K&F CONCEPT 58mm 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, 58mm Threaded Filters

K&F Concept nailed it with this clip-on iPhone filter! The build quality feels excellent—solid, precise, and pro-level. It clips on securely and doesn’t shift around, and once it’s on the image quality upgrades instantly. Colors are richer, glare is reduced, and it gives that cinematic edge I love for mobile shooting. If you’re shooting serious content with your phone, this is one of those small accessories that makes a big difference. Comes in a great hard-shell case and lanyard too.

I tested the K&F Concept 58mm kit to eliminate obnoxious reflections when shooting with the iPhone 15 Pro Max. This polarizing filter (CPL) works by filtering light reflected from shiny surfaces such as glass, mirrors and bodies of water, making shots sharper with saturated colors and increasing contrast. The magnetic pressure clip is attached with a simple push: just insert the lens into the holder and that's it, without complicated mechanisms or fragile attachments. Feather weight of 19.3 grams, almost like a coin. The inner silicone ring adheres perfectly to the back of the phone, preventing slipping when rotating the filter to find the best angle. The zip case and red cord keep everything organized in the bag without cluttering up. In 30 days of intense use I have photographed landscapes, outdoor portraits and shop windows: the filter really eliminates the annoying reflections that ruin the composition and amplifies the details of the sky and water. The optical glass keeps the shadows intact without bleaching the image. Only consideration: the mount is universal at 58mm, so check compatibility before buying. The case and the lanyard are also nice and comfortable.

K&F Concept 58 mm filter kit with CPL filter. I was interested because he shot professional footage with high-end mobile phones and different accessories. In my case, I make the recordings outdoors and what this filter gives me is the minimization of glare, of reflections. It doesn't eliminate all of them, but it does minimize glass, water and metal. In addition, another side effect it has is that the saturation increases a little, as does the depth of color. It gives a slightly more professional profile, but it's not that it's excessively noticeable either. This is an accessory for people who want to take great care of the image and, well, if you are going to work with landscapes, photos in a river, reflections with glass, it is very useful. However, it can subtract a little bit of light from the lens, so be careful to use it indoors with low light. Regarding the packaging, I really liked the presentation, the case in which we have the filter and I also really liked the fastening system on the mobile phone. These types of accessories are what make the use of these filters democratic, not only on iPhones, but also on other high-end Android phones that do not have specific accessories for them. On the other hand, K&F is recognized worldwide for the quality of its lenses. It doesn't have an exaggerated price, so if you are an image lover and you want to pamper the image a little more, (although this product is nuanced, it doesn't change the product crazy), it simply reduces brightness, increases the saturation a little and gives a little more depth of color. For my part, recommended.

There wasGood evening, the product is of quality and I can say and guarantee that it is a product that goes beyond expectations, it works great even with smartphones not indicated, but I guarantee compatibility with the Xiaomi Redmi Note 12 pro 5g (in my possession), so I assume it is compatible with many other smartphones. Recommended product.
a dent in the outer box, and the case was also damaged, so I returned it. I was looking forward to it, but it's a shame. Can I return it, but can't I exchange it? I would like to exchange it because of the trouble of buying it again. Additional 1/20 When I contacted the manufacturer, I was relieved that they could handle it. I will post another review of the product itself at a later date.

---CONCLUSION---
I am really impressed by this 58mm filter clip with CPL filter for mobile phones. The workmanship is very good, the materials are of high quality and the clip is securely attached to the mobile phone. The clip is quick and easy to attach and stays securely in place even when moving. And the filter is also easy to attach to the clip by screwing it on.

Due to the large diameter of the filter, all three cameras on my S24 Ultra fit easily. The filter can be used very flexibly, as it can also be mounted on compatible 58mm lenses from real cameras. Speaking of flexibility, the filter can also be rotated, which allows you to adjust the filter strength.

Initial test shots of reflective surfaces have already revealed differences, but the full potential will only be revealed in summer.

For anyone who uses their smartphone to take pictures or film, this filter clip is a clear recommendation. It increases quality and helps to achieve artistic effects. Full five stars C37

The thread of both the filter and adapter is good and they can be easily screwed together. I use a Samsung Galaxy S24 and the adapter fits easily on the phone with the case. I did a small test on a 1:18 model car right after unpacking, which I have included here and the result is clearly visible. I will take more pictures when the weather conditions are better, but as of now: Recommended

I'm an iPhone 16pro user. The case is quite hard and thick so that it can be used normally, but this filter mount can be sandwiched with plenty of room. I still don't know the performance of the filters that come with the set, but I think I can say that this mount alone is worth 5 stars.

Picked up this K&F Concept clip lens as a fun add-on for me and my photo-happy teenager. Out of the box you get a tidy little case with a lanyard, and while the zipper was stiff at first, it loosened right up. It's listed as compatible with iPhone 17, but I clipped it straight onto my iPhone 13 without drama and was shooting in seconds.Pros: The clamp mount is solid and non-sticky, so no weird adhesive on your phone. It visibly changes the image--slightly darker and more diffuse--so you can see a real "before/after" when you pop it on and off. Big bonus: it uses a 58mm thread (Nano K-series 58mm), which means you can experiment with other 58mm lenses if you've got them. Setup is simple--just thread carefully and you're good.Cons: The packaging doesn't clearly say what specific type of lens is included, which is a head-scratcher. You'll want to clean the glass before shooting, and the threading needs a gentle hand. Also, the effect isn't some mind-blowing transformation--think subtle mood shift rather than a whole new camera.Bottom line: A neat, affordable way to experiment with mobile photography. Great for tinkerers and casual shooters who enjoy playing with looks; not for someone expecting a dramatic optical overhaul.

Got this for my photographer boyfriend who shoots a lot of automotive iPhone content, he loves it!!

The universal CPL filter clip basically fulfills what it promises. The polarization effect is clearly visible: reflections on glass and water are noticeably reduced, colors appear richer and contrast improves — especially when shooting outdoors in daylight.
The clip is easy to attach to a smartphone and fits securely in most cases. The workmanship makes a solid impression and the filter itself has a high-quality coating.
There is a star trigger for handling: Depending on the smartphone model and camera position, it takes a bit of sensitivity until the filter is really optimally aligned. In addition, the clip can be a bit fiddly with very thin or very thick device cases.
Conclusion:
A useful CPL filter for smartphone photography with good image effect. Not a professional accessory, but for the price, it's a good solution for better photos on the go.
