Huh. I always thought a shallow DoF was what everyone is chasing with the larger sensors. The smaller sensors on a P&S literally have an infinity focus and a correspondingly deep DoF, which is why they have a fixed focus.

I'm not aware of any compacts with fixed focus (they all have AF).

"Focus-free lenses accomplish their magic by relying on depth-of-field and wide-angle optics....most fixed-focus lenses are calibrated to what is known as the hyperfocal distance. This is a photographic concept that establishes the closest distance to the lens that objects can remain in focus, while still maintaining sharpness at infinity."
