I think there may be an error in the settings for nikon D300 with 18-70 zoom.
I think there may be an error in the settings for d300 with 18-70 zoom.
The distance from the tripod mount to the lens mount on Nikon d70 is 36mm (distance L1 refer- http://wiki.panotools.org/Entrance_Pupil_Database)
The distance from the tripod mount to the lens mount on nikon d300 is 42.6mm (distance L1 refer- http://wiki.panotools.org/Entrance_Pupil_Database
a difference of 6.6mm
I have checked these distances and they appear to be correct
this should mean that there is a difference between the D70 and D300 in upper rail distances for the 18-70 lens
however, they are listed as the same settings on the nodal ninja camera settings page
if the d70 figures are correct then I would expect the d300 settings would be plus 6.6mm for each focal length
Perhaps other who have used D70 and 18-70 or D300 and 18-70 would post their settings
the settings i have used (below) for d70 and 18-70 are different from those on the nodal ninja camera settings page.
