The CCD size limitations are similar to those in the production of LCD
panels, and the max production size of those been increasing
continuously over time. I expect the same will happen to CCDs,
eventually making 35mm-sized CCDs a reality.
>From my understanding of CCDs (which may have holes :), the size of the
CCD affects only resolution, not light-sensitivity. As far as the
light-sensitivity of current consumer digital cameras, I've only seen
cameras with ISO equivs of about 200 and less... I don't know if this
will increase with time.
One thing I have wondered about in relation to CCDs is the fact the
apparently lack of slow shutter speeds on consumer digital cameras. I
haven't seen one yet that goes slower than 1/3-1/4 sec. Is this a
limitation of the CCD, kind of like an extreme version of reciprocity
breakdown in film? Or are these slow shutter speeds available on high
end digital cameras, and left off consumer cameras since they figure you
don't need them?
As far as the OM comment goes, I suspect they don't (didn't?) plan on
thier cameras being in use as long as they have. Another piece of
evidence that contributes to this is that thier databacks apparently
have a Y2.01k problem (2010).

Subject: [OM]New question OM-5 digital
Another question,
there was recently an discusion about this new digital-film for every
camera. In this dicusion somebody claimed, that the equivalent
sensibility of todays CCDs is around 100-400 ASA and in order to raise
the sensitivity they had only the posibilty to make the CCD cells
biger. The propblem is now, that makeing CCD arays biger, will increase
there price unproportional, because of the difficulty to produce big
flawless dies (this should be the name of the small silicone pieces).
If this is true, we will never see CCDs, which could compete with
classical silver halogen film.
Which leads me to another question: If read, that the theoretical
maximum sensitivity of film will be around ISO 819200/60°.
Can somebody (Kennedy?) confirm this?
OM content: The Olympus enginers were not to optimistic when they
designed the OM cameras ASA dial, eiter with the lifespan of the camera
bodys or with the abilitys of film producers.
