K\u0026amp;F Concept makes this adapter for photographers who want to use a larger magnetic filter on a lens with the matching smaller front thread. Its magnetic design makes it a link in a magnetic filter setup. That’s the practical job here: it connects the lens and filter. It’s an adapter, not a filter, so its role is to provide the physical connection rather than an image effect. This can help if you have a filter you want to use on a lens with a smaller thread. The important part is matching the lens-side thread to the adapter; the step-up ring is made for a specific size pairing.\u003c\/p\u003e\n\u003ch3\u003eFitting it into your setup\u003c\/h3\u003e\n\u003cp\u003eStart by reading the filter-thread size on the front of your lens, then compare it with the smaller side of the ring. The filter you plan to attach needs to match the larger side. Keeping those two measurements straight makes it easier to choose the right adapter and avoids treating a step-up ring as a universal connector. If you use filters across different lenses, you can keep this ring with the lens whose thread matches it. The ring handles that one size conversion; it doesn’t change the size of the filters themselves.\u003c\/p\u003e\n\u003cdiv class=\"specialist-note\"\u003e\n\u003ch3\u003eSpecialist Note\u003c\/h3\u003e\n\u003cp\u003eOnce the ring is matched to the lens, the setup is straightforward: fit it to the front thread, then attach the magnetic filter. This one converts a 55mm lens thread to an 82mm filter size, so it suits someone who wants to use that larger filter on a lens with the smaller thread. For example, if your 82mm magnetic filter is the one you want to use, match the ring to the lens marked 55mm and make sure the parts seat correctly. The magnetic design is the detail to look for in your filter setup. One limit: it only bridges this specific size pairing, so it won’t solve a mismatch involving different thread sizes.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eProduct: K\u0026amp;F Concept Magnetic Step Up Ring Adapter\u003c\/li\u003e\n\u003cli\u003eType: Step-up ring adapter\u003c\/li\u003e\n\u003cli\u003eDesign: Magnetic\u003c\/li\u003e\n\u003cli\u003eAdapter size: 55-82mm\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"K\u0026F Concept","offers":[{"title":"Default Title","offer_id":57503493652820,"sku":"KF-05.301","price":24.51,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0780\/2493\/3716\/files\/KF-05.301_01.jpg?v=1791566423","url":"https:\/\/www.htf-store.com\/fr\/products\/k-f-concept-magnetic-step-up-ring-adapter-55-82mm","provider":"Hard to Find Camera Store","version":"1.0","type":"link"}
