You should be able to find a generic 77mm wide-angle screw-in hood that will do the job. Your problem isn't unique - except that you already have the larger filters. Many of us have followed Nikon from 52mm to 62, 72, and 82mm before standardizing on 77mm. I use this size on everything except my lenses that take 52mm.
