NiSi 77-82mm Brass Step Up Ring

The NiSi Brass Pro 77-82mm Step Up Ring is a premium solution for photographers looking to adapt 82mm threaded filters to lenses with 77mm filter threads. Built with a heavy-duty brass frame, this ring is specifically designed to prevent the binding and jamming often associated with cheaper aluminum adapters, ensuring smooth installation and removal. The frame also features knurled sides, providing a superior tactile grip that makes it much easier to handle in the field, even when wearing gloves.

To ensure the highest image quality, the interior of the ring features a specialized anti-reflective felt treatment combined with a matte black finish. This unique design effectively minimizes internal reflections and stray light, making it an ideal companion for high-contrast scenes and long-exposure photography. By maintaining a clean light path, the NiSi Brass Pro helps preserve the integrity of your images while offering the durability of a professional-grade brass alloy construction.

Product Features in Detail

Durable Brass Alloy Construction

Unlike common aluminum rings that can warp or expand with temperature changes, the NiSi Brass Pro is forged from a heavy-duty brass alloy. This material is significantly more robust and retains its shape under stress, ensuring that the threads remain perfectly circular and functional over years of professional use.

Anti-Binding and Jamming Design

Brass is a self-lubricating material compared to aluminum, which means this ring effectively prevents binding and jamming. This is a critical advantage for photographers who have experienced the frustration of a filter becoming "welded" to their lens, allowing for effortless mounting and removal in any environment.

Specialized Anti-Reflective Felt Treatment

The interior of the frame is lined with a unique anti-reflective felt treatment. This is a premium feature rarely found in step-up rings; it absorbs stray light and kills internal ghosts and flares that can occur when light bounces between the lens element and the filter glass.

Enhanced Knurled Side Grips

The outer edge of the ring features deep knurled texturing, providing a high-friction surface for your fingers. This ergonomic design is especially useful when working in cold, wet conditions or while wearing gloves, allowing you to tighten or loosen the ring with total confidence.

Optimized for Long Exposures

The combination of the matte black finish and the internal felt lining makes this the perfect companion for long-exposure photography. By eliminating light leaks and internal reflections, it ensures that your 10-stop or 15-stop ND filters perform at their peak, maintaining deep blacks and high contrast.

Matte Black Aesthetic and Function

Finished in a professional matte black coating, the ring is designed to blend seamlessly with high-end cinema and photography lenses. This finish isn't just for looks; it further aids in light absorption, ensuring that the ring itself never becomes a source of glare or unwanted light artifacts in your frame.
