The 55mm Center Pinch Snap-On Lens Cap from Photomaa is a front lens cap with a squeeze, spring, and snap-on mechanism. It is easy to put on and take off, especially when using a lens hood, and it stays on. Lens caps protect your lens from scratches, fingerprints, and the elements when the lens is not in use. It's always good to have a spare in your camera bag, too
