The SC-28 provides full TTL control for Nikon Speedlites when used off camera with Nikon SLR cameras which have the TTL hot flash shoe. Approximately 9' (3 m) long & coiled, it permits easy use of flash when the camera is mounted upon a bracket.
This cord replaces the SC-17. Improvements on the SC-28 over the SC-17 are: Posi-Lock (an improved locking switch) and the cord on the camera shoe that now connects parallel to the camera.
Suitable for D3, D700, D300, D7000, D90, D5100, D5000, D3100, D3000
