In this case the difference between the nodal point and the flange is relatively minor, so even measuring from the lensboard to the film plane
should make it apparent that telephoto design is not in fact in play. And that's all that this nonsense is about. The official specs are published;
so Stone should argue with Fuji and not us. But a floppy cloth tape????
But still, the distinction is important. Stone would rather argue than learn what flange focus, focal length, and telephoto mean.
