Panasonic Lumix DMC-FZ28DxO
The Panasonic Lumix DMC-FZ28 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 3.58 DN. A second gain (dual gain) kicks in at ISO 1600, cutting input-referred read noise by about 1.9 stop. Read noise keeps falling across the measured range, so the camera isn't fully ISO-invariant there.
