    About the perfect digital camera...
    It does not exist yet.
    It should have adjustable image size,
    from 800x600 up to the longer dimension
    of 30x200 = 6000 pixels on the longer dimension.
    It should have ~20-40million tricolor pixels.
    It should be 24x36 mm sensor.
    It should shoot 4-5 frames per second.
    It should be able to output files of
    Raw, jpg, tiff, PNG
    It should have colocated color sensing.
    It should have good color fidelity.
    It should have good dynamic range.
    It should have a choice of body vendors.
    It should have a choice of lens vendors.

    A pro camera should work all of the time,
    not 'most of the time' on 'average' subjects.

    Problematical or silly conditional arguments:

    it does not work well on certain colored backgrounds,
    but they are not usual.

    It has 3 / 6 / 12 / 14 / 24 megapixels.

    The detail of a bayer filtered pixel element
    has as much value as if it were tricolor pixel.

    Foveon lack of filter:
    It has great detail and sharpness,
    but it produces artifacts at the pixel level,
    (On non random patterned subjects),
    and should be unsharpened / filtered.

    Bayer filter:
    It is filtered
    so it does not produce pixel level artifacts in repetitive patterns,
    (but the image has lost much detail
    in random patterned subjects.)

    On spatial filtering...
    It would seem
    that half the detail filtered out spatially is bad,
    and half the detail filtered out spatially is good.

    the choice of false small detail
    vs useful small detail has two sides.

    On Bayer clusters:

    If you can take a pixel that has only one color information,
    and generate information from surrounding pixels,
    then fuji S2 is really a true 12 mp camera.

    The Obvious:

    Most Bayer cameras do a pretty good job.
    Foveon can do a pretty good job.
    Both have limitations.

    And only cost £200 and have a battery duration of 20 hours.

    and a vertical / horizontal sensor.
    and run from aa nimh.

    It should be able to capture full-motion video with surround-sound,
    be able to take sharp, noise-free pictures in the dark without needing
    a flash, be no bigger than a credit card, never need batteries, have a
    built-in printer capable of producing 11x14 prints, and must cost no
    more than $80.

    now you made it a consumer toy.

    why not add 'wash dishes, mow the lawn, and babysit'?

    why would any rational person
    want to carry a printer on every job location?
