@siracusa the FoV is immutable from the focal length of the lens, for all practical purposes. Because the VR interface requires 180deg FoV, you cannot say use a telephoto lens which might have a 60deg FoV. So how would you get closer in to the subject? Easy way is bring the camera closer. The hard way is what the gigapixel project does and combines tens or hundreds of images to build out the full field of view with a telephoto lens. There’s a third, poor quality option, which is effectively digital zoom. That’s what QuickTimeVR used to do.
