Hi!

This is called "purple fringe". This effect is coming from the lenses. 
It is a form of chromatic aberration (CA), and I would say it is 
"normal" on low end cameras/lenses. If you want to avoid this, usually 
you have to spend a lot :) (eg. buy a DSLR and lenses with low CA)
If you are more interested go and type purpe fringe into google.

Gabor
