Olympus PEN EPL2 vs Olympus PEN EPL3: read noise comparison

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.

Olympus PEN EPL3DxO

The Olympus PEN EPL3 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 4.08 DN. From ISO 400 up the camera is effectively ISO-invariant: raising ISO further doesn't meaningfully lower shadow noise.
