Don't use the any wide angle adapters, yes there cheaper than the real thing but the image quality will suffer. Just purchase a real lens, the 17-70mm Nikon DX is a nice lens but the 17-55mm Nikon DX some people like better, either lens will give you standard wide angle of 35mm equivalent of 24-25mm to 75mm(55mm) or 105mm(70mm) to short telephoto. The 50mm (75mm, 35mm equivalent) length is a grate portrait focus length .
