The Lytro Camera ($400-$500) is an all-new type of shooter called a Light Field Camera that captures the color, intensity and vector direction of the rays of light — 11 million of them, in the case of the Lytro — and then uses powerful software to substitute for the internal pieces of regular cameras and also add incredible new capabilities, like the ability to focus the photo after you've taken it.

Form follows function.
The Lytro Light Field Camera boasts an 8X optical zoom lens with a constant f/2 aperture, capturing maximum light across the entire zoom range.
Intelligent design.
Extruded anodized aluminum structural skin. Center of gravity shutter button. Intuitive multi-touch screen. And less than eight ounces. What does it all mean? A meticulously designed camera that's lightweight yet solid, built for stability, and easy to use.
Speed, indeed.
Light field technology translates to faster snaps. Without an auto-focus motor, the Lytro's instant shutter means you don't lose time focusing. Plus, with instant power on, you can capture the perfect moment – not the moment after.
Elegant omissions.
What's missing? Nothing you'll miss. No auto-focus, no shutter lag, no unnecessary modes, dials, or settings. And no flash, because Lytro can handle many low light settings. So, no obstacles to the perfect shot.
