K&F CONCEPT Clip-on Filter 52mm CPL Filters Polarizing for Phone Clip, Compatible with iPhone 17 16 15 14 13 12 11 Smart Phones(Not Compatible with iPhone 17 Pro/Pro Max)

I bought this to photograph my oil paintings. I always struggled to photograph them without the glare. However, this lens is amazing. It erased the glare even on dark colours.

Walked by coventry river on a half gray to white clouded day. The purpose was to test the lens when viewing water which glows from sunlight. Water can look fizzy and it did reduce it to be fair. It was a small reduction in glow but, enough to make the visuals more decent. Glow can be annoying on surfaces and can lose detail in visuals until it is tinted like cars, glass windows, rivers, limestone, tarmac.

very high quality strong grip great value comes in a nice quality plastic case and cleaning cloth you cant mess up using it its that easy and a card to scan to show how to use it takes amazing photos and durable i 100% recommend

Terrible, it doesn’t even work at the max nd level and when you increase the level an X appears and ruins the video. Its size is okay but I am having trouble firing it on my iPhone 17 pro. It is really irritating to install and is not worth the money I paid.

Average could be better but could be worse

Game changer for better quality pictures with your phone! Massive difference when used.

Filming videos through the windscreen of a car you usually end up with quite distracting reflections, especially driving along a tree lined road with sun flicker. This lens filter removed 90% of windscreen reflections and in parts of my footage it looks like there is no windscreen at all! Now, I've read the one star reviews saying it doesn't work, but that's because the user doesn't know how polarising filters work. They have to be rotated to give the desired polarisation. If rotated to the "wrong" position the glare increases, but if rotated to the right position, the glare all but disappears - and that's why the lens is rotatable! But the effect is difficult to see with today's monitor screens, even on a large screen cellphone. So it requires some sacrificial shots that you can view on a large monitor. In my application with the clip upright, the lens was rotated such that the two grooves were horizontal, and that cancelled out 90 percent of reflections. Perhaps try that before misleading would-be purchasers with one star "do not buy" reviews, which are very misleading and annoying.

Nice compact filter that actually cuts reflections and deepens colors when shooting on my phone. The clip feels sturdy and it fits over my case without issues. Only thing is you need to adjust the angle a bit to get the best effect, and it can shift if you bump it. Not perfect, but for the price it’s a solid tool to step up mobile photography.

Produit conforme qui fait bien son travail. Le filtre fonctionne parfaitement. Rien à redire.

Très bien si vous faite du carspotting la calité est vraiment bien et pour les moto

Very happy with this item as it has a 52mm thread so you can use filters with the same size.

This is a great filter, which helps with some of the iPhone's lens reflections. In the past I've recorded video on trips and there are reflecting dots moving around in the image. It's my understanding this happens because the iPhone lenses are so shallow and it's unavoidable. This filter helps with that. The case is nice and light, allowing you to easily get the filter and it's clip out easily and quickly to use on your iPhone. For the price, it really can't be beat and such a simple improvement for your photos. You can rotate the lens to decrease or increase the amount of light your camera is sensing, so everything isn't overexposed. Wish I had this years ago. Recommending to friends who really enjoy taking photos.

It's a must have! I have been using this K&F Concept ND2-400 Filter for the last two years, and it has completely transformed the way I film with my smartphone. If you frequently shoot outdoors, this filter is an absolute game-changer for your image quality. Key highlights from my experience: Precision Control: The variable range (ND2-400) allows you to reduce exposure by 1 to 9 f-stops. This is crucial for maintaining the "180-degree shutter rule" in video, giving you that smooth, professional motion blur even in bright sunlight. Versatility: While the clip-on system is perfect for smartphones, I love that this is a standard 52mm filter. You can easily attach it to any DSLR or mirrorless lens with a 52mm thread, making it a very cost-effective tool for any creator. Image Quality: It significantly improves the dynamic range you can capture on a phone, especially for landscape photography and long-exposure shots. Durability: After two years of regular use, the mechanism remains smooth and the glass quality is still top-notch. Final Verdict: If you are just starting to create content with your smartphone and want to take your videos to the next level, this variable ND filter is a must-have. It’s easy to use, versatile, and built to last. Highly recommended!
