A recent patent filed in Japan suggests Canon could be working on a new tilting EVF (electronic viewfinder). The patent goes into detail about how such a tiling mechanism would work, specifically how the interconnect cable between the main body of the camera links to the tilting portion of the viewfinder. The length and routing of such a ribbon cable is critical, to ensure years of repetitive movement don't stress, pinch or fatigue the cable to the point that electronic communication is severed and the EVF ceases to function. As is shown in the patent diagram, Canon's EVF design looks like it would tilt from horizontal to almost vertical. With a near-90-degree tilt therefore requires the flexible interconnecting cable to have a significant range of movement, hence the engineering challenge.
