ProMaster Step-Up Ring 58mm – 77mm

I was worried about getting a cheap ring that would cross-thread, but this one screws on smoothly and holds tight with no play. The finish is anodized nicely and doesn't scratch my lens barrel.

The threading is so precise that my 77mm filters screw on without any wobble or cross-threading, and the ring itself is thin enough that it doesn't add bulk to the lens. I’ve used it on a few shoots now and it holds tight every time.

Finally got this to use my 77mm circular polarizer on a smaller lens, and the threading is surprisingly smooth for a step-up ring. Snug fit with no wobble, exactly what I needed.
