NiSi step-up ring 58-82mm

A rigid thread-conversion ring made of high-quality brass. Brass series step up rings have a ribbed outer surface for easy filter replacement. The inner surface of the conversion ring is treated with a reflection minimising coating which means that there are no excess reflections in the images.

With the helical rings, you can use a larger filter than the filter thread of the lens. This means you don't need to buy a variable-ND, CPL or even a Natural night filter for every lens.
