So I took these photos with my iPhone 13 Pro Max. The first photo is with no filter and then progresses from ND2 to ND32. I did not further alter these photos in anyway, it is just what my camera automatically adjusts to. I do think the colors and details are a bit more vibrant in the photos with the filters.

What I also love about this set of filters is that the design works with a case. I have a case on my phone and I did not have to take my case off to use this. The magnetic design is also great if you want to be able to take off or put on the filter really fast. I've seen some designs where you have a separate filter for each ND, this is just all in one.

Whilst my main camera is an iPhone 15 Pro Max which I use with a cage that has dedicated mounting for filters, I occasionally like to take my iPhone SE2022 for an airing so ordered this to allow some control over light when shooting.
Unfortunately it seems the iPhone is far too small to allow the mount to clamp on without a relatively thick case, something I prefer not to use as I like the tiny form factor of the phone.

Fortunately ny wife, who is also a photographer, was more than happy to claim this for herself and she had no such issues attaching it to her POCO.

The filter performs as one would expect a K&F product to, no visible vignetting or X in use across the various stops.

I used this with my iPhone 15 Pro Max, and it's such a fun little gadget for exploring the world around you. The magnification is impressive for its size!
I took a zoomed-out shot of a chair and then zoomed in close, and you can really see all the fine details.
It seems like it would be a great tool for checking out jewelry too. I let my son use it, and he had a blast walking around and finding things to examine up close. The built-in light is a nice touch, and you can adjust the intensity, color, and warmth of the light, which is super handy.
Overall, I’d definitely recommend it! The manual is also clear and shows you exactly how to line it up with your phone.

Very good filter system with the most common filters you need. I use this on an iPhone 15 Pro Max using a filter holder for taking pictures and filming. Thanks to the excellent magnetic adhesion, the filters sit firmly on the holder, but are still easy to change in seconds. The image quality is not negatively affected by the filters and is fantastic overall. The price-performance ratio, especially in the set, is great.

Great quality and fits my iPhone 14 pro.

I ordered this polarizing filter for my iPhone 14 Pro Max and I'm happy with it. The clamp fits well, even with a thick case. The cutout prevents light from coming in from behind - a clever solution. The polarizing filter works as expected, especially with glass fronts. The magnetic system is convenient, but makes rotating it a bit tricky. The results are impressive, as can be seen in the attached video. However, the effect is different for different reflections. As a complement to an ND filter, it is very useful. Overall, a solid product for smartphone photography enthusiasts that noticeably improves image quality. There are small weaknesses, but the advantages clearly outweigh them.
