Using this Fujinon lens is easy. Just attach it to your device with the 1/3-inch bayonet mount. When using, be careful not to touch the lens surface directly to avoid more scratches. For maintenance, use a soft lens cloth to gently wipe the lens. If there are stubborn stains, you can use a small amount of lens cleaning solution.
