Olympus PEN EPL1 vs Olympus PEN EPL2: read noise comparison

Olympus PEN EPL1DxO

The Olympus PEN EPL1 was measured at 5 ISO settings from ISO 200 to ISO 3200. Values were derived by Bill Claff from DxOMark lab data.

At base ISO (200) read noise is 4.72 DN. From ISO 800 up the camera is effectively ISO-invariant: raising ISO further doesn't meaningfully lower shadow noise.

Olympus PEN EPL2DxO

The Olympus PEN EPL2 was measured at 6 ISO settings from ISO 200 to ISO 6400. Values were derived by Bill Claff from DxOMark lab data.

At base ISO (200) read noise is 4.35 DN. From ISO 800 up the camera is effectively ISO-invariant: raising ISO further doesn't meaningfully lower shadow noise.
