Contrast detection vs Phase detection Autofocus

Seeing descriptions of the 420 and reading about it's Autofocus mechanism made me wonder a little more than I have done before of the mechanisms

Focusing System
Method TTL phase difference detection system, contrast detection system
Focus areas 3 points / Automatic and manual selection For contrast detection AF, 11 points are used
so a quick surf later some links are offered for your delictation should you be interested ...

Oh BTW Ian/John.... E-420 needs adding to the categories in this forum section
