This point is not located at the same point, depending on the focal used in a zoom lens. If you in the field realise that you need another focal length you could either calibrate it in the field as shown in the video or perform some crude interpolation from the data you've already got. I still think that the same method, meaning in-hand or not at the nodal point, would be disastrous if we shot a close subject and distant at the same time. Tokina I'll stress again, but I already explained why above, that the less you shoot close subjects, hence beautiful and distant skylines, the less the problem of the nodal point (of the entrance pupil) is raised. Edits There is a quick way to get a very close estimate that usually works great, or is a close starting point for a more accurate one based on testing. Just adjust the rotation point so that foreground and background points stay lined up. For that, an incoming beam from the input side must be directed to the front nodal point, and the corresponding output ray then appears to come from the back nodal point.
