Interesting and extraordinarily clever, but novel. It's not small and I can't help but feel all those angled low grade mirrors are going to flare to hell and be problematic at some point. It will need some considerable development.
The only benefit I see is being able to focus retrospectively but to be frank I have no interest in that, and since the lytro cameras have pretty much failed to capture peoples interest, it seems no one else cares either. To me, it's not even what photography is about. Part of the joy and art of photography is the instant of reacting and making decisions to manipulate a camera that represent your thoughts and feelings
at the instance of capture. Sure, having some things that do that automatically helps, but too much is not a good thing, IMO. It's like buying one of those piano's that plays its self, stupid.
Why can't you just use a normal camera?
I'm sick of all this dumbing down tech.
The thing is, it's not us who decides what the future wants, it's the future that does that and runs with things. Maybe they want this stuff? No one can predict that, but I hope they don't. What I can see is someone like apple taking elements of this and using it in consumer equipment.
