I have used ND grad filters for years on my SLR and DSLR cameras. I love scenery photography as opposed to portrait so always looking to sort out the difference in the light between the horizon etc. I live near the sea les that 300m away and walk along the cliffs regularly and don't take my DSLR with me when walking the dogs but always have my iPhone so any unexpected scenes are normally captured using the iPhone. This ND grad filter will come in useful. It fits over the lenses of my iPhone and helps sort out the difference in the light. Once clipped on it is easy to rotate the bezel to the setting you want using your finger. You have to ensure that you do not go past each of the stops or you will get leakage. SO my advise is to check before shooting that you are at the required stop. The other great thing about this filter is that it unscrews from the clip holder and can be screwed onto my 52mm lenses..Bonus... All in all this is a great little filter that I will carry around with me when out walking the dogs. We have a dog walking bag which has Poo Bags and drinking water etc so it sits in the side pocket of the bag in its case. so it is always there if we get a lovely sunset or something really nice to photograph on the sea or beach.. Get little gadget well worth the money highly recommended... As soon as we get anything really nice I will update this with the images...

Hello dear readers,

First of all, I would like to tell you that this product was provided to me free of charge. However, this is not taken into account in my review. I am sharing my "unfiltered" impressions with you. :-)

I tried the filter on my iPhone 15 Pro Max. It is child's play to change the exposure using the rotating mechanism.

As already mentioned here, the filter fits perfectly over the camera lenses, provided there is no cell phone case installed.

Conclusion: Recommended for ambitious iPhone photographers. Price is reasonable given the really outstanding workmanship.

(Price at the time of the test: € 27.49 minus 20% coupon from the promotion)

A special case, a filter body, a mounting clip, a strap to prevent loss, and a cleaning cloth are all included in the set. It's light and easy to carry around. A lost strap is fine, but it might get in the way when shooting. I removed it the second time I used it (lol) It's clip-on, so it's easy to install. If you use this, you can suppress reflections on glass, etc., and when shooting in places with bright sunlight. It is recommended for those who use smartphones to take good photos, and those who want to take filters a notch higher.

Review of "K&F Concept 67mm Magnetic Variable ND2-32 Filter (1-5 Stop) Set for Phone Lens Camera Mount Comaptible with iPhone 15 14 13 12 11 Series, Magnetic Neutral Density with Filter Holder" currently at £49.99:

I used this with my Samsung S20FE phone and it fit well even with case on. The filter is 67mm and fits over all the cameras on my phone easily. It has a nice smooth action for adjusting the ND level. It has a magnetic clip for the lens which is nice, but I would have liked a standard screw mount so other filters could be used.

It is quite expensive for what it is, especially as I can't attach other standard 67mm filters to it, but it does its job well so I can't really mark it down.

This magnetic phone lens filter clip comes in its own storage case,
It’s appears to be made very well, no plasticy parts all metal.
The ND filter density is variable from ND2- ND32 so there is a fair amount of scope.
Other styles of magnetic filters are made by this manufacturer so this makes this a very versatile kit.
The fitting of the clip doesn’t fit that well to my phone case, now this might be down to the style of case I have, (see photo) when I removed the case and attached the clip it fitted like a glove.
I might purchase a cheap phone skin to see if clip fits as it should, if it does I’m gonna buy the CPL filter for this clip.

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.

It's a product that simply fits a camera filter into a smartphone, but if it's a 67mm filter, you can use it interchangeably, and it's a photography item that's not easy to underestimate. The effects of the CPL filter included with this product are also perfect, so you can shoot a notch higher even with a smartphone. If you like photography but feel like carrying a mirrorless camera is dull these days, I think this is an item you can really enjoy! Just like I was.

This is a set of the Nano-K series CPL filter, which is an introductory K&F Concept filter, and a smartphone clip. Previously, was used, but the filter itself is the same as that, and the clip structure seems more sophisticated (this product opens in parallel, but the conventional product opens like a clothespin). Also, the quality of the case has been improved, and a strap is now included. The CPL filter is a basic model that is not coated to be waterproof or scratch-resistant, but the effects of polarized light can be clearly felt. The rotation of the ring is slightly heavy, and there is almost no unintended shift, and I personally like the adjustment. Although the clip has been improved from conventional products, frankly speaking, the feeling of use hasn't changed much. The maximum width between the receiving side and the filter side of the clip was about 14 mm, so be careful when wearing a smartphone with a thickness higher than that, a smartphone with a protruding lens unit, or a thick case. Also, it's not that compatible with smartphones where the lens unit is extremely close to the edge or smartphones that use a camera bar with a full width, such as the Google Pixel 6 to 8 series (it can be used, but it is at a level where you need to be careful about the direction you wear it, etc.). The case looks pretty good and has pretty good protection, but personally I wanted to attach the strap to this case instead of a clip. Considering that [ASIN: B0DZ1R5KWK filter alone] is sold for around 2.5,000 yen, it's quite a bargain that comes with a smartphone clip and carrying case for an additional 500 yen. It's limited to those using a 67mm diameter camera lens, but it would also be helpful to be able to reuse it. However, as pointed out in the review of the filter alone, the protrusion of the filter frame is low, and the lens cap is not good. If you are considering using it in combination with a cap, you may want to consider it carefully.

Purchasing the K&F Concept Universal Cell Phone Camera Lens Set was an excellent decision - I was absolutely thrilled with both the quality and the numerous options. My iPhone photography has taken this experience to a whole new level.

Excellent workmanship:
The lenses and filters are made of high-quality materials and have a very robust feel. The workmanship is of the highest quality and the design looks professional. I am confident that this set will last a very long time.

The set contains a versatile ND2-ND400 filter with a diameter of 52mm, which adapts ideally to different lighting situations. With this filter I can control the exposure precisely and achieve creative effects that would not be possible with the standard camera app.

Easy to use:
It is child's play to attach the lenses and filters to my iPhone. The attachment is secure and stable, without any wobbling or loosening. Handling is self-explanatory and does not require any complicated configurations. It is particularly pleasant to use because you can just put it on and get started.

Improved image quality:
By using this lens set, I have noticed a significant improvement in the image quality of my photos. The shots are characterized by their clarity, richness of detail and professional quality. I am particularly impressed by the results in difficult lighting conditions such as sunrises or sunsets.

Perfect for creative photography:
This set opens up numerous new options for taking creative photos with your iPhone. If I want to control the exposure precisely, the variable ND filter is extremely helpful for long exposures and videos. It is great fun to try out the different effects.

I consider this set to be indispensable for anyone who really wants to take serious photos with their cell phone. An excellent product deserves five stars!

It is a convenient adapter when you want to use a PL filter with a smartphone. It's a first aid measure, so it's not a single-lens reflex camera, but it can be effective as needed. Since the filter frame and filter are separate, others can also be used.
