About this product

The NiSi Brass Pro 40.5-52mm Step-Up Ring is a precision optical adapter designed to allow the use of 52mm threaded filters on lenses with a 40.5mm filter thread. Crafted from durable brass, it offers long-term reliability and resistance to wear. Its knurled sides provide a secure grip for easy installation and removal, reducing the risk of binding or jamming common with aluminum alternatives. The interior features an anti-reflective felt treatment to minimize lens flare and ghosting. This ring is ideal for photographers seeking a robust, efficient solution for filter compatibility across different lens sizes.
