Harbor Digital XT-A26 XT Flash Extender Kit for Nikon SB-900, SB-910 Flashes

The Harbor Digital XT-A26 XT Flash Extender Kit (Nikon SB-900, SB-910) can add up to 2 f/stops of exposure at 100 ft (30.48 m) from the camera. Just mount the XT Extender directly to your Nikon SB-900, SB-910 using the included mounting system (no straps or touch-tabs required) and you're ready for those wildlife, sports (indoor or outdoor) or any other shots at a distance previously too far for your flash to reach.
