NiSi Brass Pro 67-82mm Step Up Ring

The NiSi Brass Pro 67-82mm Step Up Ring is a precision-engineered adapter that allows photographers to use 82mm threaded filters on lenses with 67mm standard filter threads. Constructed from a durable brass alloy, this frame is designed to be significantly more robust than traditional aluminum rings. The use of brass specifically prevents the common issues of binding and jamming, ensuring that the ring is always easy to remove and providing a reliable connection for your high-end optics.

To ensure professional-level image quality, the ring features a matte black finish and a specialized anti-reflective treatment on the inside of the frame to minimize unwanted reflections. This design helps maintain high contrast and clarity by preventing stray light from bouncing between the lens and the filter. Additionally, the frame is designed with knurled sides for an easier, more secure grip, allowing for quick and confident adjustments even when working in challenging outdoor conditions.

Product Features in Detail

Premium Brass Alloy Frame

Unlike standard step-up rings made from aluminum, the NiSi PRO series is constructed from a durable brass alloy. Brass is significantly more resilient to temperature fluctuations and physical impact, ensuring the ring maintains its perfect circular shape and structural integrity over years of heavy professional use.

Anti-Binding and Jamming Technology

One of the most common frustrations for photographers is a filter becoming "stuck" on a lens. Because brass is a self-lubricating metal, this ring naturally prevents binding and jamming, allowing for a smooth, effortless glide when screwing the adapter on or off, even in humid or cold environments.

Internal Anti-Reflective Treatment

To maintain the highest possible image contrast, the inside of the frame features a specialized anti-reflective treatment. This ensures that stray light doesn't bounce off the metal surface between your lens and the filter, which effectively eliminates internal ghosting and flare.

Enhanced Tactile Knurled Sides

The outer circumference of the ring is designed with deeply knurled sides. This textured surface provides a superior grip, making it easy to tighten or loosen the adapter with precision, even when your hands are wet or you are wearing thick winter gloves.

Matte Black Light-Absorbing Finish

The ring is finished in a high-quality matte black coating. This non-reflective finish is designed to blend perfectly with professional lens barrels while serving the functional purpose of absorbing light, ensuring that the adapter itself never causes unwanted glare in your shots.

Seamless Filter Integration

This adapter allows you to use your large 82mm filters on lenses with a 67mm thread, creating a seamless connection. By standardizing your filter kit to 82mm, you save money and bag space while ensuring that there is zero vignetting, even when using wide-angle lenses.
