    This look like it will be a good one???

    Not yet in UK but anyone elsewhere got one or know the price range?

  2. Only 7 megapixels - that is a let down. Should be at least 8,
    perhaps 10 or even 12.

    I might agree with 8 mp, but cramming 12 mp on a tiny sensor the size of the
    one on that camera would probably result in some quality issues. I think
    Oly is to be applauded for not getting into the megapixel race, but rather
    keeping the resolution proportionate to the sensor size and sacrificing
    "throw weight" for image quality.

    My needs are for a camera with wide angle (28mm) which I have with my
    Olympus 5060 but missing a better zoom when I need to get further back! So
    will keep an eye on it as the 7 megapixels is fine for my needs.

  5. 5 or 6MP would be a better match for the sensor size.

  6. The Canon A640 does 10mp on its sensor. Is that not a good match
    Paul D. Sullivan, Jan 26, 2007
  7. I suspect that for the great majority of uses, a 5MP or 6MP sensor would
    be a better compromise there as well. Of course, if your are regularly
    printing at greater than A4 size (210 x 297mm) you may prefer more pixels.

    Note that Nikon in its most recent DSLR has opted for a quality 6MP sensor
    rather than following the marketing droids "more MP is better".

    If 7mp is too many pixels for the SP-550's 1/2.5" sensor, then 10mp
    is also too many for the A640's larger 1/1.8" sensor. The A640
    doesn't cram the pixels quite as tightly, but it's pretty close,
    with less than a 10% difference. If you want to work it out for
    yourself, dpreview gives these dimensions for the sensors, including
    for comparison APS-C, which is roughly comparable to the size of
    most DSLR sensors:
    Comparing the 10mp A640 with the 7mp A620, the increased number of
    pixels doesn't translate to the same increase in resolution. The
    horizontal and vertical absolute resolution increased from 1,550 and
    1,600 LPH to 1,775 and 1,850 LPH. This is very close to what you'd
    expect from an increase of 7mp to 8mp. If the A640's resolution
    increased in proportion to its 10 mp, it would have achieved 2,214
    (hor) and 2,286 (vert) LPH. Along with its very modest improvement
    over the A620, the A640 is probably a bit noisier at the high ISOs.

    (see http://www.dpreview.com/reviews/canona640/page15.asp )

    How does my old Fuji S5100 with its small 1/2.5" 4mp compare?
    According to dpreview, absolute resolution is 1,200 and 1,250 LPH.
    Not too bad, and the diminishing returns gotten from the higher mp
    count sensors is apparent. If the S5100's sensor was enlarged in
    its physical dimensions to provide an increase from 4mp to 7mp and
    10mp (assuming a perfect lens to match), its resolution would
    increase to 2,100 and 2,188 LPH (7mp) and 3,000 and 3,125 LPH
    (10mp). The A620 (which I also own) and the A640 don't come close
    to matching these resolutions. In other words, as most people here
    have long recognized, the megapixel race is mainly a numbers game
    devised by the camera manufacturers' marketing departments. It
    helps sell cameras, but doesn't help make good purchasing decisions.

    I'll take a look at it but in my work I haven't time to change lenses.

    Now if they'd scrap the stupid xd cards and get with the rest of the world.

    I guess it's no problem at all if you don't mind paying twice as much for
    every card you get - I do.

    I recently bought a Kodak P850 refurb from the kodak online store. 12x
    zoom, IS, only 5.1mp, SD card, and 237k EVF - much better than the 110k
    EVF on most competing brands. I'm quite pleased with it.
    ray, Jan 27, 2007
  13. Sounds great. I hope you are very happy with it.

    Is Kodak a good quality Digital Camera? I had been thinking top
    tier like Nikon, Olympus, etc. and had not considered Kodak in
    terms of cameras. Do they compare well?
    Paul D. Sullivan, Jan 27, 2007
  14. Except there is no image stabalization in the E-400, and you have to change

    YMMV - we've had two Kodak digital cameras, one Nikon and one Minolta. I
    don't find a lot of fault with any of them. I think they are fine, some
    folks seem to have a problem.

  16. No need to be so pessimistic.

    No need to be so polite. That was not a pessimistic statement.
    It was an intentionally and Richly ignorant, stupid statement.

    Just trying to be civil. :)

    There's three samples (wide, medium, and real tight here... about a
    third way down the page. Hover your mouse over the description under
    the picture.


    Take care.

    Good policy in general, but not if it also attracts the wrong
    types. You should be daubing yourself not with honey but with
    Troll-Begone. It's non-greasy and is available over-the-counter in
    2 oz. and 5 oz. squeeze tubes. :)
