It's a constant f/2 lens, but that's fairly irrelevant as, given the way the camera works, you could use focus stacking to get the whole frame in focus if you wanted. Of course, that depends on either software features or a lot of manual labour, which is why my main question about the device is how open/hackable the image format is. I'd love to see the applications that come out of this - eg. ultra high-res 3d scanning from only a handful of photos - so I hope they've created it with a view to encouraging indipendent development. It seems the examples are there just to showcase after-the-fact focusing, and that's clearly most easily done with a shallow DoF.
