I think
@JooVuu's X-cam has a great field of view vs object size when set to 2560 x 1080p. It shows objects about the same size as the Mio 538 or other medium-angle cameras and gives a similar 'feel' of distance from objects as those medium-angle cams, but with the extra 320 pixels of width at each side it offers a field of view that's about as wide as the really wide angle cams such as the Panorama or A118/B40.
In other words: the X-cam is a wide-angle cam that doesn't suffer from anywhere near as much adverse optical illusion regarding distance which is often caused by having wide-angle cams.
