I found the only item that can be used with this adapter is my Sb-800 flashes. There is no hot-shoe base it is a light-stand screw only mount on the bottom. The coiled sc-29 and sc-28 cords do not have a socket to attach to this adapter. So it is only good for connecting two or more flash units together at the limiting cable length of 5ft. The sc-27 cord (sold separately) is all that connects to this adapter, nothing else connects to it. Nikon fails to install the same socket on many of their camera bodies. Which makes this adapter useless to many models. The connecting cords are very costly and too. You need to piece together several units and cords to get any proper lighting or distance.
Equipment should never limit your art, but add to your abilities instead. A very poorly thought out system, where to few cameras use the required cord. None of the coiled cords connect to this adapter. So where was Nikon's thinking on this one?
The coiled cords just pull over or topple equipment and the Sc-27 is expensive and too short to do the job. Nikon just misses the boat with adapters and cords. Save your money buy radio triggers instead. This item is worthless, expensive and unsafe.
