NiSi NIP-STP-46-52 PRO 46-52mm Aluminum Step-Up Ring

The NiSi PRO 46-52mm Aluminum Step-Up Ring is a precision-machined adapter that bridges the gap between 46mm lens filter threads and larger 52mm filters. For photographers who own multiple lenses with varying thread sizes, step-up rings like this one offer a cost-effective solution: buy your filters in one larger size and use adapters to fit them across your entire lens collection. The NiSi PRO ring makes this approach practical with its compact, featherweight design that slips easily into a pocket or accessory pouch.

Built from anodized aluminum alloy, the ring resists corrosion from moisture and outdoor elements while maintaining precise thread tolerances for a secure, smooth fit on both the lens and filter. The matte black anodized interior finish is more than cosmetic — it actively suppresses stray light and internal reflections that could otherwise introduce flare or reduce contrast in your images. The stackable design means you can combine multiple rings if needed, offering flexibility as your lens collection grows.
