The NiSi Brass Pro 52-58mm Step-Up Ring allows you to use 58mm filters to be used on lenses with a standard 52mm filter thread. You will find a durable brass frame with knurled sides for easier grip. With the NiSi Brass Pro Step-Up Ring made from brass, binding and jamming are prevented, making it easier to remove compared to standard aluminium units.

The NiSi Brass Pro Step-Up Ring features a matte black finish and a special anti-reflective felt treatment on the inside. Especially for shooting long exposures, the felt treatment minimises reflections.
