So basically the camera take 8 photos at the same time on fixed focal planes and combines them into a meaningful image in software that the user can then tweak between the planes but not actually fine tune the focus in any given plane.

So by reckoning that means all they have done is to figure out how to split the sensor up into sections with light focus differently across it's face to basically build 8 pictures taken at the same time. Like I said, it's just taking multiple pictures at different focal lengths from the exact viewpoint at the same time. With some very clever software working it all out.

I'm not impressed with the website of the examples they give. None of the images really work very well and you clearly can't fine tune focus and everything seems to be slightly out and low res. Still, I look forward to having a play.

Cheers
