Not sure why canon is suddenly opening up their "R&D" these pass few weeks but here's another interesting "concept". It's an 8mp camera that records HD 4K video and has a fixed f1.8-3.8 24-480mm zoom lens!!! It also has a pretty sweet 4K LCD monitor.

So apparently canon has aspirations to crush RED cameras. It'll be very interesting to see how (or if) Nikon plans to go this route too.
