I've seen my Canon PS-400 do exactly the opposite; focus on something in
the foreground when my subject was further away.

Well, yes. I should have said "focus on something other than the subject
when the subject has relatively low contrast". It's _really_ irritating.

As I understand it, the dSLRs can do that also, but the AF sensors are quite
a bit smaller so it's much less of a problem (if you select the AF sensor
manuallyg).
