Nikon Coolpix S4000
The inexpensive Nikon Coolpix S4000 sports a 3-inch LCD touchscreen, a wide-angle lens with 4X optical zoom, 720p high-definition video capture, and four-way image stabilization.
You can optimize the focus for subjects on the screen by touching the screen, and you can fire the shutter this way. The motion-tracking autofocus responds to touch control as well. Despite its affordable price, the Coolpix S4000 doesn't skimp out on features.
