k-7 sharpness / fine sharpness / fine sharpness 2

With a little compare-o-matic thing:

I think Fine Sharpness 2 looks best at higher sharpening settings, but tends to increase jaggies on the diagonals and contributes to a loss of distinction of detail in brightness. Because of this, I think regular sharpness looks best at around the 0 setting. Anyone agree?

I thought FS2 increase sharpness without increasing noise and very little artifacts. A good compromise of the other two...but, after you mentioned I notice those jaggies in diagonals, but I still prefer FS2. If you click back and forth even at 0 sharpness between regular sharpness and FS2, I think FS2 at 0 looks better than regular sharpness at 0 which shows jaggies with diagonals at 0, and FS2 doesn't and is actually sharper in the feathers. I like FS2 very much.

Very intersting link, thanks. Just don't forget these are 100% crops, though. Even if you printed these out at full size you'd have to look very, very closely under excellent light to see the differences/artefacts in e. g. the hairy texture. So I would say these settings are only relevant for rather special applications, especially when you're actually using a sharp lens.

Anyway, at all settings I find FS to look worst. At '0' settings it really depends on whether you look at the hair or the calculator on that picture to tell whether S or SF2 looks better...

Cool comparison. Fine Sharpness looks very nice to me, but I would never apply in-camera sharpening so the point it moot. Sharpness depends on the image and destination and cannot easily be applied as a global choice.
