This clip on ND filter is nice for the current price of $25.99. It is usable with your phone or regular camera lenses if they happen to be 52mm. The filter easily screws off of the clip for regular lenses. I found it a little tricky to use it with the case on for my iPhone 14 Pro Max. It takes some practice to get it just right. It’s made even harder if you’re working in bright light, which is one of the reasons why you’d want an ND filter in the first place. The glare on my screen made it very hard to see. That is not the fault of the filter, though, so I wouldn’t take away stars for that. The markings are very easy to see, which makes the filter easy to adjust to suit the situation. The clip has a rubbery piece that keeps it in place and keeps it from damaging your screen. I like the included case. I can keep this in my purse with no worries about the filter getting scratched. I took some photos with my phone for testing and will share them with no editing with and without the filter. I think The photos would be better with the case removed from my phone for a better fit. I also think I need to download an app that will let me adjust manually to use with this filter. I definitely recommend the filter. I think if you’re willing to take the time to figure out how best to use it with your situation it is worth getting.

Here's a quality lens that offers iPhone users a pro filtering option. This lens scores high for ease of use. Just twist the outside, and it quickly adjusts from max to min. I found it challenging to identify the optimal setting when shooting with my iPhone 13 because the bright sun made it difficult to see exactly what I would get in my finished product, so I ended up taking pictures at different settings to test them. It includes a protective case, which I find a bit bulky at 3.75" square by 1" deep, but still portable.

I've taken a lot of photos, but these best illustrate what the different settings on the lens can do and will help you assess whether you need one. In the boathouse sequence, low filtering helps bring out the background colors significantly, but with no filter, the blue colors offer the most appeal.

While I appreciate the lens's capabilities, I struggle with finding the perfect settings for my photos. This process requires patience and practice, and I'm hopeful that with more experience, I'll be able to harness its potential fully.

We also tested this briefly on an iPhone 15 and got different results. The iPhone 15 camera has an additional coating designed to reduce lens flare. We only shot a few photos, but the camera's processing seemed to kick in after opening the photo and adjusting them all to look roughly the same. I can't share what the processor is doing; the changes only become visible when the phone is in the "live" setting. (I turned off the live setting when I shot my photos.) My tests were inconclusive, but it's something that bears noting.

This fits fine on my iPhone 14. I like to be able to use this to help reduce sun flares in my pictures. Because this is tinted, it does darken the pictures.
This is easy to use, and it is excellent quality. It has a nice grip and holds well. It comes with a cleaning cloth and a storage case.

Quick and easy solution to reuse all my 52mm filter from my film photography days, the area that secure to the phone is made of rubber for secure holding to phone surfaces. The variable neutral density do have some artifacts when use in LED lighting environment.

This is decent, I never knew I needed it , it’s awesome how it filters out the light making the picture have a deeper intensity! Giving the photo a different perspective from the one without the lens. It reduces light without taking away from the colors. This is next level, and the price point was lower than what I expected. I love gadgets.

This is really cool, but I need to figure out how to turn off autofocus bc your phone will just try to adjust for the amount of darkness the filter is creating and it will just look like a normal photo

I rarely use the phone clip, though it is functional for that purpose and can make a significant difference when used appropriately. I do however frequently use this with adapters on every other camera I own that is threaded for filters! K&F hit it out of the park with this ultra-low budget friendly variable filter - I'm not used to using ND filters, but this has been a game changer for my [very amateurish] photography. My only complaint is that I wish the phone clip had a second joint and rotating pad, which would allow the clip to clamp squarely and more securely to my phones - some cases are very thick, and the design of the clip tends to sit awkwardly with my (admittedly chunky) OtterBox case. Clip aside, the filter is a 10/10 in my opinion.

High quality part in well protected packaging, used this with my cell phone right away and the results are outstanding.

This is a nice add-on for your phone's camera. Just clips on and covers your camera's lenses. I don't have any way to test the optical quality of the glass but it look fine to me and the build quality seems good. As an added bonus, the ND filter comes off the phone bracket and fits my Fuji X-T200's 52mm lenses. Nice addition to my camera bag and for when I'm shooting snaps with my phone. No information included so if you don't know what an ND filter does or how to use it effectively you can search the web. Recommended.

The “K&F Concept 52mm Clip-on ND2-400 Phone Camera Lens Filter Kit, Adjustable Neutral Density Filter” is a great ND filter to have for those very sunny days. We are taking a cruise to the Caribbean in June, and I got this for the trip. Have you ever looked at the pictures you took on a very sunny day? Some looked washed out like they were overexposed. A neutral density filter will give the shot more tone. This little device fits over your phone’s camera and filters the amount of light your camera lens sees. It is adjustable. I don’t anticipate using it much, but it is nice to have when you need it.
