Yeah, I know this isn't completely Star Wars related but has anyone heard of the red one camera system? It's a digital camera that shoots in 4k as opposed to 1080p resolution.
Here's a high-res screencap from one of Peter Jackson's short films.

I wonder if the prequels would have looked better if they were shot with something like this (obviously the tech wasn't available at the time)
