    what do you think will be the maximum amount of MP's before image quality is
    so bad that consumers will quit buying?

  2. At the present time, the minimum acceptable size for a single pixel cell is
    about 2.7 microns on a side. (5 MP cameras with 1/1.8" sensors)
    The 2/3" sensor is about 6.6 x 8.8 mm.. If the pixel wells were 2.7 microns on a
    side, that would be 8 MP.

    A good point. It's all marketing hype.

    Serious user OTOH (i.e. people like me :) will be more discerning and
    investigate S/N ratio.

    What we need is a measurable, objective figure of merit that combines resolution
    and S/N. For that matter, just a published noise spec would be good.

    You mean like Dmax numbers for digital scanners? God help us.
    Offhand I can't think of any spec that is less standardized or
    objective. Manufacturers would play all kinds of games to avoid
    any meaningful comparisons.
