If I read the graphs correct, the 5D mkII is never two stops better then
the 5D, I'd say mostly under 1 stop, in the 3200 region slightly over 1
stop. Actually, I'm quite surprised that in the iso range both cameras
share, the differences are not too big. The 5D mkII has a bigger range
of
ISO values though.
Best, Frank.
Just a quick caveat comparing noise. I recall with the 5D classic
the "native" ISO's were 100, 400, 800 .... The others were
interpolated with ISO 160 for example using 200 and
software adjusted-- with sometimes worse performance than a higher
"native" ISO. I quickly looked for the link I had posted a few years
ago with no success. The 5DII perhaps behaves a bit differently.
The better noise at ISO 160 may just reflect better ETTR though. DR at
ISO 50 suffers a bit and it is likely a "fake" ISO too.

PS I recall Moose always saying that he avoided the intermediate ISO's
and that is good practice.
