Which P&S cameras have biggest CCD sensor?

    Do all consumer digital cameras use the same sized sensor? If not,
    does anyone know which brands or models offer the largest sensor
    available in a p&s camera? I would be interested to do a little
    research and find out if it made any difference to the image quality
    versus some competitors.

    Sensor sizes for P&S cameras are typically between 1/1.6" and 1/2.5". It
    does make a difference to the image quality (better dynamic range, less
    noise) although it's usually only noticable when using high ISOs.

    There are some fixed-lens cameras which use a big sensor (same size as
    entry-level DSLRs) but these are no simple P&S cameras because they're
    either very big (Sony R1) or extremely expensive (Sigma DP1).

    I would recommend evaluating image quality
    directly, rather than by proxy.

    Sony made or makes one with the same APS-sized sensor used in DSLR.
    The R1, if I recall correctly.

    the r1 is discontinued and the dp1 is vaporware with no official price,
    although it no doubt will not be competitive.

    That's probably not the right question. For example, when Panasonic
    replaced the FZ20 with the FZ30, they went from a 1/2.5" to a 1/1.8"
    sensor. Naively computing the size ratio, you might have expected the
    FZ30 to have about .72 the noise of the FZ20. In fact, the FZ30 appears
    to have just a tad more noise than the FZ20. Part of the reason is
    that the linear pixel density increased almost as much as the linear
    sensor dimensions in the FZ30. The area of each pixel is almost exactly
    the same in the two cameras.

    A better question than sensor size, or even pixel size, would be, "Who
    makes the lowest-noise P&S cameras?" Some of Fuji's designs stand out
    here, as I recall.
    It obviously makes a difference. Whether you think the difference is
    significant is up to you. Review sites like www.dpreview.com publish
    side-by-side comparison shots from competing models. Happy hunting.
