I've been waiting forever for this to come out. When I first saw this, I was like, "I want one now!" It's still on pre-order, prices aren't too bad, but there's no announcement yet of when it'll actually come out, except for "Early 2012". And why does it only work on a Mac?! I really hope this gets off the ground. Who knows, 10 years from now, your kid will say, "How come this photo is dead?!" when they see one of your pics from 2012.
At the moment, it's not going to replace "serious" cameras. But the technology is amazing and when you talk to the on the Lytro team about what they could theoretically do going forward it's pretty neat. The cameras themselves won't be the easiest for some of you to handle. The touch screen LCD is small and the few controls on the body are not particularly easy to feel. It's really more in a trendy "early adopter" form factor right now. That will probably change in the future as the 2nd and 3rd gen products come out.
Very VERY neat though. I can't wait to get one in my hands for a full review.
There's not really any way to say that with any accuracy.
After all, consider this. Given the way the the light field cameras gather information, you could have a Lytro camera that could eliminate all lens aberrations simply by knowing what they were and where they existed in the lens/image circle and then calculating for that fact when processing.
It's really a fascinating concept when you start too look at what they should be able to do with it.
