Crafted from high-quality brass with a non-slip textured finish, the NiSi Brass Pro 52-67mm Step Up Ring allows you to mount 67mm threaded filters onto lenses with a 52mm front diameter. The use of brass prevents the binding and sticking often associated with aluminium rings, ensuring smooth attachment and removal even in fluctuating temperatures. This precision-engineered accessory is a cost-effective solution for photographers who want to use a single set of large filters across multiple lenses without compromising on build quality or durability.
