This item is new and unused, although it has been opened for inspection. A convenient storage bag is also included. Genuine telephoto lenses are quite expensive, but this third-party lens is available at a much more affordable price. If you're considering a telephoto lens to "try taking pictures of the moon!", please give this a try. Enjoy the world of telephoto photography.
