Of course the Nikon D100 can cram more onto a card in RAW mode
because its CCD (or in this case Sony's CCD) doesn't produce as
much data. I think the Fuji SuperCCD simply produces more data
because of its pixel layout. There may not simply be a way to
throw out the data in a RAW format. After all, that's why it's a
RAW format. It's not like you can cut out a few bits of data and
make it perfect.
Or as I once saw in the movie "Amadeus"--
EMPEROR: Well, Herr Mozart! A good effort. Decidedly that. An
excellent effort! You've shown us something quite new today.
[Mozart bows frantically: he is over-excited.]
MOZART: It is new, it is, isn't it, Sire?
EMPEROR: Yes, indeed.
MOZART: So then you like it? You really like it, Your Majesty?
EMPEROR: Of course I do. It's very good. Of course now and then -
just now and then - it gets a touch elaborate.
MOZART: What do you mean, Sire?
EMPEROR: Well, I mean occasionally it seems to have, how shall one
say? [he stops in difficulty; turning to Orsini-Rosenberg] How
shall one say, Director?
ORSINI-ROSENBERG: Too many notes, Your Majesty?
EMPEROR: Exactly. Very well put. Too many notes.
MOZART: I don't understand. There are just as many notes, Majesty,
as are required. Neither more nor less.
EMPEROR: My dear fellow, there are in fact only so many notes the
ear can hear in the course of an evening. I think I'm right in
saying that, aren't I, Court Composer?
SALIERI: Yes! yes! er, on the whole, yes, Majesty.
MOZART: But this is absurd!
EMPEROR: My dear, young man, don't take it too hard. Your work is
ingenious. It's quality work. And there are simply too many notes,
that's all. Cut a few and it will be perfect.
MOZART: Which few did you have in mind, Majesty?
EMPEROR: Well. There it is.
p.s. me and mr davis was addressing the issue of the raw file size
of the s2 being 12 mb and hoping fuji would address this problem.
