Sony a330 vs Sony a350: read noise comparison
Sony a330DxO
The Sony a330 (DSLR-A330) 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 1.57 DN. From ISO 400 up the camera is effectively ISO-invariant: raising ISO further doesn't meaningfully lower shadow noise.
