Stop buying multiple filters for each lens size. This 18-piece step up and step down ring kit lets you use a single filter across your entire lens collection by adapting between different thread diameters. Simply match your filter to your largest lens, then use the appropriate ring to fit it on smaller lenses. Save money, reduce clutter, and streamline your photography gear with one versatile solution that works with wide, standard, and telephoto lenses alike.
What is an adapter ring
Step up rings or step down rings, also known as adapter rings, allow you to use filters and accessories even if they are not the same size as the thread on your cameras lens. Lenses and filters come in a large range of types and sizes and unfortunately they don't always fit together interchangeably. Within this wide range of possible sizes there is at least a level of standardization. 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 filter or accessory onto a smaller lens. Every adapter is a metal ring with a male and a female thread. The male thread screws onto the lens, the female thread accepts the accessory. In the case of a step up ring, the male thread is a smaller size and screws onto your lenses threading. The opposite side has the larger diameter female thread, to which you can then attach the filter or accessories or even more step up rings to match diameters 2 or more steps larger.
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. So their male thread attaches to the front of the lens, and on the opposite side of the ring in a narrower diameter female thread.
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. Stacking adapter rings or using step down rings may lead to vignetting as they become visible withing the cameras field of view.
