It's easy enough to test this but you do need a nodal slide or other rail on which to slide the camera forward and backwards while remaining level. Set up on a tripod and place two objects in the scene, one at close range, the other near infinity. Pan the camera on the tripod left to right and adjust the fore-aft position of the camera body (via the nodal slide) until the rear object stops shifting position relative to the close object. When they remain aligned while panning, you've found the nodal point.
