A versatile accessory for photographers, the NiSi Brass Pro 58-77mm Step-Up Ring is designed to facilitate the use of 77mm threaded filters on lenses equipped with 58mm standard filter threads. This precision-engineered ring is crafted from durable brass, ensuring longevity and resistance to wear and tear. The ring's design features knurled sides, which provide a secure grip for effortless attachment and removal. Unlike standard aluminum step-up rings, the NiSi Brass Pro Step-Up Ring is specifically designed to prevent binding and jamming, ensuring smooth operation and ease of use. One of the standout features of this step-up ring is its special anti-reflective felt treatment. Applied to the inside of the frame, this treatment effectively minimizes reflections, making it an ideal choice for long exposure photography.
