Lytro Light Field Camera

The Lytro may be one of the most advanced cameras ever made: The 4.4-inch aluminum shooter contains industry-first processors and an array of lenses that capture light in such a way that you can refocus images after you've taken them. But the Lytro is also one of the simplest, with only two buttons and a touchscreen zoom-slider. [$400–$500; lytro.com]
