Well, to my surprise, the FINE SHARPNESS feature, explained in page 155 (item 5) of the manual, when activated, indeed produces a bit sharper images, but with unacceptable noise levels.
See the results:..
No doubt the "chain" looks sharper on the left image, but the noise level at the smooth wall paint is a lot higher. Also note the "edge" (left in diagonal). On the left shows like a highlight that "pretends" to render a sharper image, but in reality, such highlighted edge does not exist (see right image)
Anyone has noticed such?

Hi,
Your information given were too limited for people to study. Please let us know more information such as the focal length, settting of the lens, the Aperature (F/?) and the exposure time etc.
First feeling is that when you apply the "sharpeness on", then you have got JPEG artifact. (you can get rid of this by taking RAW)
I suspect what K20d did for you were:
Sharpeness ON: The amount degree of noise reduction was reduced (to retain more details) + edge sharpening process was applied on that picture .
Sharpeness OFF: Noise reduction process took more action + in fact your picture was a little bit out of focus or somehow a very little bit "blur" (at least, see the chain).
If it were not slighty out of focus, your 14M pixels camera could get a photo even more sharper (even without the shapeness process turned ON). I saw such effect on my K200d.
