Re: fp Horizontal green lines with ISO 6?

I have no clue, just observing.

There are 14 sections divided by the green lines, which themselves appear to be 4 pixels high. From this horizontally compressed image, it's visible that they were created before the lens distortion correction:

Maybe you found some limitation of the readout circuitry, or maybe the camera chooses too long sub-exposures. It could worth contacting Sigma, maybe this information reaches the relevant engineer/programmer at Aizu…

BTW, what would've been the expected output? A perfectly white image (sans the darker smudge at the left)?  Does it happen when you try it in darker scenes or in complete darkness/keeping the lens cap on?
