I have an NN3, the new Nadir adapter and the RD16 rotator. Now that I have fitted the battery grip to my Nikon D300 I can no longer place
the camera over the rotation axis.
Is the lower rail from an NN5, along with any extra bits I need to attach the NN3 upper assembly, available seperately? Or do I have to ditch the NN3 and purchase a complete NN5?
