Well you could go with any of the primes like the 20mm f/2.8 at about $500. Great for low light landscapes and, close-ups. It has about a 10.5 focusing distance and, a 94 degree field of view. Or I would go with a fisheye for maximum wideness and, playability. In that case Sigma makes an 8mm f/3.4 or, f/4 the first is like $50-60 higher than the second. Myself I plan on a fisheye next. Minimum focusing is like around 5 inches.
