With my Nikon N90/16mm fisheye, the nodal point is within a few millimeters
of the farthest front edge of the lens. Found by setting a light stand a
couple feet in front of the lens, lining it up with a vertical across the
room, and then sliding camera forward/backward until the light stand and
vertical do not move relative to one another when the camera is rotated on
the tripod. Is that the "Parallax Test"?
