NiSi Brass Pro 52-67mm 升級轉接環

The finish is perfectly smooth—no wobble at all when mounting my 67mm CPL. It’s lightweight enough that it doesn’t throw off the balance on my travel lens. Exactly what I needed for sharing filters across two different setups.

The threading is incredibly smooth—no cross-threading or wobble when I screw my 67mm ND filter onto my 52mm lens. It’s solid brass, so it doesn’t bind like those cheap aluminum ones I used before. Makes swapping filters between lenses feel effortless.

This brass step-up ring fits perfectly on my 52mm lens without any wobble, and the 67mm threads are smooth when attaching my filters. It’s solid and precise, which makes swapping between lenses much easier.
