Olympus SP-570 UZDxO
The Olympus SP-570 UZ was measured at 6 ISO settings from ISO 64 to ISO 1600. Values were derived by Bill Claff from DxOMark lab data.
At base ISO (64) read noise is 4.41 DN. From ISO 64 up the camera is effectively ISO-invariant: raising ISO further doesn't meaningfully lower shadow noise.
Olympus Stylus 1DxO
The Olympus Stylus 1 was measured at 8 ISO settings from ISO 100 to ISO 12800. Values were derived by Bill Claff from DxOMark lab data.
At base ISO (100) read noise is 1.37 DN. From ISO 3200 up the camera is effectively ISO-invariant: raising ISO further doesn't meaningfully lower shadow noise.
