Olympus PEN EP2 vs Olympus PEN EP3: read noise comparison
Olympus PEN EP2DxO
The Olympus PEN EP2 was measured at 7 ISO settings from ISO 100 to ISO 6400. Values were derived by Bill Claff from DxOMark lab data.
At base ISO (100) read noise is 3.63 DN. From ISO 400 up the camera is effectively ISO-invariant: raising ISO further doesn't meaningfully lower shadow noise.
Olympus PEN EP3DxO
The Olympus PEN EP3 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 4.47 DN. Read noise keeps falling across the measured range, so the camera isn't fully ISO-invariant there.
