NiSi Brass Pro 40.5-52mm Step Up Ring

The NiSi Brass Pro 40.5-52mm Step Up Ring allows you to use 52mm filters on any lens with a 40.5mm filter thread, expanding your filter system without duplicating your collection. Machined from durable brass alloy, the ring is engineered to prevent jamming and binding – resisting cross-threading and thermal expansion so it attaches and removes cleanly in any environment. Knurled sides provide a confident grip, while an anti-reflective treatment on the inside of the frame minimises internal reflections that could otherwise affect image quality. A matte black finish keeps things discreet and flare-free.
