What is a wide conversion lens?

I believe that what you are describing is an adapter type of lens made for cameras which don't have interchangeable lenses. It would attach to the front of your existing lens to make the angle of view wider. I had something similar for an Olympus E20N to do close-ups. I also had a telephoto converter for a Canon SureShot. Both cameras came with a permanent non-removable lens. And the converter attached to the front, like eye glasses. On other cameras, where you can remove the lens entirely, you simply put on a wide lens and you are not converting.
