Crafted for professional reliability, the NiSi Brass Pro 52-62mm Step Up Ring enables the mounting of 62mm filters onto 52mm lens threads. By utilizing brass instead of aluminium, NiSi ensures a robust frame that maintains its shape and threads smoothly without seizing over time. The exterior is finished with a felt-like matte texture to eliminate internal reflections, providing a secure, tactile grip that is essential for quick filter changes in the field.
