Made of high quality anodized balck aluminum(metal). Color: Balck. Extremely solid and lightweight. Specifically designed for your camera for a tight and secure fit. No wobbling or cross-threading. Your camera's lens thread size will be marked somewhere on the lens barrel. This number is always preceded by a (diameter) symbol. For example: diameter 37 = 37mm lens thread size. This number can also often be found printed on the back side of your lens cap. The first number is always the lens thread sie, the second number is the filter size of the accessory. If the first number is bigger, it's a step- down ring. If the first number is smaller, it's a step-up.
What is a step up ring? Step up rings, also known as adapter rings, allow you to use filters and accessories that are not the same size as your camera lens. Lenses and filters come in a large range of types and sizes and unfortunately they don't always fit together correctly. Fortunately there is a step up or step down filter for just about any need.
How step up rings work? Step up rings provide a way to fit a larger diameter or accessory onto a smaller lens. The step up rings screws onto your lenses threading and provided a largee thread with you can attach other elements inclued more step up rings.
How step down rings work? Step down rings work in the exact same way but instead provide a way to attach smaller accessories and filters to larger lenses.
It is important to note that typically, the farther away from the lens you place a filter the worse the optics will be. It is always best to look for the thinnest adapter ring that you can find as these will keep the filter close to the lens.
