Lytro has unveiled a light field camera which allows users to click photos and focus later.

It does 2D and 3D and more. Here's the new Lytro camera, coming in 2012. http://lytro.com lets you order this 8GB $399 - 16GB $499 camera.

The Lytro camera is an odd-looking beast, appearing more like a boxy torch than a camera. Two versions will be available at launch, the company has confirmed: a 16GB model capable of storing 750 pictures and coloured red; and a cheaper 8GB model that can store 350 pictures in grey or blue.

That also gives us another piece of information: the size of each 'light-field' image prior to processing. At 750 pictures per 16GB of storage, that's around 20-22MB per image - not bad for a picture that can be refocused after the event.
