Actually, when I went to change it, it appears I was right,
according to the dialogue on the menu screen.
On: "Enables ISO sensitivity from 100 to 12800"
Off: "ISO sensitivity can be set from 200 to 6400"
Curious, that.

Ah! I see. I thought by "expanded" it meant expanding the range
from 200-6400 to 100-12800.
In that case, I'll just turn off the expanded sensitivity, since I've
yet to encounter an instance where its use was particularly desirable.
Thanks!

HI all,
I've been meaning to ask this for some time now, but just keep
forgetting to. Anyway, here goes: From day one of ownership, I've had
the expanded sensitivity enabled on my K-x. I can force it manually
all
the way up to the 12800 top-end limit, but have yet to figure out a way
to get it to shoot at 100 -- not Shutter Priority, or any other. The
camera is clearly capable of shooting at that low a sensitivity, as
it's
indicated in the auto-ISO range (though I've yet to see a shot come out
of it with that indicated in the EXIF data.
So, what gives? I can't understand the rationale for allowing one to
force the camera all the way to the top end of its range, where IQ
suffers, but not at the bottom end, where one presumes it would
benefit.
Is there something I can do about this?
I believe you've answered your own question.
AFAIK, if you turn off expanded sensitivity you'll be able to use ISO
100.
