I'm a complete noob when it comes to camera technologies, but i'm interested in shooting panoramic video for viewing on the Rift. So what are the requirements for the lens and would any of these do the job? Samyang 8mm fisheye Samyang 7.5mm MFT fisheye Olympus 9mm fisheye bodycap lens (Only 140 degrees of fov but the price is good.) What about stereo, could i buy two cameras and lenses and shoot stereoscopic video?
