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.

I have a cage for my iPhone 15 Pro Max and 14 Pro so am able to fit screw on filters but my lowly but much loved SE has no such luxury.
This meets that need with the added bonus that I also have a whole bunch of lenses that take a 52mm thread filter too

very good

This is a well built backpack camera case. Lots of room and greasy protection for your expressive gear.

Excellent product for my daughters new MacBook Pro 15" ready for university this year. Lots of storage space, hidden zipper pocket for MacBook and coded protection - for the money it's a worthwhile excellent product, very happy

This filter works well with several of my Canon lenses. It feels very well made and I am confident that it is added protection for my lens glass as well. I appreciate it comes with a sturdy case that can be used when not on my lenses.
