The only situation where things look bad

    As far as I can see, the only time I've seen digital
    images where things look "bad" is where you shoot
    things like tree limbs against a bright sky background.
    The lack of resolution (if they are far enough away)
    mixed with (?) seems to render them really ugly, messy,
    if you will. In fact, this is where digital seems to
    fall down when it is compared to film, at the point where
    resolution cannot match the details you are imaging.
    The only solution seems to be to print images such that
    the smallest thing you see is clearly resolved and the
    "mess" is below the level of the printer to print.
    For example;
    http://www.pbase.com/andersonrm/image/43590130

    This is a crop of a 100% 8 meg image, if printed would
    be 45" x 34." What is visible is on the edge of resolution.
    That, coupled with what I think is residual chromatic aberration
    has rendered the details "ugly." But, if you reduce the image
    size to the point where the branches are just resolved, the image
    looks good. From what I can tell, that would be at approximately 16"
    x 12." I think were the weakness of digital comes in is in the
    interaction of the sky background with the smallest tree branches.
    A sort of "bleeding" takes place that makes them poorly resolved.
    This kind of image degradation you do not see with (for instance)
    macro shots.

    .....snip and what does this have to do with dslrs? The Olympus C-8080WZ is
    not one.

    The problem effects them as well, especially since the 8080 lens
    has higher resolution than most DSLR kit lenses and it's
    sensor is 8 meg.

    For example;
    Yes, that's a highly realistic size for enlargement from an 8Mp image
    and going up close to check out the detail...... Sheesh.

    The example actually shows very good performance under those conditions
    - the 8080WZ is one of the best lens/sensor combinations for
    controlling the 'purple fringe' issue (that's why I bought one..!).
    See reviews all over the web to back that up. And you WOULD see the
    same problem in macro shots, if they had very strongly lit backgrounds
    and very thin dark detail in silhouette. But macro shots, just like
    portraits, very rarely look like that. Funny, isn't it...

    Lastly, it is, as pointed out by Ed, not a DSLR, and this is not a big
    deal with dslrs. But it's one more post for your statistics - Yaaay!!

    Which is why looking at 100% crops to determine "image quality" is silly at
    best, unless you are an engineer rather than a photographer.

    Unless of course you plan on making prints that large from an 8MP dSLR which
    IMHO isn't being realistic, you need at LEAST 6X7 medium format to go that
    large and really need a 4X5 LF camera.

    One of the negatives from a c8080WZ review:
    "Tough competition from D-SLRs; spend just a little more, get a much
    better camera (esp. in terms of photo quality)"
    http://www.dcresource.com/reviews/olympus/c8080wz-review/
    Of course they might be terribly wrong, and you might be incredibly right.

  8. Gee Stacey, I didn't know you felt that way.

    But then now that Olympus is burning off the old lines, you can
    buy it for around $525.00.
