Can anyone suggest a good reading on those 3 point, 9 point auto focus? What are the advantages and applications? Because so far I've used powershot (3 pt), lumix (9 pt). But I always forced to them to 1 pt auto focus.
Should it be really a deciding factor when buying a cam? Because now I'm confused whether to buy D40 or 400D. Will it make a difference using 3pt against 9pt AF?
