The package includes: 1 elevating ring Use lifting and lowering rings for better photos What is a lifting ring? Lifting rings, also known as adapter rings, allow you to use filters and accessories that are not the same size as the camera lens. Lenses and filters come in a wide variety of types and sizes, and unfortunately they do not always fit together properly. Fortunately, there is an elevating or offset filter for almost any need. How do the elevating rings work? Elevating rings provide a way to mount a filter or accessory with a larger diameter on a smaller lens. Elevating rings are mounted on your lens threads, and a larger thread is provided with you, then you can attach other elements that include more elevating rings. How do offset rings work? Offset rings work in exactly the same way, but instead they provide a way to attach smaller accessories and filters to larger lenses. It is important to note that usually, the farther you move a filter away from the lens, the worse the optics become. It is always better to look for the thinnest adapter ring you can find because it will keep the filter close to the lens.
