NiSi Brass Pro 40.5-49mm Step Up Ring

Use 49mm Filters on a 40.5mm Lens

The NiSi Brass Pro 40.5-49mm Step Up Ring lets you mount 49mm filters onto any lens with a 40.5mm filter thread - a simple way to standardise your filter kit across multiple lenses without buying duplicates in every size. It's a small accessory that makes a big difference to how efficiently you work in the field.

Brass Alloy. Built to Last.

Unlike standard aluminium step-up rings, the NiSi Brass Pro is machined from durable brass alloy, which is far less prone to jamming or binding on lens threads - even after years of regular use. Knurled sides give you a confident grip for easy attachment and removal, while an anti-reflective treatment on the inside of the frame minimises internal reflections that could affect image quality. A matte black finish keeps things clean and professional.
