The H2's mic pre's noise bed could very well be in that ballpark. I'm
just observing that it would be something if the self-noise of H2's
built-in mics' was that low. I assume one could use a portable
phantom power supply with its PIP mic input. Has hooked-up some low
noise mics to an H2?

It certainly wouldn't surprise anyone to find a compromised mic pre;
but you never know until its field tested. Rob D.
