Smartphones are evolving into mini portable computers that can do so many things, yet their small size has made it difficult to really ramp up the camera technology. That goes for pretty much everything in a smartphone, even the iPhone 4S. The small size is a challenge for many of the components, especially batteries. But poor batteries and lousy cameras are two of the biggest reasons so many handsets nowadays just don't measure up to their massive price tags.

Apple leads the pack in smartphone cameras, except for one other device. The little known Sony Ericsson Xperia Arc S has the best smartphone camera on the market, and the Carl Zeiss lens-sporting Nokia N8 is not far behind either the iPhone or the Arc; it's just not available in the U.S. Besides being less widely known than many other devices, the Sony Ericsson Xperia Arc S is not offered by any of the major U.S. carriers. That means it is not sold at a subsidized price like many popular devices from AT&T, Verizon and Sprint. It does have the best camera though, and for $500 you get Android inside, a 4.2-inch screen and over seven hours of talk time. Behind the Xperia Arc S and the iPhone 4S are three other nifty camera phones, just start the slideshow to find out what they are.
