Olympus PEN E-PL5 vs Olympus PEN E-PM2: read noise comparison

Olympus PEN E-PL5DxO

The Olympus PEN E-PL5 was measured at 8 ISO settings from ISO 200 to ISO 25600. Values were derived by Bill Claff from DxOMark lab data.

At base ISO (200) read noise is 1.13 DN. From ISO 3200 up the camera is effectively ISO-invariant: raising ISO further doesn't meaningfully lower shadow noise.

Olympus PEN E-PM2DxO

The Olympus PEN E-PM2 was measured at 8 ISO settings from ISO 200 to ISO 25600. Values were derived by Bill Claff from DxOMark lab data.

At base ISO (200) read noise is 1.14 DN. From ISO 6400 up the camera is effectively ISO-invariant: raising ISO further doesn't meaningfully lower shadow noise.
