The S2IS in-camera sharpening has a tendency to create jagged edges on
narrow parrallell lines, as can be seen on test photos such as this one:

The sharpness can however be adjusted in the manual setting modes. There is
a setting called "low sharpness". This makes away with almost all of the
jaggedness, and is not a softening effect at all.
Iinstead, in my opinion the "Low sharpness" setting should be called
"Moderate Sharpening", and the standard sharpness stetting should to be
called "Excessive Sharpening" as this is what it does.
More sharpness than the "low sharpness" setting is much better applied,
using PhotoShop.
The Panasonic FZ5 has also produced jagged lines in the same test as above,
and could probably be adjusted in a similar manner too.
Most SLR's have very moderate in-camera sharpening, and it is a pity that
zlr's should suffer from bad compromizes such as this.
