AS-N1000 Multi Accessory Port Adapter

This adapter is only realy useful for holding a microphone. Contrary to another review, a flash mounted on this shoe cannot be triggered by a V1 or V3 camera because only the V2 has a pop-up flash. This is a cold shoe. Besides, a mounted flash inhibits the V2´s built-in flash from popping up enough to trigger another mounted flash.

In other words, if you want to trigger a regular Nikon Speedlite (SB800 / 600 / 700...) you´re best to use a Nikon 1 speedlight that triggers a separate slave shoe that in turn triggers another flash -- that´s the safest and surest way to make sure an external flash can fire properly. You´ll have to shoot in manual on the on-camera flash, and M or (regular, non-TTL) auto on any other flash.

Otherwise, you´d be better off with a tripod-mount-screw-on bracket

Mount the SB900 in the cold shoe and put it in remote mode. Use the pop up flash as the commander.

This is a COLD SHOE adapter since you cannot trigger flashes, like the SB-900. It ha limited usefulness, especially since the Nikon website does not even have a picture of this. If there were a picture, almost no one would buy this.

This is a nice camera system, but it desperately needs a hot-shoe adapter, or at least a cold-shoe mount with a PC-sync port. This accessory is strictly a cold-shoe adapter for mounting microphones or other cold-shoe accessories like leveling bubbles. Off-camera flash is critical in many applications, and using optical triggering is a method of last resort for most serious users of off-camera flash.

Many reviews call this accessory a hot-shoe adapter, but that is not correct. Nikon itself does not describe what kind of shoe this is (hot/cold) I have one, and it is absolutely a cold-shoe adapter.
