Panorama Panning Base - Nodal Points for Mamiya RZ 67 Lens

Anyone know what the Nodal Point measuremenst are for Mamiya RZ67
lenses? (I have a 180mm and a 110mm lens). I am curious whether the
Really Right Stuff Panorama Rails are long enough for MF work. Anyone
ever tried panos with such gear, Really Right = Really expensive. I'm
a pano newbie, just looking to try this out.

Thanks!

Its the entrance pupil location you want, not the nodal point. For the
110mm it is probably within a few millimeters of the iris diaphragm.
If the 180mm is a true telephoto the entrance pupil will be fairly far
back into the lens. Some of my 35mm telephotos have an entrance pupil
location *behind* the image plane, but I doubt this will be the case
for your 180.

The best thing to do is to use the parallax method to measure the
entrance pupil location for yourself.
