The Bower 4.0x Telephoto Lens is a long-telephoto add-on lens that attaches to the front of your existing lens with a 37mm filter thread. Using this "auxiliary" lens is an affordable way to expand the capabilities of your current lens and is particularly useful for unusual closeups, nature, and other subjects that are far away. With this telephoto your 100mm lens will become a 400mm.
