    Just for the heck of it...
    ....I had a buddy enter an image taken with his Canon 10D DSLR with a 50mm
    prime lens. Incredible. The MTF was 62.49, almost 3 times that of the
    highest rated scanner, and the pixel rise was 1.04. This tells us that using
    a slide taken with a camera and lens certainly lacks the sharpness needed to
    help differentiate the higher-end scanners, as I suspect the superior optics
    can define sharper lines than my target image. Although, coming up with a
    slide image *that* sharp would be a challenge... which brings us back to the
    "street-level" results I was looking for in the first place. Something to
    chew on. Here's a link to the actual results.

  2. No, it tells us that the scans were not sharpened (as instructed), and
    the 10D image was sharpened (because the AA-filter prohibits a pixel
    rise of 1.04).
