    What he also said was that you would not see the difference unless you
    printed at A3 size, FFS just how many print at A3 size from jpegs, it was a
    stupid coment that just made him look like someone that had not read the
    manual that clearly states that the standard jped settings are purposely not
    sharpened much to preserve deetail and that if you want razor sharp jpegs
    from the camera to adjust the settings.

    Here is a shot I took a week or two back at standard default settings, looks
    plenty sharp to me. This is about 2Mb straight from the camera, yes I know
    it is overexposed in one or two spots.

  2. Thanks for the photo, Pete. Yes, it looks sharp enough to me (although
    the small amount of movement in the images makes that judgment less
    certain), but I can imagine that if printed or when reduced for the Web a
    small amount of extra sharpening might help. Depending on your taste and
    the subject, of course.

    I also prefer edges rendered without any artificial overshoot which
    results from too much sharpening. To me, when "razor sharp" is mentioned,
    I immediately think: "Oh, dear!".

    I don't think that DP Review do this, but allowing users to add comments
    like yours to the review might make them even more useful for potential
    purchasers. I mean at the end of the review, not in the discussion
    forums.

    Cheers,
    David

    I really do think that most of their reviews are pretty straight down the
    line but there has been a few that were questionable. I will also say that
    their comparison tool is very good for doing a feature for feature
    comparison at least for the cameras that have the info correct.

  4. Opinions of individuals vary - a review is NOT a test report!

    Usually the opinions are at the end of the test(s)
    as opinions. A review should list stated facts, not opinions.
    This is in the scientific/engineering world not movies or literature.

  6. Where the opinions are expressed in a review is irrelevant. Whilst a
    review certainly can include specific tests, it is NOT limited to that -
    it contains subjective assessment and opinions.

    This really is a simple argument. TrollA claims a review is just a
    series of standard tests but if that was the case then only test ERROR
    would cause any difference between reviews. Reviews exist which differ
    without errors in the tests therefore, the original claim must be false
    - proven by contradiction. Just as his claim that Olympus were reacting
    to a pro-Canon bias at DPR was easily proven by citing just one example
    of the same response, and more, by Canon. Presumably Canon were
    reacting to a pro-Canon bias at DPR too.

    Nobody has yet cited an instance in this thread where DPR have
    undertaken a test which is pro-Canon biased - they are citing opinions
    and subjective assessment which MAY be. It is opinions and assessment
    which cause reviews to differ - the standard tests give consistent
    results but are frequently open to different interpretation.

    One reviewer might think that the greater weight of camera A over camera
    B to disadvantage A - it sure is if you are lugging lots of kit around
    in your backpack - while another considers it to advantage A, since it
    has greater inertia and hence lower hand-holdable shutter speeds. In
    either case, each reviewer has the same test data (measured mass), one
    may be pro-Canon the other pro-Olympus, but they are both perfectly
    valid reviews.

    If you want basic test data without assessment or opinion then, as
    indicated in the name of the site, DPReview is not for you. There are
    plenty of test sites around.

  7. Since I have my K10D, I was forced to stop shooting jpg. The jpg engine is
    one of the worst I have seen on this camera.

    And Phil is not the only one to say that about that problem btw. Even Pentax
    users are shooting RAW.

    Interesting summation. Where are the 'plenty of test sites'?
    A link would be appreciated.

  9. you cant denied this:
    Image sharpness / demosaicing (JPEG vs. RAW)
    "We were a little disappointed that the K10D's built-in image processor
    didn't deliver the crisp sharp edges which can be produced by shooting RAW
    and converting using a third party engine (such as Adobe Camera RAW). It's
    speculation but it does appear to me to be a combination of the type of
    demosaicing algorithm used (not isolating edge detail well enough) and the
    type of sharpening algorithm (as discussed earlier this appears to work to
    enhance the 'undershoot', the black side, of an edge). As we saw in the
    Image Parameters section of this review increasing sharpening only appears
    to increase the visibility of texture type detail rather than edge
    sharpness.

    Below you can see a comparison using our standard studio scene between JPEG
    straight from the camera and a RAW converted using Adobe Camera RAW (as per
    our normal RAW converter settings, no sharpening and then a 80% unsharp mask
    applied after conversion). "

    Just look at the samples below that text !!!!

    http://www.dpreview.com/reviews/PentaxK10D/page16.asp

    Anyway, Im shooting RAW and Im very happy now. Great IQ, probably the best
    you can get from that sensor (D80, Alpha , K10D).

    Of course I need to use CS2, but guess what, I like it now, I cant explain
    why, but I have fun PP all my pictures. (I never would believe this a few
    months ago).

    You really are joking, aren't you Slack?
    Asking Peter Dee to substantiate anything he says is like expecting DP
    review to be truthful in their reviews... NOT going to happen!
