Waht were your settings. I don't see the exif so it's hard to tell what's up. One thing is poor focus. It looks like a long zoom shot probably with a wide open aperture.

Using a wide aperture at full zoom, out of focus and a high contrast area will do this every time. Just about any camera would have a hard time with those conditions. Try to avoid shooting wide open f2.8 at full zoom in shots like these and getting things in focus will be a big help. Keep practicing8)

Is it more noticeable on Digi Pics that 35mm? Because I did not remember to such firing on 35mm slides.-

Lens and sensor size can effect CA/ purple fringing

35mm film is not susceptible to the same chromatic aberration as a digital camera. the CA phenomenon itself is a function of the lens, as i understand it, but the sensors in digicams are much more sensitive to it than emulsion-based film.

This "red fringing" is a known and unique issue with the FZ20.

You eliminate it by avoiding zooming to the maximum 12X and by keeping your aperture above f5.6 for high contrast shots. So zoom to 9X or 10X and crop later for a nice tight shot and keep the aperture small.

CA is not "unique" to the FZ20. It is a common problem among digicams.
