Sony ZV-E10 II read noise vs ISO

The Sony ZV-E10 II was measured at 34 ISO settings from ISO 50 to ISO 102400. This model has no measurement of its own; the Sony a6700 (ES), which uses the same sensor, is shown.

At base ISO (100) read noise is 1.57 DN, or 3.8 electrons at the sensor. A second gain (dual gain) kicks in at ISO 320, cutting input-referred read noise by about 1.2 stop. From ISO 1600 up the camera is effectively ISO-invariant: raising ISO further doesn't meaningfully lower shadow noise. Settings above ISO 12800 don't change analog gain (digital push). Full well at base ISO is about 38,767 electrons; unity gain is around ISO 240.
