Olympus SP-565 UZ vs Olympus SP-570 UZ: read noise comparison

Olympus SP-565 UZDxO

The Olympus SP-565 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 4.11 DN. From ISO 800 up the camera is effectively ISO-invariant: raising ISO further doesn't meaningfully lower shadow noise.

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.
