Alex,
Can I show you an APS-H version? Explain.
I think it would be a mistake for Pentax not to price the up-coming
10MP at a level just under the D200. At the moment I don't recall the
30D pricing.
IMHO, being late to that pricing segment of the market requires a bit
of catching up. Save the

Yes, in fact there's two different 10MP sensors available for 1.3x crop.
The first is used in the Leica Digital Module-R, and the second is a

Isn't the 9 micron larger than even the 5D?
Won't both color depth and exposure range benefit?

No, the 10MP Pentax will have an APS-C sensor

Yes to dynamic range. colour depth depends on the sensor design. But if
it's 1.3x and 10MP, there's a good chance its the same sensor as the
Digital Module-R, which is a 16bit sensor, not 12bit like the 6MP bodies.

As I understand it, won't the larger pixel size, also, tend to generate
less noise?

If the quality of the analog and digital electronics behind this

accordingly.
I wonder whether increasing the total dimension of the

Must say your math looks right. (actually 6.97 microns).
It's likely I buried Kodak's 9 micron reference to the 645D only to
have it surface when mulling the new 10D.
Yes, Canon stipulated that the 5D utilizes 8.2 micron pixels.

Shel,
Damned if I know!
I suppose it was a fragment of the 645D specs Kodak furnished, but
miss-filed in my 'cache'. Can't find it and the math actually looks as
though it may be limited to 7 microns. IOW, I agree with Patrice.
