There is no theoretical reason to believe that the nodal point will be
independent of the zoom setting. Nevertheless, the nodal points the
lenses I have actually tested vary little if at all with the focal
length. The nodal point will also vary with the focus setting, but
only for the macro at close focusing distances would this be likely to
make much difference.

a quick and dirty way of finding the nodal point. My own method is
even dirtier, substituting the kitchen table, my wife's lazy susan,
and a couple of crossed rulers and a drafter's triangle for the tripod
