Pretty freaking cool. Small form. 8x zoom, constant f/2 aperture, no autofocus motors instant shutter, 11 mega-ray (don't ask me) and you focus AFTER you take an image.

Only still now, but dang. What cool technology. We got rid of 2nd AC's (no film to load), in a few years no more 1 AC (follow focus, what's that??) haha.

This is definitely impressive, and nice to see it finally coming to a real product - unfortunately I think it'll take a few more generations to become practically useful. Each pixel actually captures a grid of light samples from different angles - this is what allows it to do what it does, but it also means the final image is pretty low resolution. So when they say '11 mega-rays' that includes all the samples... even if each pixel contains just a 4x4 grid of samples that ends up producing a final image with a resolution of just under one megapixel. I suspect they may use more than 4x4 samples though, so the final images are pretty small. I wouldn't be surprised though if five years from now we see HD video cameras with this tech starting to show up - another possibility the technology enables is the ability to generate true 3D images with a single camera & lens.
