K&F CONCEPT 67mm Press-on CPL Phone Lens Filter Kit, Polarizing Filter Compatible with iPhone 17/16/15/14/13/12 Standard, 16/15/14/13/12 Pro/Pro Max, 67mm Threaded Filters

I was surprised by this lens filter! The quality is exceptional for the category (typically lens filters are on the flimsy side), and it improves color accuracy and reduces the glare in photos dramatically. I currently shoot on the iPhone 17 Pro Max, and the color science of typically saturates yellows heavily. This filter completely changed the photographic ambiance, and cooled down yellows indoors. In outdoor lighting, it helped to improve color accuracy and the sharpness of blues.There is not magnetic component to this lens, however the fit at 67mm I believe is necessary for the new line of iPhones. I found the fit to be perfect in the large size, and would recommend this if you have a newer phone model as well. The attachment mechanism is also slick.Overall, the value for the money is absolutely there, because of the benefits from the lens filter paying for itself in color-accurate photos on mobile. If you are on the fence? You won't regret it.

This is a CPL filter that is set so that it covers a smartphone camera. The filter used was the NANO-K Series 67mm. (Since the filter has a replaceable structure, other filters could also be attached) Reflections can be removed thoroughly, making it even more beautiful to take pictures. By rotating the filter when shooting a container with strong plastic reflection, it became quite calm. (The reflective part in the video has weakened) It comes with a case that fits the filter as it is for portable use, and the lens surface can also be properly protected.

Needed to use an app (used Halide) to manually control iPhone camera settings. The default camera app kept trying to correct the ND filter changes. Other than that, it's great!

Overall this is an excellent higher-end accessory to improve photo and video. It does exactly what a polarizer needs to do.
Fits well on both an iPhone 12 Pro and an iPhone 15 Pro. It's rather heavy so feels less balanced on the smaller phone.
Nice carrying case - it isn't something you'd leave on the phone all the time. Because it's a 67mm size, it doesn't create vignetting when using the ultra wide lens.
It's a bit stiff on rotation, but may smooth out over time. Overall glad to have it for upgraded personal and professional (I handle a lot of content creation in my job) use.

The clip-on makes it difficult to attach and its easy to accidentally detach when adjusting the filter itself. The included case is a nice addition to protect the filter from scratches and small drops. The polarizing effect of the filter I did not find to be as effective as I expected I tried to take some pictures of a turned off TV screen and the effect was not what I expected regardless to what I set the filter.

First I need to say I only take photos with my phone and have no experience with cameras, special lenses or photography. This will be a review based on my limited experience.I found this lens to be quite helpful to get details for things. I want a photo so I can refer to it when I’m painting that image.I drove around to find things to take pictures of and liked this little area. The day was very sunny (and cold!). I understand sunny days to be one of the conditions the lens is most helpful with. Boy was it ever.I have included 2 sets of photos to show the difference with and without the lens.First of all, the lens comes packaged up nicely. You have to screw the lens onto the attachment piece that easily clipped onto my iPhone 14 with a bulky otterbox shock protector. I was pleased that I didn’t have to take my phone out of that to have it fit.The first 2 photos I had my camera screen zoomed to the max! I used the lens with the first photo. I didn’t notice a lot of difference between the photos as far as detail. I did see a color change with the lens.I decided to take the next two photos of a smaller mountain that was closer to me and the suns position. I zoomed in about halfway. I love that the lens made it so that I could see everything with much more detail. This is exactly what I was hoping for. Again the lens is used in the first photo. The sun was so bright day and I believe the sun glare keeps you from seeing that in the photo without the lens. This is just what I was looking for. To me the detail and color are great! I am excited to get out and try it in different scenarios.I do think the $21 and some change that this lens is priced at is a good value. Especially for someone like myself who has no idea what I’m doing and wants to experiment with lenses.What a great way to get a closer inspection of our beautiful world!

I'm an advanced hobbyist. I have Canon gear up to and including L lenses. I have a Samsung S22 Ultra for a phone. Is a phone camera ever going to replace a DSLR? No, but you always have a phone in your pocket when the big camera can be nowhere to be had. A polarizer is a pretty essential piece of gear for bringing out skies, pulling a mountain out of the distance from the haze, making water deep blue instead of reflective, making the color of flowers pop, and the list goes on. That's the one thing that's always lacking on a phone cam - a polarizer. I'm glad I got the 67mm because with the layout of the lenses on the S22 Ultra, (the newest Samsung Ultra phones have the same lens layout) a 58 millimeter wouldn't work. Comes in a nice hard zipper pouch, cleaning cloth, and a short bright orange lanyard. The filter, like most quality filters, has etched legends around its edge, and it's very smooth turning and has no distortions that I can find. I have dealt with cheap polarizers and they can have issues, this one has none of that. The holder is great, as it's a parallel arm that pushes with the button and goes onto the screen with a soft rubber pad, so it's not like a clothes pin style like some I've looked at before I bought this one. All in all a very worthy purchase and I'm going to use it often. The case is a little less than 4 inches square and maybe an inch and a quarter thick, so a coat pocket item that you can keep with you if you're on a short hike. As far as quality is concerned, even the document that comes with it is on heavy card stock. There's nothing cheap made about this filter or the mount. And of course, a threaded 67mm mount will fit any standard filter that you have. I have a kit full of 67mm filters, so I can go play with my phone with IR, Star, ND, graduated, and other things for when I want to go out somewhere and not drag along a 30 lb bag of DSLR gear.

For the price, this is an awesome polarizer for your iPhone! I do wish the clamp system sat more flush with the edge of the phone, and was more stable. But regardless it’s super easy to take on and off and move the filter.

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.

The K&F CONCEPT 67mm Press‑On CPL Phone Lens Filter Kit is a fantastic addition for mobile photographers who want better control over reflections and improved color saturation without bulky gear. Designed for iPhones with compatible 67mm threaded filters (including iPhone 12/13/14/15/16/17 — Standard, Pro, and Pro Max models with the right adapter), this CPL (circular polarizing) filter delivers genuinely noticeable results.
