Nodal Points on 90-280mm in Leica SL System Posted August 27, 2017 · Edited August 27, 2017 by tthorne I am measuring it for the purposes of shooting a panorama. I think that "nodal point" is actually a misnomer in this case and I am looking for the exit pupil or the point of no parallax. There are some videos online demonstrating the method that I use. Essentially I mount the camera/lens on the tripod and place one nightstand directly in front of it about 65" away and another one directly behind that about 250" away. Then I watch on live view and swing the camera back and forth. As it moves left to right the rear light stand becomes more visible. So then I adjust the rail moving the camera forward or back until the two light stands stay in line despite panning left or right. This has always been easy, but I have never done it for a focal length this long.
