Panasonic Lumix DC-ZS70 read noise vs ISO
The Panasonic Lumix DC-ZS70 was measured at 8 ISO settings from ISO 80 to ISO 6400. Values were derived by Bill Claff from DxOMark lab data.
At base ISO (80) read noise is 14.32 DN. From ISO 800 up the camera is effectively ISO-invariant: raising ISO further doesn't meaningfully lower shadow noise.
