濾鏡滑板 - 2" 轉 1.25" 濾鏡轉接器 (SFS-2125A)

I was worried about adding more bulk to my filter train, but this step ring truly is zero profile—it sits flush and adds no extra height. Works perfectly with my 2" to 1.25" setup, and the threads are smooth without any wobble. Finally got clean flats without having to re-space everything.

The threads engaged perfectly with my existing filter slider, no wobble at all. Finally a step ring that actually stays put when I swap filters in the field.

I was worried about adding height to my filter train, but this adapter threads on perfectly flush with the M48 connection. It locks onto the Filter Slider securely without any wobble during long exposures.
