D300 Sensitivity

Hi All,

could someone explain to me in SIMPLE terms, what Nikon mean when they
say the D300 has an ISO of 100ASA equivalent!

Is it really an ISO of 100, is it as good? Better?

Does it produce less / more noise?

Why don't they just say it has an ISO range of 100 - 3200?


Nikon Spec. D300
==============
Sensitivity
ISO 200 to 3200 in steps of 1/3, 1/2 or 1 EV with additional settings of
approx. 0.3, 0.5, 0.7 and 1 EV (ISO 100 equivalent) under ISO 200 and
approx. 0.3, 0.5, 0.7 and 1 EV (ISO 6400 equivalent) over ISO 320

It's some kind of pushed/faked low ISO and I can't imagine how they do
that: somehow throw out some of the charge??? It's supposed to be a
little less contrasty & less dynamic range but maybe even less noise
than the D200's ISO 100. More convenient than putting a neutral density
filter on I suppose if you need a longer exposure.

Either they turn it down after overexposing a stop (not practical
because of blown highlight problems though maybe for 1 stop those can be
recovered somewhat) or there is some way to filter the light coming in
which seems unlikely but that would work perfectly if possible.
