I've moved it to what I assume is the correct forum, although I don't totally understand the question. Do you mean, what is the "native" ISO - the one the sensor actually operates at when no amplification is applied? I think the answer is 200, but maybe someone else knows better.

If you mean, how closely do the stated ISO values actually match ISO standards for exposure, dxomark publishes those results for each ISO level. Here are the Kx results, which show it being pretty true to ISO standards:

Kx

It's actually closer to ISO125 according to GordonBGood's testing at DPR.
