Sony a380 read noise vs ISO
The Sony a380 (DSLR-A380) was measured at 6 ISO settings from ISO 100 to ISO 3200. Values were derived by Bill Claff from DxOMark lab data.
At base ISO (100) read noise is 1.44 DN. From ISO 100 up the camera is effectively ISO-invariant: raising ISO further doesn't meaningfully lower shadow noise.
