NiSi Brass Pro 49-77mm Step-Up Ring

Allows 77mm threaded filters to be used on lenses with 49mm standard filter threads. Features a durable brass frame with knurled sides for easier grip. Designed to prevent binding and jamming, making it easier to remove than standard aluminium step-up rings. Has an anti-reflective treatment inside the frame to minimize reflections and a matte black finish. The anti-reflective treatment makes the ring suitable for long exposures.
