Brass Pro Step-Up Ring 46-49mm

The NiSi Brass Pro Step-Up Ring adapts a 46mm male lens thread to accept 49mm filters and accessories. It is built for photographers who own lenses with different thread diameters and want to standardise on a single filter size.

Brass alloy frame with knurled edges

A robust brass alloy construction resists corrosion and extreme temperatures while preventing the binding common with aluminium threads. Knurled side edges give a secure grip for quick attachment and removal during filter changes.

46mm to 49mm thread conversion

This ring only bridges a 46mm lens thread to a 49mm filter thread; it cannot adapt other diameter combinations. Buyers needing different step-up or step-down sizes must choose another adapter.

Questions about this item

What thread standard does the 46-49mm step-up ring use?

It uses standard circular filter threads with a 46mm male thread on the lens side and a 49mm female thread for filters.

What physical dimensions must my lens and filter have to fit this ring?

Your lens needs a 46mm front thread and the filter or accessory needs a 49mm thread to match the ring.

How do I install the brass step-up ring without cross-threading?

Align the 46mm male thread with the lens, turn gently using the knurled edges until seated, then attach the 49mm filter to the front thread.
