Alex Notpro: Being able to fix the focus in post-processing may just be a gimmick. The real advance in this technology is the ability to get shallow Depth Of Field in a small sensor. The first company to get this tech into a 10MP enthusiast compact will take a huge bite out of the DSLR market. People who fret over the coming obsolescence of DSLRs should be very nervous now.
You can't get any shallower depth of field with this technology than with conventional cameras @ same sensor size. The secret behind a shallow depth of field is the combination of a large aperture and a large focal length. The problem with small sensors is that you will only get a very narrow field of view when using a large focal length. As a light-field sensor doesn't have a clue about light-rays not hitting it because it is too small (the same issue as with conventional sensors), this technology doesn't allow virtual sensor enlargement. Hence, you can't get shallower depth just because you are using a light-field sensor instead of a conventional one.
If you don't want to have to like something on facebook, but still want to use the MegaZuck84 camera, take a look at the app called "aremaC". In its online library you find this camera as a free preset, too.
