NX3000 Base ISO - 100 or 200 ?

Although ISO 100 is available as lowest ISO I doubt whether it is really the base ISO or whether ISO 100 is already a fake (like it is for example regarding my Olympus PL7), so that ISO 200 is really the base ISO. Does anybody know more about it?

"Fake" ISO values are usually available as JPEG only, here you have RAW as well.

If you want to really know, go to this link and contact Bill so you can do test photos yourself and he will add it to his collection of measurements http://www.photonstophotos.net/Charts/PDR.htm

Not really... 'Fake RAWs at ISO100' (when Base ISO=200) means that they are 1EV overexposed... which doesn't matter so much for RAW... but it's not a native/real ISO100  (valid e.g. for all Olympus MFT Cams)

Can anyone explain to me the pros/cons of shooting at base iso or below base iso?

No benefits, the camera over exposes by a stop and then tries to recover highlights.

I guess the only benefit is having ISO 100 for longer exposure (sunny and large aperture for example) on cameras with base ISO of 200 (m43, etc).

Everyone doing ISO tomfoolery seems to be using sensors less than APS-C size (admittedly anecdotal observation).  DXO measurements seem to indicate nothing strange for NX3000 (note, I do mean the measurement data, I'm not talking about the summary scores).
