The NiSi Brass Pro 46-49mm Step Up Ring is a precision filter adapter that enables the use of 49mm threaded filters on lenses with 46mm standard filter threads. Constructed from durable brass alloy with a matte black finish, this step-up ring features knurled sides for improved grip and an internal anti-reflective felt treatment to minimise unwanted reflections. The brass construction prevents binding and jamming, making it significantly easier to remove compared to standard aluminium alternatives, whilst the anti-reflective coating makes it ideal for long exposure photography.
