Bower 46mm/52mm 스텝업 링 - AU4652

Was worried this step-up ring might wobble or add vignetting, but it fits my 46mm lens perfectly and holds my 52mm filter securely. Exactly what I needed for my setup.

Screws on smoothly without any cross-threading, which is a relief because I've had cheap step-up rings bind before. The threading is precise enough that my 52mm polarizer sits flush with no light leaks. Exactly what I needed to use my existing filters on a new lens.

Does exactly what it says—screws into the 46mm thread and gives me a solid 52mm mount for my bigger filters. The threading is smooth and it doesn't add much bulk, though I wish it came with a tiny bit more grip on the outside.
