROM

The Leica M10 MONOCHROM was measured at 29 ISO settings from ISO 160 to ISO 102400. Values are Bill Claff's (Photons to Photos) direct measurements from raw files.

At base ISO (160) read noise is 2.14 DN, or 6.1 electrons at the sensor. From ISO 1250 up the camera is effectively ISO-invariant: raising ISO further doesn't meaningfully lower shadow noise. Full well at base ISO is about 46,751 electrons; unity gain is around ISO 450.
