The opposite of a fisheye is a rectilinear lens. You probably did not find one because your definition is wrong. Distortion of a fisheye lenses is not barrel distortion, it is that a different projection or mapping is obtained by design. Angles are usually preserved but not straight lines, unless they pass through the center of the frame.
