The NiSi Brass Pro 62-67mm Step Up Ring allows you to seamlessly attach 67mm threaded filters to lenses featuring a smaller 62mm filter thread. Machined from high-quality brass, this step-up ring is incredibly durable and highly resistant to binding or cross-threading, ensuring a smooth and secure fit every time you attach or remove it. Its matte black electroplated finish prevents unwanted reflections and light leaks, preserving the optical integrity of your images. This simple yet essential adaptor is a highly cost-effective way to use a single set of larger filters across multiple lenses in your kit.
