What is a step up ring Step up rings, also known as adaptor rings, allow you to use filters and accessories that are not the same size as your cameras lens. Lenses and filters come in a large range of types andsizes and unfortunately they don't always fit together correctly.F ortunately 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. The step up rings screws onto your lenses threading and provided a larger thread with you can then attach other elements included 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 adaptor ring that you can find as these will keep the filter close to the lens.

If it is a Sony E PZ 16-50mm lens, in BH I can see it states: "Front: 40.5 mm", which is not either in the step-up measures included (37-49, 49-52, 52-55, 55-58, 58-62, 62-67,67-72, 72-77, 77-82mm). nor in the step-down ones(49-37, 52-49, 58-55, 55-52, 62-58, 67-62,72-67, 77-72, 82-77mm ). According to these specifications, I would say that it will not be useful for this lens. But if you can wait for other -better- explanations, perhaps it is.For all my filters (ND faders, UV, etc.) adapting to different lenses, this kit is ever so useful. But the threads in my lenses are among the ones listed here. Sorry and good luck. Ana. **Q: Can the nano-x magnetic filters be magnetically attached to the rings?** A: ( YES ) Ok say you have a 82mm Glass & you are wanting to put a 37mm magnetic filter on your 82mm Glass. They do the same as your nano-x magnetic filter does then you can add UV, or Color filters. One side has a male threads & the other side has female threads & they go on the end of your glass not your camera. I hope this helped you. **Q: Will this work for 18-55mm Nikon d3000?** A: I have a 18-55 Canon T6I and work perfect **Q: My camera has a 46mm filter diameter and i want to buy a 43mm fisheye. Will these spacers help me ?** A: Hi, this filter adapter rings doesn't support fisheye, thanks. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good product *by S***K on 7 July 2026* Nice ### ⭐⭐⭐⭐⭐ Great *by M***I on 16 April 2025* Great ### ⭐⭐⭐⭐⭐ Good price, good quality *by N***Z on 25 March 2026* I’ve been using these filter rings across all my lenses, and honestly, they exceeded my expectations.
