Like the other Nikon lenses in the trinity, the Nikon 14-24mm lens was designed for full frame (FX) camera bodies. That's actually good news, since it means it will work just fine on Nikon DX and mirror less camera bodies. The only time you have to be concerned is when you try to use a DX lens on your full frame camera. This lens is a good investment for the future, as Nikon stated it will stop making new DX camera bodies now.
