I had a similar response when I learned of it.
It seems to me that this is a camera that simply captures one
additional dimension and that is depth-from-lens. Then, it's simply a
matter of having software to interpret that data.
Don't get me wrong -- that IS a very clever thing to do. I've used
ultrasonics to build topo maps before -- and building an HD topo map
at the same time you're shooting an HD image at, say, 30 fps, is no
cake walk. The old Polaroids used basically the same technology, and
you can get more sophisticated ultrasound tech nowadays.
Unless I'm misunderstanding something, this is one of those solutions
to a problem whose solution set happens to include "pull focus right
the first time."
It also seems useful if you've got elements you're shooting that offer
a depth-of-field challenge, such as a character walking toward the
camera through a complex setting (say, trees with hanging vines).
Trying to maintain focus with a shallow depth-of-field in that
situation can be... tricky. I guess a device such as this, where one
can fiddle endlessly in post customizing one's DoF can help fix such
things.
Assuming post is cheaper than production.
But I could be wrong. It could be something far more sophisticated.
So, yeah, seems like you and I had the same response. 8)
