I use a Metabones dumb adapter to connect my few remaining Nikon lenses to my Fuji X T-2. It has an Arca foot, which depending on the lens, can be used on my Acratech head. I'm down to the three PC-E's and an ancient MF Micro-Nikkor. Roger at Lensrentals seems to have a dim view of all adapters since tolerances can vary. Some seem flimsy but I've felt pretty good about the Metabones. I'm sure the noble name of Novoflex is a guarantee of quality though there is the word "flex" in the name :-). As EJ Peiker notes, there is currently no available adapter that will allow use of any of Nikon's E lenses on any mirrorless camera. I set my Nikon PC-E's aperture with a Nikon camera by mounting it, setting the f/stop, and unmounting it while holding the depth of field button so it stays at the set aperture. This is far from ideal but the EVF on the Fuji (and Sony) is bright. Focusing is a bit tricky at times but it works. Hope this is helpful.
