Olympus PEN E-P7 vs Olympus PEN E-PL7: read noise comparison

Input-referred read noise at base ISO: Olympus PEN E-P7 5.1 e⁻ (ISO 200), Olympus PEN E-PL7 6.1 e⁻ (ISO 200).

Olympus PEN E-P7

The Olympus PEN E-P7 was measured at 23 ISO settings from ISO 100 to ISO 25600. Values are Bill Claff's (Photons to Photos) direct measurements from raw files.

At base ISO (200) read noise is 0.82 DN, or 5.1 electrons at the sensor. From ISO 2000 up the camera is effectively ISO-invariant: raising ISO further doesn't meaningfully lower shadow noise. Full well at base ISO is about 23,899 electrons; unity gain is around ISO 1250.

Olympus PEN E-PL7

The Olympus PEN E-PL7 was measured at 23 ISO settings from ISO 100 to ISO 25600. Values are Bill Claff's (Photons to Photos) direct measurements from raw files.

At base ISO (200) read noise is 0.97 DN, or 6.1 electrons at the sensor. From ISO 800 up the camera is effectively ISO-invariant: raising ISO further doesn't meaningfully lower shadow noise. Settings above ISO 5000 don't change analog gain (digital push). Full well at base ISO is about 23,907 electrons; unity gain is around ISO 1250.
