It’s a good step up ring and works fine so long as you stick with 58mm filters. Just, don’t expect it to lift your larger filters above the Beastgrip housing, even with a second step up ring. You still lack ca. ⅛” of clearing the bumps on the side. I got it in hopes that it plus a 58mm to 77mm step up ring would let me use my VND with my standard iPhone lens. It does not.
