Yes, it's a shame Foveon wasn't a commercial success, the quality in some areas is close to medium format. You can pick dp Merrill's up on ebay for about $300, would be tempted if it could do half decent video too.

I don't think Lytro will ever take off in the way they intended, but light field capture will be very hot for 3D360 VR in a couple of years, when we start seeing first light field goggles (like Magic Leap)
