This ND filter was developed specifically for the iPhone. This should be taken into account, otherwise the verdict will probably not be so favorable. The special thing about it is that this ND filter with its filter ring completely encloses the camera module of the newer iPhones. The actual filter then lies directly on the lenses and sits really well.

Unfortunately, this doesn't work with a cell phone case that has a camera protector. Then the camera module becomes too big and the filter no longer fits over it.

The whole thing is held in place with a fairly tight clamp, which of course then covers part of the display. But in my opinion that's not particularly important.

The filter can be adjusted from filter strength ND2 to ND400 by simply turning it. The whole thing is done with a quarter turn, so all levels are pretty close together, so you should turn slowly. There is a 10-level division on the ring, but it can still be adjusted continuously. The filter does not always have the same effect on all three lenses. With the ultra-wide angle of the iPhone 14pro, for example, you can get the filter ring in the picture with some settings. In some settings you notice a slightly stronger vignetting. You have to try it out a bit, but you can get the hang of it quickly.

Who needs something like that? Certainly no one who doesn't know straight away what an ND filter does. The product is aimed more at photographers who want to get even more out of the iPhone and, especially in bright light, still want to use long shutter speeds. To do this, you would have to delve a little deeper into the subject. There are numerous, very good YouTube videos on the subject...

I think it's really great that the filter holder or clamp with a 52mm thread can also accommodate other filters. A polarizing filter or graduated filter would be exciting here for different effects.

In any case, I am very happy with this ND filter, even if I probably won't use it that often. I tend to take the photos or videos that can be produced with it with a system camera. But if you're travelling light or want to experiment with iPhone photography, this is the right choice. The price is unbeatable for this great quality.

This is the best ND solution I have found. I am using an iPhone 11. The filter attaches easily and the clip is firm. The filter is so easy to adjust and I cannot fault its operation.

I use the iPhone 11 which already gives average-quality pictures because of an old phone. but this lens makes the picture a little better.

The main thing I liked about this lens is, that I could easily adjust the light making the pictures better.

it is easy to attach to the phone.

Since it is a clip, it does cover the screen bit which sometimes seems annoying when taking group photos.

It definitely improves screen quality. And I would definitely recommend it.

I bought the K&F Concept Universal Cell Phone Camera Lens Set with Filters for my iPhone and I'm very happy with it. The set includes a 52mm variable ND2-ND400 filter that allows me to easily adjust the exposure and shutter speed of my cell phone photos. The quality of the images improves significantly, especially in bright light conditions or when shooting moving subjects. The filters are easy to install and fit perfectly on my iPhone. Overall, I'm very happy with this lens set and can recommend it to anyone who wants to improve their phone's camera.

I have my iPhone in a protective case and the clamp is large - so easily grips phone without need to take out of otter box case. I have been photographer for years and have handled lots of equipment - and this is very well designed and constructed. After I order I was worried maybe I tried to buy cheap product - but now that I use it - I am so happy with quality and low price! The bluetooth set up was super easy. Battery was already installed and it took about 30 seconds to read instructions and sync shutter button.

I have been looking for a CL/ND combo 52mm filter for my iPhone 11. This one is excellent and the right one to use on overcast days, or in bright interiors when I need to keep the shutter down to 1/48 and don't want high lights to blow out.

I put this outside in the sun to test it ... I took my iphone 11, the battery was dead, and in 45 min was fully charged.... i have taken it camping with many time and works awesome when BOB (Big Orange Ball) is out.
Lightwieght ...nope your not going to go backpacking with this item thats for sure. but it works awesome. I can easily recommend this product

This camera is better than my iPhone 11 and gives my face a more structured look. It picks up on colors and textures better which is a bonus. I wouldn't buy this if you want a super super high-quality camera but its flash gives a nice Y2K vibe which is great for Instagram photos and selfies with friends. Overall I'd say it's what I wanted even though I'm not sure it's worth the price.
