Great quality build, the magnetic is super strong. It also fits perfectly.

I didn't know if I would like this attached to my phone but it actually works well. When I first got it I mounted a CPL filter on it and got a few images in my garden. I used it mid day or so when I thought the filter would be of some use. It's about a 3 stop difference and it produced a nice shot on my IPhone 14 PMx. So if you are take images on your phone this filter carriage vworks nicely. Just make sure to have or get the size filters you need as the mount will serve only the size you order.

This might be the best mobile filter solution that I have found to date. Most of the other options require a special case or use a clip-on mount. This utilizes MagSafe, which I love and use for several other accessories. The magnet is strong and the build quality is great. Even though it doesn't fit flush on the phone when I leave my case on, the magnet is so strong, that I have no problem still using it. I think this will be a good solution for ND filters.

This product is fantastic for enhancing iPhone photography, as it fits my filters perfectly and allows the use of professional photographic filters. It works well across all cameras in the triple array, which is a big plus for versatility. While I haven't tested it with my DJI Gimbal yet, I'm optimistic about its compatibility.In terms of value, the construction is solid and sturdy, which is reassuring given the price. The magnet is impressively strong, securely adhering to the MagSafe on my iPhone 15 Pro Max, so everything stays put during use.Overall, if you're looking to boost your iPhone's photography capabilities, this is a great investment. Highly recommended for anyone serious about mobile photography!

“Turns Your iPhone into a Full-Blown Cinema Rig—Almost”I slapped the K&F Concept 6.7″ magnetic filter adapter onto my iPhone 15 Pro Max faster than you can say “cinephile,” and suddenly I was shooting like a one-man studio. The CNC-machined aluminum ring feels rock-solid, and the neodymium magnets grip 67 mm threaded filters with the tenacity of a barnacle on a hull. Whether I clipped on a CPL for moody cityscapes or a 10-stop ND for those milky-water waterfall shots, the adapter never once wobbled or let stray light creep in.What I Loved:Universal Fit: Compatible with every iPhone 12–16 Pro, Plus, and Max model I tested, and even works on my partner’s older iPhone for quick filter swaps.Smooth Magnetic Action: One-hand filter changes—kiss those fumbling thread mounts goodbye.Low-Profile Design: At just 6.7 mm thick, it barely adds any bulk, so your phone still slides into pockets and mounts like normal.Minor Quibbles:Filter Not Included: You’ll need to already own 67 mm filters (or budget for them) to get started.Lens Alignment: If you’re shooting extreme wide-angle, the adapter can cast a subtle vignette—easily fixable in post, but worth noting.All told, this adapter is a game-changer for mobile shooters who already own standard 67 mm glass. It won’t replace a dedicated cinema lens, but for on-the-fly filter magic with your iPhone, it’s the closest thing to cinematic sorcery you’ll find in your pocket.

The clip lines up cleanly on my iPhone 16 Pro Max and lets me swap ND or CPL filters in seconds—huge win for run-and-gun shooting. Optical quality is as good as my K&F camera glass, and the cold-shoe on top is handy for a mic. Downsides: the magnetic coupling is fine for lightweight filters but felt shaky once I stacked a heavier glass VND; a small bump popped it off. If you shoot handheld or in wind, keep a hand on the filter. Overall, a fast, compact way to add real filtration to a phone rig.

Works with Samsung S23 Ultra. I have a Quadlock mag case and this snaps on really securely. Covers one lens, not sure what it's used for as main camera, video all work even zooming wide to telephoto. So not a problem. Did find an S23 version but it wasn't K&F. Well made, good finish highly recommend.

Works good, wish it fit around my case though. Case off and works perfectly with lenses set
