Which point and shoots (any brand) have the fastest autofocus for action shots of kids running around, etc.?
I already have a satisfying DSLR system with a couple lenses, but for a vacation coming up (cruise) I'll want to have a point and shoot that I can throw in my pocket and not worry about a camera bag.
I don't mind spending the money on something nice.
My thoughts are on the S100/110, the Sony RX100, and other similar models. I want it to be pocketable (so no G15 kind of gear), and I'm not that concerned with low light performance. I mostly want blur-free photos for around the various ports and on the deck of the ship. My Iphone 4s takes great pics, but not if there's movement of the camera or the subject.
