Olympus XZ-1 vs Olympus XZ-2 iHS: read noise comparison
Olympus XZ-1DxO
The Olympus XZ-1 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 3.29 DN. Read noise keeps falling across the measured range, so the camera isn't fully ISO-invariant there.
Olympus XZ-2 iHSDxO
The Olympus XZ-2 iHS was measured at 8 ISO settings from ISO 100 to ISO 12800. Values were derived by Bill Claff from DxOMark lab data.
At base ISO (100) read noise is 1.74 DN. Read noise keeps falling across the measured range, so the camera isn't fully ISO-invariant there.
