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.

The K&F Concept 67mm CPL Filter and phone clip arrived packed in a high quality printed cardboard box bearing the K&F branding.

In the box you get a 67mm CPL filter, a clip for phone mounting, a cleaning cloth and a nice hardshell carrying case.

The clip is listed for being for an iPhone but will fit most modern phones up to 13mm thick where the camera is located in a corner.

Clip is nice and snug on my Samsung Galaxy S23 and there are no problems with alignment of the filter or any apparent vignetting.

The filter rotates smoothly in the holder without being too loose and is a boon for any images where there are a lot of reflective surfaces that need to be controlled.

Good value for a handy kit.

The K&F Concept 67mm MC UV Lens Protection Filter is well made and feels like very good quality. Looks fantastic on my Sony lens and works well making photos look good.

I got my new K&F Concept Clip On 67mm CPL Magnetic Phone Lens Filter Kit today and anxiously opened it to give it a try. My first impression is that this K&F Concept Clip On 67mm CPL Magnetic Phone Lens Filter Kit is a well built camera phone accessory.
It is made of metal, aluminum I think, and is solid. It comes in it's own zippered case with foam packing that speaks of quality too. The nice feature about this K&F Concept Clip On 67mm CPL Magnetic Phone Lens Filter Kit is the magnetic method to attach the filter. The filter itself magnetically snaps into place with a firm grip. There is no concern that the filter may ever just fall off.
The K&F Concept Clip On 67mm CPL Magnetic Phone Lens Filter Kit connects via a thumb screw that tightens onto the camera screen to hold the filter frame secure. This is a bit concerning to me as I would think that if you aren't careful you could over tighten the screw and end up breaking the phone screen.
When I attached the K&F Concept Clip On 67mm CPL Magnetic Phone Lens Filter Kit to my Galaxy S23 Ultra, which has 5 camera lenses, it looks like the filter slightly blocks the bottom camera (Telephoto 1). However, as I switched between the camera zooms and I didn't see/notice any actual blockage of the lens. I will keep an eye on this as I use theK&F Concept Clip On 67mm CPL Magnetic Phone Lens Filter Kit more to see if any thing is ever obstructed by the filter.
The filter lense itself also is well made. It has an aluminum outer ring and fits nicely into the frame and the lens is made of glass that is tinted for the CPL effect.
In all, I give the K&F Concept Clip On 67mm CPL Magnetic Phone Lens Filter Kit a thumbs up, but I do worry about over tightening and cracking my phone screen.

EVERY LENS SHOULD HAVE A UV FILTER FOR IMPACT PROTECTION. NOT THE BEST QUALITY BUT IT WORKS FOR A LENS I WILL ONLY USE 10-15 TIMES A YEAR. CANON R3

review the K&F Concept K-Series 67MM MCUV Pro UV Filter Slim MC UV Protection Filter Ultraviolet Filter, which was kindly provided to me free of charge by Amazon Vine for testing. My opinion is unaffected by this fact, my review reflects my experience with the product. I will get this filter again for money Why? Because it fits my fleet and I have finally found affordable, high-quality protection for my favorite glasses. I have to place the thread very flatly so that it doesn't get caught (no hectic moves; it can be unscrewed calmly but in a relaxed manner). I work with fast lenses and don't see any serious changes when stopping down. There is still one advantage - the sky is a bit bluer in the picture

K&F Concept 1/4 Black Mist Diffusion 67MM Filter

Super cool filter, well made and good quality. The filter can be screwed on cleanly and sits perfectly on my Tamron's 28 75 and 70 180 2.8. The effect is really cool and in combination with the Aputure Accent B7C, Hollywood says hello.

I think the filter is really cool and you can let your creativity run free. The price is also great and super fair.

Best quality filter I had in a while,
