Well, now, tony, I disagree with you on this: Why disagree with a

But not all of them, as you well know. Perhaps he makes you feel

But those of us who feel he has something to say, and/or don't feel in
the least uncomfortable about having our buying decisions questioned,
can choose for ourselves whether or not to reply. Our choice.

Under ideal conditions. But in low light or in the tele range also phase
AF hunts for a while until it locks.

Tele works just fine on my Nikon camera and lenses. In situations where
phase-detect hunts before lock, contrast-detect will likely fail

In the cases where contrast-detect fails completely there is too little
light to take the picture anyway. The flash is too weak and the pixels
too small on P&S camera with a tiny sensor. Also there probably is no
optical viewfinder to frame the photo in the low light. The failure of
contrast detection in those circumstances is doing the user a favor.
Now if it's a ZLR or something like the G11 with an external flash,
where you probably could take the picture if you could focus, you could
always try manual focus.
The bottom line is to not try to use contrast-detect AF in very low
light. Even if you can focus, the results will still suck.
