Promaster Stepping Ring - 77mm-82mm

I was worried about vignetting with a step-up ring, but this one is thin enough that I haven't seen any issues even with my wide-angle lens. The threading is smooth and tight, no wobble at all.

This step-up ring connects my 77mm lenses to my new 82mm filters perfectly, no annoying cross-threading at all. The anodized finish feels solid and lightweight in hand.

The threads are machined so smoothly that the 77mm lens screws on without any wobble, and the step-up to 82mm feels solid when I mount my larger ND filter. It's a small piece of metal, but it does exactly what it's supposed to do on every shoot so far.
