Many wide-angle lenses are amenable to reverse mounting, which gives typical magnifications of around 5x or higher. Also, the working distance is almost constant (about the flange distance, so ~40-something mm for SLR lenses) across the range of magnifications, unlike macro lenses where adding extension continually reduces working distance until it gets zero/negative.
