Promaster 5047 58-62mm opstapring

The threading is machined perfectly—my filter screwed on smoothly without any wobble or cross-threading issues. It's a solid, lightweight metal ring that feels durable enough for regular use in my kit. Exactly what I needed to adapt my filters to a different lens thread.

I needed a step-up ring for my 72mm filters to fit a 62mm lens, and this one threads on smoothly without any cross-threading or wobble. The brass construction feels solid and has held up well in my bag.

The threading is precise and screws on smoothly without any cross-threading issues. I’ve used it to mount a 62mm polarizer on my 58mm lens, and it holds firmly with no light leaks. Just a slight step up in thickness compared to a filter alone, but still perfectly functional.
