Ron, the only wide angle auxiliary adapter lens that I have any knowledge of is the marexar UltraWider. I have one. It is designed for use with a 50mm lens on a 35mm film camera, giving a focal length of about 28mm. If I attach it to the front of my Nikkon 18-55mm lens, it only works at the long end. If I zoom to around 35mm it vignettes badly. I think that all wide angle auxiliary converter lenses work this way. You may, however, find a fish-eye adapter that will work, but the image quality is likely to be very poor.
Age brings wisdom....or age shows up alone. You never know.
