Promaster Stepping Ring - 39mm-52mm

Threads on both ends are cut clean and true, so the filter screws on smoothly without any wobble or cross-threading. It’s a solid little adapter that does exactly what it says, and the step-up in size is barely noticeable once it’s mounted.

The threading is precise and smooth, so attaching my 52mm filter to the 39mm lens took no effort at all. It feels solidly built and doesn’t wobble once tightened, which makes me confident it won’t cause any vignetting.

I needed a 52mm filter to fit on a 39mm lens, and this stepping ring solved it perfectly. The metal feels solid and screws on without any wobble. Only wish the ring was a few dollars cheaper.
