So that would be a yes.

Reading from Jim H and below why not get a Flickr or Picasa account and  
stick them all up their?

Heh I would suggest reading the manual, but having read about five or six  
for various models I won't say that'll be any help. They barely tell you  
what the camera does let alone how it actually works :-)

Well yeah that'll do it :-)

Had a quick Google and it seems a standard multi-point focus with face  
recognition. So it should spot faces and try to focus on and expose them  
all automatically. I'd have thought that might cause a problem with delay  
if you're moving, but your test photos look fine
