Nodal point database availability

[GEB1]

Does Canon maintain a database of lens nodal points?

As far as I am aware there is no public list of Canon lens nodal points available from Canon. Several online resources explain their own findings and have short lists of specific lenses commonly used for panoramic photography.

Your question is not making sense, to me.  There can be an infinite number of nodal points, varying by the distance to your subject and distances to objects in the foreground.  Once you add a nodal rail into the mix you can get a near infinite number of points. 

The setting that makes the most sense is when the image sensor is aligned over the vertical axis of rotation of your tripod head and focus is set to the hyper focal distance. 
Personally, I don’t think about nodal points. I simply avoid having objects in the near foreground.  

My “go to” lens for capturing a series of images for a panoramic photo is my 70-200mm.  The foot aligns the lens over the vertical axis of rotation. And, I can roll the body to portrait mode and maintain that alignment. Much easier than using an L-Bracket.

Avoid foreground objects and it’s not a problem.
