or maybe narrower domain. ISO 200 or less.

The shots you showed are showing resized down. The ones that are low iso will do well (not that many cameras wouldn't do a reasonable good job that can compare with these images too). The ISO 800 as we discussed before it's something that I believe I even mentioned a Pentax Q would come close at that size. I even posted you the examples, I don't remember hearing back.

So you have shots at ISO 800 or less where ISO 800 doesn't look all that good. And we aren't getting into the color constancy issues- which you easily get by ISO 400, often at ISO 200 - and if we are going to talk about "ultimate image quality" and comparing with other cameras- yes, they have to be mentioned.

The shots you showed do not show much special, honestly.

But to be fair, I should say the narrower domain. You can certainly do a lot at ISO 100.
