Pixii A1571 vs Pixii Max: read noise comparison

Pixii A1571DxO

The Pixii A1571 was measured at 10 ISO settings from ISO 80 to ISO 25600. Values were derived by Bill Claff from DxOMark lab data.

At base ISO (80) read noise is 0.59 DN. From ISO 6400 up the camera is effectively ISO-invariant: raising ISO further doesn't meaningfully lower shadow noise.

Pixii MaxDxO

The Pixii Max was measured at 9 ISO settings from ISO 100 to ISO 25600. Values were derived by Bill Claff from DxOMark lab data.

At base ISO (100) read noise is 0.56 DN. From ISO 1600 up the camera is effectively ISO-invariant: raising ISO further doesn't meaningfully lower shadow noise.
