NiSi Brass Pro Step Up Ring 40.5mm to 52mm

Description

Overview

The NiSi Brass Pro 40.5-52mm Step Up Ring is a precision-machined adapter that allows photographers to use 52mm threaded filters on lenses with a 40.5mm filter thread. Part of the NiSi Brass Pro Step Up Ring series, this adapter is designed for photographers who want a more reliable, better-performing alternative to standard aluminium step up rings—particularly when shooting long exposures, landscape photography, or any situation where secure filter attachment and reflection control matter.

Whether you are building out a filter system across multiple lenses or simply need to adapt a larger filter to a smaller lens thread, this step up ring offers a practical, well-engineered solution that fits cleanly into a NiSi filter workflow.

Experience & Benefits

One of the most common frustrations with standard aluminium step up rings is binding—where the ring seizes onto the lens or filter, making removal difficult and sometimes damaging threads in the process. The NiSi Brass Pro ring addresses this directly. Brass construction naturally resists the binding and jamming that can occur with aluminium rings, making filter changes and ring removal noticeably smoother and more reliable in the field.

Grip and handling are also improved through the knurled outer edge of the frame. When working with gloves, in cold conditions, or simply when fingers are not perfectly dry, the textured surface gives you confident purchase on the ring without needing to over-tighten to compensate for slipping.

For photographers focused on long exposure photography—whether shooting seascapes, waterfalls, or architecture at night—internal reflections inside a filter adapter can subtly degrade image quality. The NiSi Brass Pro ring features a special anti-reflective treatment on the interior of the frame, combined with a matte black finish, to minimize stray light and internal reflections that could otherwise affect image contrast or introduce unwanted flare during long exposures.

The matte black finish also reduces the visibility of the ring itself within the optical path, keeping the setup clean and professional. These details reflect the broader NiSi approach to filter accessories: small components engineered with the same attention to optical integrity as the filters themselves.

Practical Details

This ring steps up from a 40.5mm lens filter thread to a 52mm filter thread, making it straightforward to use a single set of 52mm circular filters—such as CPL, ND, UV, or black mist filters—across lenses with the smaller 40.5mm thread. This is a practical way to reduce the number of duplicate filters needed when working across a kit with lenses of different thread sizes.

Installation is simple: the ring threads onto the lens at the 40.5mm end, and your 52mm filter threads onto the ring as it normally would onto a lens. The brass construction ensures smooth threading in both directions, and the knurled sides make it easy to seat and remove the ring without tools. No special adapters or additional hardware are required.

For photographers already using NiSi circular filters or building toward a NiSi filter system, the Brass Pro step up ring is a reliable way to extend compatibility across lenses without compromising the optical or handling quality of the setup. It is particularly well suited for travel photographers and landscape shooters who work with compact or older lenses that carry smaller filter threads.
