I suppose if I had my choice I would bring a fixed 24MM lens and a longer reaching one such as 100-400MM but for my camera 24MM is pretty wide.
you forget that his D2 is a DX sensor (1.5x multiplier), so to get to a 24mm lens perspective like on your camera, he needs a 16mm lens. The 18-55 I use is equivalent to a 27-80mm made for full frame bodies.
to get to a 14mm like in my samples above, you would need a 9.5mm lens made for DX - it does not exist.
