Bravo! Sigma and Foveon Get It Right!

  1. It's interesting to go back to the release of the SD9, before Sigma and
    Foveon attempted to re-define what a pixel actually is!

    Sigma Press Release
    ---------------------
    The breakthrough Sigma SD9 camera with Foveon(R) technology has the world's
    first image-sensor that features three layers of photodetectors. The layers
    are embedded in silicon to take advantage of the fact that red, green and
    blue light penetrate silicon to different depths allowing full-color to be
    measured at every pixel. The layers are positioned to take advantage of the
    fact that silicon absorbs different colors of light at different depths, so
    one layer records red, another layer records green and the other layer
    records blue. This means that for every pixel on a Foveon(R) X3TM image
    sensor, there's actually a stack of three photodetectors, forming the first
    and only full-color capture system.

    Foveon Press Release
    ----------------------
    The Foveon X3 image sensor in the Sigma SD9 contains over 10.2 million color
    photodetectors, which are organized in 3 layers within the sensor to form
    3.54 million full-color pixels. By dedicating three color photodetectors for
    each pixel, the SD9 produces images that are sharper, have better color
    detail and are more immune to color artifacts than currently available six
    megapixel digital SLR cameras. The Foveon X3 image sensor is the world's
    first full-color image sensor that captures red, green and blue light at
    every pixel in a single exposure. The Foveon X3 technology breakthrough is
    accomplished by embedding three photodetectors in silicon at each pixel.

    -------------------------------------------------------

    Wow, look at that!

    Sigma says: "...for every pixel on a Foveon(R) X3TM image sensor, there's
    actually a stack of three photodetectors...
    Foveon says: "The Foveon X3 technology breakthrough is accomplished by
    embedding three photodetectors in silicon at each pixel."

    I don't know when the marketing people went crazy.

  2. Maybe when their fine 3.4 Mpixel sensor not sold good enough?
    And when the funders did not want to put in more money?
    And they went deperate?

  3. Nonsense. The "funders", as you put it, have not stopped putting in
    more money. On the contrary, they have increased their investments
    across the board. The next generation Foveon sensor is going to be out
    of this world. If I were you, I would start buying put-options on
    Canon stock, as it is about to hit the floor once the next-gen Fov
    sensor announcement shows up on DPReview.

    Hope this helps.

    Oh George, you're so silly. You know that won't happen at all.

  6. Orville Wright is: The person posting under the name of George or
    Georgette Preddy (and other pseudonyms) has an ungrounded but zealous
    faith that current implementation of the Foveon chip is superior to all
    other chip technologies. He will cite portions of reviews to ostensibly
    support his claims, and will repeat, ad naseum, complete lines of
    out-of-context material, as well as manufacturing some pure bull manure.

    Moreover, "Mr." "Preddy" has claimed to be a photographer (pro!), but
    cannot bring himself to post a single picture with EXIF info that he
    shot himself, in spite of repeated requests and challenges to do so.

    Apparently he loathes anything related to Canon and loves everything
    about Sigma cameras and lenses. His "claims" may be ignored, and he is
    doing Sigma, and anyone related to the Foveon chip, no good at all by
    arousing ire, increasing the N/S ratio, and generally spamming this
    newsgroup.
