The smartphone lens filter from the K&F Concept brand impresses with its excellent workmanship and quality. The variable ND filter, which is easily and securely clipped onto the iPhone lens using a clip, is particularly impressive. This innovative approach makes it possible to use the advantages of a professional ND filter on the iPhone as well.

The filter is extremely easy and intuitive to use. The clip holds the filter firmly in place without slipping, which enables uncomplicated and quick installation. This is particularly practical when you are on the move and need to react quickly to changing lighting conditions.

Another plus point is the photo quality, which is not affected by using the filter. The images remain clear and sharp and the effects of the variable ND filter are well presented without color distortions or other unwanted artifacts. This makes the filter ideal for anyone who wants to take high-quality photos with their smartphone.

Overall, the filter offers an excellent way to improve the flexibility and quality of smartphone photography. It is easy to use, well made and ensures that the photo quality always remains at a high level. A clear recommendation for all smartphone photographers who want to expand their creative possibilities.

I use the ND filter with my iPad.
Since I already have a few things from K&F, my expectations regarding quality were correspondingly high.
I was not disappointed.

Overall, a great filter.
5 full stars.

The K&F Concept universal cell phone camera lens set is perfect. I'm often by streams and especially around midday the shots are always a bit bright.... I've often heard that you can get a lot more out of an ND filter. The clamp holds the filter securely over my P40 Pro, even with a thin case. The filter can be easily adjusted with the clamp. Since you can adjust the filter, you should take the time to experiment a bit. It's worth it! I was able to create much better saturation. It comes in a sturdy, sealable plastic case and can be stored in my gimbal bag. I'm very satisfied. For me as a YouTuber, it's an inexpensive, simple improvement in video quality. Happy to give it 5 stars.

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.

Here you can get a cell phone camera lens filter with a 52 mm thread from K&F Concept Universal. It is a variable ND filter with a strength of ND2 to ND400. The desired strength can be set by turning the filter. It is supplied together with a corresponding lens clip, a cleaning cloth and an instruction manual.

The clip is simply attached over the camera and the ND filter can then be screwed on. Contrary to the description that it is only suitable for the iPhone, I can say that it can also be used for other cell phone models and fits well there too.

It is suitable for extending the exposure time. If you have a camera with a suitable lens (i.e. 52 mm), the filter can even be used here.

Give a unique and clear view.

This is a great lens filter for use with the smart phone
It has a nice effect on the photos and would recommend giving it a go and play with the settings available on the phone as well to get a great result
The clip itself is a little large for being portable but it does hold it in place well so it does the job.

Arrived in a somewhat branded box, inside is the lens itself that comes in a small travel case.

I'm using this on an iPhone 11 with a case and It was pretty awkward to use as it didn't sit flush with my camera, resulting in some alternative-looking photos, not only that, but the attachment takes up a huge chunk of my screen, so this is better suited for larger phones.

The lens does work and you can easily control how much light input there is using the dial on the lens itself, which is conveniently marked out.

It is very easy to set up and operate, and if used correctly can take some very good photos, id say this is an excellent entry to photography and video work, as you're not forking out over an expensive camera and wondering how to operate it.

The cleaning bag is a nice must-have that was included. The lens also has beautiful filters. I've had good experiences with it now; I was able to adjust the lighting conditions so that the video and the image were clear. I'm very satisfied and find it extremely comfortable. There's a clipper on it that can be perfectly mounted on the iPhone lens.

I recently tried out the 52mm Clip-on ND2-400 Phone Camera Lens Filter by K&F Concept, and it's transformed my phone photography experience. This versatile filter offers a wide range of light reduction options from ND2 to ND400, allowing for creative control over exposure in various lighting conditions.

The clip-on design makes it compatible with a range of smartphones, including the latest iPhone models, ensuring that I can achieve professional-quality results with my mobile photography. Whether I'm capturing landscapes, portraits, or action shots, this filter helps me achieve the perfect balance of light and shadow.

Overall, I highly recommend the 52mm Clip-on ND2-400 Phone Camera Lens Filter to any smartphone photographer looking to elevate their images. It's a compact and convenient accessory that delivers impressive results, making it a must-have for mobile photography enthusiasts.
