NiSi Adaptor for Tokina 11-20mm

I was worried about the vignette, but it's barely noticeable in the field and the filter holder locks on perfectly to my Tokina 11-20mm. Makes using my square filters a breeze.

Even with the slight vignette the listing warns about, I’ve had zero trouble using this with my V5 holder on the Tokina 11-20mm—the lock ring is snug and doesn’t wiggle at all. It’s a simple, solid adapter that does exactly what it’s supposed to do.

The adapter ring fits my Tokina 11-20mm securely, no wobble at all, though the slight vignette is noticeable at the widest end—manageable with a quick crop in post.
