TOA 130 減焦鏡用 Vari-Ring (TKA31581)

Screwing this vari-ring onto the TOA-130 reducer was effortless, the threads engage perfectly without any wobble. I can already see a noticeable difference in how smoothly I adjust the reduction ratio for framing targets. Exactly what I needed for my imaging train.

Machining is absolutely precise, the threads engage smoothly without any binding. It took the guesswork out of spacing the reducer correctly for my setup.

Finally got my back focus perfect with this vari-ring—the threads are surprisingly smooth for such a precise adjustment piece. Being able to tweak the reducer spacing in tiny increments made a noticeable difference in my subframes.
