Olympus PEN EPM1 vs Olympus SP-565 UZ: read noise comparison
Olympus PEN EPM1DxO
The Olympus PEN EPM1 was measured at 7 ISO settings from ISO 200 to ISO 12800. Values were derived by Bill Claff from DxOMark lab data.
At base ISO (200) read noise is 4.00 DN. Read noise keeps falling across the measured range, so the camera isn't fully ISO-invariant there.
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.
