Olympus E-420 vs Olympus E-450: read noise comparison
Olympus E-420DxO
The Olympus E-420 was measured at 5 ISO settings from ISO 100 to ISO 1600. Values were derived by Bill Claff from DxOMark lab data.
At base ISO (100) read noise is 3.29 DN. From ISO 400 up the camera is effectively ISO-invariant: raising ISO further doesn't meaningfully lower shadow noise.
Olympus E-450DxO
The Olympus E-450 was measured at 5 ISO settings from ISO 100 to ISO 1600. Values were derived by Bill Claff from DxOMark lab data.
At base ISO (100) read noise is 3.23 DN. From ISO 400 up the camera is effectively ISO-invariant: raising ISO further doesn't meaningfully lower shadow noise.
