NR-100mm plate purchased to give posiibility of rotation around the nodal point for simple horizontal panoramas. Knowing the "length of extension" of plate for a specific set of camera+lens, you can set the camera in such a way, that the rotation of the tripod head will also be rotation in the nodal axis. The only thing you have to assure is to proper length of the plate according to your lens. Luckily, Leofoto provides three lengths. The NR-100mm one is perfectly matched to my lenses.
