NiSi Brass Pro 49-77mm 升級環

Finally, a step-up ring that doesn't stick or cross-thread—the brass threads are incredibly smooth and precise. Fits my 49mm lens perfectly and lets me use all my 77mm filters without any wobble. Well worth the price for the build quality alone.

I was tired of buying separate filters for every lens size, and this step-up ring finally solves that. The brass build feels much more solid than the aluminum ones I've used, and it lets me put my 77mm filters on my 49mm lenses without any wobble.

This brass ring threads on smoothly without any of the binding I've had with aluminum ones. The 49-77mm jump lets me use my favorite filters on both my small and big lenses, which saves me from buying duplicates.
