Sony a37 read noise vs ISO
The Sony a37 (SLT-A37) was measured at 9 ISO settings from ISO 100 to ISO 16000. Values were derived by Bill Claff from DxOMark lab data.
At base ISO (100) read noise is 0.72 DN. From ISO 800 up the camera is effectively ISO-invariant: raising ISO further doesn't meaningfully lower shadow noise.
