This K&F Concept Clip-On 67mm CPL Magnetic Phone Lens Filter Kit is very easy to use and fits over my iPhone camera perfectly. However, it may not work for other phones with different camera configurations. The filter does help significantly reduce harsh reflections, but I’m not very impressed with its ability to deepen and enrich blue skies. It comes in a nice protective case with a microfiber lens wipe as well. Unfortunately, this is not a rotating circular polarizer like the ones they make for DSLR cameras. On the plus side, it does have a magnetic mount, so it’s easy to adjust and swap out with other filters as needed.

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.

This ND filter was developed specifically for the iPhone. This should be taken into account, otherwise the verdict will probably not be so favorable. The special thing about it is that this ND filter with its filter ring completely encloses the camera module of the newer iPhones. The actual filter then lies directly on the lenses and sits really well.

Unfortunately, this doesn't work with a cell phone case that has a camera protector. Then the camera module becomes too big and the filter no longer fits over it.

The whole thing is held in place with a fairly tight clamp, which of course then covers part of the display. But in my opinion that's not particularly important.

The filter can be adjusted from filter strength ND2 to ND400 by simply turning it. The whole thing is done with a quarter turn, so all levels are pretty close together, so you should turn slowly. There is a 10-level division on the ring, but it can still be adjusted continuously. The filter does not always have the same effect on all three lenses. With the ultra-wide angle of the iPhone 14pro, for example, you can get the filter ring in the picture with some settings. In some settings you notice a slightly stronger vignetting. You have to try it out a bit, but you can get the hang of it quickly.

Who needs something like that? Certainly no one who doesn't know straight away what an ND filter does. The product is aimed more at photographers who want to get even more out of the iPhone and, especially in bright light, still want to use long shutter speeds. To do this, you would have to delve a little deeper into the subject. There are numerous, very good YouTube videos on the subject...

I think it's really great that the filter holder or clamp with a 52mm thread can also accommodate other filters. A polarizing filter or graduated filter would be exciting here for different effects.

In any case, I am very happy with this ND filter, even if I probably won't use it that often. I tend to take the photos or videos that can be produced with it with a system camera. But if you're travelling light or want to experiment with iPhone photography, this is the right choice. The price is unbeatable for this great quality.

nice indicator so you know what level it is (min to max)
+ well thought design
+ easy to use
+ changes photos/videos a bit
+ slim, small and light
+ can be used with an iPhone in the case (but it's better to use it without a case on an iPhone)
+ microfiber cloth in the bundle, so you can clean it every time

- part of it stays on the screen and it may be a bit annoying

I bought this camera for a cruise to the Caribbean. I didn't want to worry about using a waterproof case for my cell phone. This really did the trick! Takes beautiful underwater video and pictures. I was pleasantly surprised by the quality. Battery life was great, as well. Very easy to use. My only complaint is that the screen easily collects fingerprints. Overall, I love it!

This mic took my videos to a level I didn't know was possible. I'm not sure how I allowed my self to record with my iPhone mic or my pc mic. The best part is not being stuck to one place in order to be heard. Instead I can walk where ever I like as close or as far from the camera as I like and I'm still heard the exact same way since it's wireless.

I was a bit intimidated by all the stuff that came with it thinking it would be tough to figure out but It was SOO EASY to setup on my DSLR and even easier for my phone. It's literally plug and play, I didn't have to change any settings anywhere. I love that it comes with 2 mics incase one dies or if I have a friend in the video with me. The charging case is also a big plus. To be fully honest, I fell in love with this before buying it and now that I have it and saw that it exceeded my expectations It has given me the confidence to make content!

Pros:
Flexibility
Compatible with both iPhone (lightning port) and android (USB-C)
Works with DSLR
Long battery life
Included filters
2 Mics
Charging case
came with a little carrying bag

Cons:
I only have one and want another

I ordered the magnetic phone camera lens kit for my iPhone because I like to take videos and photos. The product quality is very high and it is easy to install.

The kit works exactly as expected and delivers much better results. I can only recommend it.

I took a punt that this would fit on either an iPhone XR or a second generation SE (neither model being mentioned) and am glad that I did, as it attaches without issue to both models. The filter attaches by means of a strong clip that doesn't cause any issues for the device - but might not fit at the same time as a case. The adjustable ring moves readily and there are clear markings on it for start point and maximum. This was supplied boxed, with a neat, reusable, protective plastic storage case and accompanied by a useful litter microfibre cleaning cloth.
