The K&F Concept magnetic step-up ring adapter 72-82 mm enables seamless compatibility between camera lenses and filters of different thread sizes. This precision-engineered adapter converts 72 mm filter threads to accommodate 82 mm filters, thereby expanding creative possibilities for photographers. Made from durable aluminum alloy with a hard-anodized finish, the adapter offers reliable performance at a minimal weight of approximately 15 grams. The magnetic connection system allows for quick filter changes without the risk of cross-threading, with strong neodymium magnets securely holding filters in place. With an outer diameter of 72 mm and an inner diameter of 82 mm, the step-up ring ensures precise optical alignment to prevent vignetting or loss of image quality. The black anodized surface reduces light reflections and provides corrosion resistance for long-lasting durability. This adapter is compatible with various types of lens filters, including polarizing filters, neutral density filters, and UV filters from multiple manufacturers. The ribbed edge design allows for easy mounting and dismounting without tools, making it practical for field use. With a manufacturing tolerance of 0.1 mm precision, the adapter ensures tight seals against dust and moisture ingress. The product comes with a protective storage pouch to prevent scratches during transport. Ideal for photographers who need filter size flexibility across different lens systems, this step-up ring adapter offers a practical solution to expand filter compatibility without the need to invest in duplicate filter sets.
