This Artefact Camera Futura concept is definitely one that's worth taking a look at. The Seattle-based creative consultancy created a fake video demonstration for this concept piece, so this potential product can, as they say, "spark a discussion around the question of “what if” the product was really available."
The Artefact Camera Futura has a lens with a built-in full-frame image sensor which allows it to be used separately from the camera via WiFi. It also has multi-touch display for more control over taken images and allows the sharing images directly from the camera. This concept has the same connectivity and app platform as your smartphone.
