フィルタースライダー - 2インチ to 36mm 未マウントフィルターアダプター (SFS-236A)

I was worried about fit, but this ring locks my 36mm filter into the slider perfectly with zero wiggle. The threads are clean and precise, making installation quick. Really solid build for the price.

The threading on this ring is spot-on for the M48 to 36mm conversion—no wobble, no forcing it into the holder. I switched out my old adapter and the filter seats perfectly every time, which makes swapping between narrowband sets way less fiddly.

Finally a step ring that actually mates perfectly with the Starizona slider. The M48 threads are cut cleanly and spin on smooth without any binding. Just what I needed to adapt my 36mm unmounted filters.
