Sony a350 vs Sony a37: read noise comparison
Sony a350DxO
The Sony a350 (DSLR-A350) 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 1.83 DN. From ISO 200 up the camera is effectively ISO-invariant: raising ISO further doesn't meaningfully lower shadow noise.
Sony a37DxO
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.
