I have a NN3, and am very happy with it. I recently came into possession of a D700 w/ 14-24/2.8. The upper arm on the NN3 is not quite long enough to set the nodal point on the 14-24.

Will the RD16 that I already own work with the NN5? Can I buy just the arms (which are still in stock), or do I have to buy a new rotator as well?

I searched the forum, but wasn't able to find the answer.
