Essential lens-to-filter adapter

The 46mm to 49mm CNC Brass Step-Up Ring lets photographers attach 49mm filters to lenses with a 46mm front thread. It is built for shooters who want to standardise on a larger filter size without buying duplicate glass. The brass construction keeps the connection rigid so the filter sits flush every time.

Thread conversion without vignetting

The ring bridges a 3mm diameter difference, which is small enough that most wide-angle lenses will not show corner shading when a single filter is mounted. Stacking multiple filters increases the risk of vignetting, so the practical limit is one filter plus the ring. The precise threads prevent cross-threading that can jam a filter in the field.

Brass body with matte black finish

CNC-machined brass resists the binding and stripped threads common with aluminium rings, and the electroplated coating shrugs off moisture and salt spray. The matte surface eliminates reflections that could flare into the frame at night. Knurled edges give enough grip to remove the ring with cold or wet fingers.

Questions about this item

Will the 46mm to 49mm step-up ring fit securely on my existing 46mm lens threads without wobble?

The CNC-machined brass construction provides precise threading that eliminates wobble and prevents light leaks when attached to 46mm lens threads.

How can I verify the matte black electroplated finish is intact and the threads are clean after I receive the ring?

Inspect the brass surfaces for an even matte black coating without scratches, then rotate the ring onto a 46mm lens to confirm smooth, resistance-free threading.

Does the package include any 49mm filters or only the 46mm to 49mm brass adapter ring?

The box contains only the CNC brass step-up ring; 49mm filters must be purchased separately.
