Light Field Cameras allow you to focus after the fact...

This is pretty crazy, could see it working great on reef tanks...

Go to the 'picture gallery' and you can click on different parts of the picture to refocus. The butterfly and spider pictures are pretty good examples, haven't looked at them all yet though. There are some science pages that explain how it works. Pretty reasonable price tag too, considering... Crazy

I'm on several photography forums, one of which has quite a thread going, about this camera. There's a lot of debate about how and if it'll really work as well as their site says it will...lol. We're all waiting for someone to actually buy it, to find out. So far, no one is willing to do that.

Wow! Rob, that's a pretty amazing camera... or can you really even call it that. Definitely would be cool to try it on a reeftank shoot.

Cheers, Todd

For the price it isn't a half bag gadget, really. I would be curious as to what the timeframe is for a Windows based software release date, as it is only shipping with Mac Based software at the moment.

Here's a good place for more info on it,
