Promaster 9791 77-82 升級環

Finally got this to use my 82mm filters on a 77mm lens, and the fit is rock solid with zero wobble or cross-threading. The metal feels sturdy enough for daily bag carry, and it hasn't scratched my lens once.

The threading on this ring is smooth and precise, so my filters screw on without any wobble or cross-threading. It’s a solid metal piece that feels durable in hand, definitely not a cheap plastic ring. Exactly what I needed to use my existing 82mm filters on a new 77mm lens.

Swapped my filters over to this step-up ring and it threads on smoothly without any wobble or cross-threading. The aluminum build feels solid enough that I don't worry about it binding on the lens. It does add a bit of length to the setup, but that's expected and hasn't caused any vignetting.
