NiSi S6 150mm濾鏡支架轉接環 適用於Sigma 14mm f/1.8 DG HSM Art

Finally, no more wrestling with step-up rings that just don't sit right on this specific Sigma lens. The way it locks into the holder is incredibly snug, which gives me confidence it won't vibrate loose during long exposures.

The machining on this ring is so precise that my filters sit perfectly flush with zero light leaks. I was worried about vignetting on such a wide lens, but it's completely gone.

Finally, an adapter ring that fits this lens like it was machined for it — no wobble, no light leaks, just a solid click into place. It makes mounting the 150mm holder system on the Sigma 14mm f/1.8 Art so much less fiddly, and that precision-fit is exactly what I needed for my wide-angle shots.
