The Linkstar TTL cable OSC-N1 is suitable for Nikon cameras. You use this cable to disconnect your camera flash from your camera, for example when using a softbox for your flash. Using this cable you control your camera flash from a distance. The great advantage of a TTL cable is that it ensures that all your settings for the camera flash are transmitted from the camera. The length of the cable is 1.5 meters, when fully extended.
