Interesting. So there's no gain on the imager and it's all just a matter of underexposure and multiplication during the development stage.

In that case then the ISO 50 with -1 compensation should be identical to ISO 100's normal exposure. Correct? Fairly easy to test.

Are the Quattro's ISO-less as well?

All of the Sigma cameras are.

Taking a break from my break - can't let that pass, sorry.

Some Sigma cameras are not ISO-less, i.e. they have AFEs.

your statement directly contradicts one already made by @maceoQ:

"Quattro, SD15, DP1x and DP2x are different, because they have an AFE (analog front end)"
