Just need a bit of advice on if I should purchase a used NN5 or a new (irregular) NN4 (they are close enough in price that price is not an issue). Both are starter packages with the basic rotator. I plan on using this head for spherical panos, and plan on getting Pano2VR or something similar.
I have a 5DIII and for the time being plan on using a 16-35 2.8. But I also have longer lenses I could use.
What advantages/disadvantages are there in buying one over the other?
