I would go for the Panny FZ200 well ahead of the canon ...
I am biased here - we're a Panny household
- Equally, in playing with other superzoom cameras, I have noticed that most zooms over about 20x zoom start to fall down on either sharpness &/or colour fringing
- I have also found from personal experience that the IS features in these cameras also start to lose their efficiencies when the lens is over 20x zoom as well
Your choice must come down to ergonomics / hand & eye operation as well as the list of features
hope this helps -
