Determining the nodal point. FM Forums
Do not try to center the lens at the axis point of the tripod. This way you know you only have to move the vertical arm to one side until you hit the "point". This way you know you only have to move the vertical arm to one side until you hit the "point".... NODAL POINTS Are two axial points, such that a ray, directed at the first will seem to emerge from the second nodal point parallel to its original direction. A ray directed to a nodal point at a certain angle, will exit the lens at the same angle. Graphically,extending the incident and emergent ray towards the inside of the lane will intersect the optical axis at the primary and second nodal
What is NODAL POINTS OF A LENS Science Dictionary
It seems that they operate with two nodal points of the lens. These are defined as the two points in a lens such that a light ray entering the lens and hitting the point (N) appears to exit on the on the other side of the lens from the other point (N’) When we need more acuity, the lens changes form (we accommodate) and then the nodal points move.

23/01/2006 · I am new to this whole panoramic photography idea, and I just received a nodal ninja for Christmas. After extensive research, I have discovered that no one has taken it upon themselves to publish any kind of useful chart that would display the precise nodal points for all these lens… how to get pepper seeds to germinate 2/12/2016 · Hi all, I have just bought the 50-140 and although having read loads of reviews/threads on the lens I don't seem to be able to find the answer to my query which is, is the pivot point on the tripod mount of the lens actually the Nodal point as well?.

It’s not absolutely necessary for your tripod to have a pano head in order for you to find the nodal point. You always have the option of checking for any mark that may have been put on your lens by the manufacturer to indicate that point. For example on the AF DX Fisheye-Nikkor 10.5mm f/2.8 ED lens, it’s indicated with a yellow ring around the lens circumference.
- find the nodal point of your lens manually. Specific information you find elsewhere with respect to Specific information you find elsewhere with respect to where a nodal point may be located on a lens should be taken with a bit of concern to accuracy.
- Panoramic Pivot Point Defined: The rotational point at which the alignment of all objects seen through the lens stays the same, even as the lens+camera is rotated on a tripod. NOTE: The proper pivot point is not the lens "nodal point" (stated elsewhere on the Internet), but rather the center of the lens Entrance Pupil ., For details, check out this detailed paper on the subject.
- The nodal point varies from lens to lens but it almost always lies between the front and rear element of the lens. The sensor, or in days of old the film plane, is not the nodal point. The sensor, or in days of old the film plane, is not the nodal point.
- Notes: If you use zoom lenses, a lens' optical center (frequently and incorrectly referred to as the nodal point) changes for each focal setting.
