It works fine. I like the ease of use the most! Just wish I had gotten one with more stops of ND is this range doesn’t cover all the situations I need. But the product itself is fine!

This work so great, it's a lifesaver with your iPhone in the outdoors. High quality and a great value to add to your iPhone gear kit.

I really like this filter. It has adjustable density — you can change the value simply by rotating it. It’s very helpful when shooting on a sunny day.It fits the iPhone 16 Pro perfectly. The magnetic mount holds well if you remove the silicone case and attach it directly to the phone body.It also comes with a nice, convenient protective case.

Very stable, the magnet is strong enough to fit well on the iPhone.

Great article. For compatibility with a 16 pro you have to take the 6.1" and not the 6.7"

Basically it’s okay. If i be super detailed, the size of the metal back with magnet is not exactly like mentioned 6.1 inch. It’s little bigger.The other downside i found out later is that vnd filter doesn’t have cap, so you’re expected to remove it all the time after each shoot and keep in the pouch

Great quality phone filter that easily fits on my iPhone 16 Pro with MagSafe. It’s easy to use out of the box and fits my iPhone with a cover. Image quality is great and slows down my footage so that I can shoot at very low ISOs in bright sunshine.

I have now used the magnetic holder with ND filter several times and am overall very satisfied. Positive: - The fit is excellent; the holder sits securely on the iPhone and does not slip. - The quality of the filter makes a very good impression. I didn't notice any degradation in image quality, even though I'm not a professional analyzing every detail. - The ND filter can be adjusted continuously so that you can adjust the desired darkening very flexibly. - In combination with an app that allows manual exposure, I was able to take impressive long exposures in daylight, for example to beautifully blur running water. - Very practical: The holder and filter come in a sturdy bag that provides protection when you're on the go. Negative: - Unfortunately, the bag smells extremely strong of chemicals. Even after prolonged ventilation, the smell has barely improved. - To use the holder, the iPhone case must be removed. Not a problem for me personally, but could be annoying for others. Overall, a well-thought-out and high-quality set that opens up great creative options for iPhone photography. Apart from the strong smell of the bag (which will hopefully disappear at some point), I am absolutely satisfied and can recommend it.

The MagSafe mount makes a very high-quality impression and is really practical to use. The attachment holds reliably, the supplied ND filter is cleanly finished and can be used quickly and easily. The system is a great solution, especially for spontaneous photo and video recordings on the go. The only downside: The cutout is unfortunately not compatible with mobile phone cases that have increased camera protection. As a result, you either have to work without a case or use a very simple case. A bit impractical for me, but no reason to devalue the product overall. All in all, a well-thought-out solution that serves its purpose excellently — with a slight limitation in case compatibility. That's why “only” four stars.

As an amateur photographer, I'm thrilled: I can finally use a variable ND filter on the iPhone, as I already know it from my SLR cameras. Although the shutter speed on the iPhone cannot be set manually as precisely as with a DSLR, the ND filter visibly extends the exposure — making the photos look more natural and often even more detailed than without a filter. I find it particularly brilliant that the filter has a classic 67mm thread. This means that it not only fits the iPhone via the magnetic holder, but also to my DSLR lenses. This allows me to use existing filters for both systems — a real link between smartphone and DSLR photography. The MagSafe mount securely holds the filter to my case. Despite the edge of the case, there are no problems with shading in the image. This allows me to install and remove the filter quickly without despairing of fumbling. As I already know it from the camera sector from K&F Concept: Although a Chinese manufacturer, they deliver very good workmanship that is in no way inferior to established brands — and at a fair price. Positive: • Variable ND2—32 filter for flexible exposure control • 67mm thread — can also be used with DSLR lenses • Sturdy MagSafe mount, no wobbling or slipping • Clean workmanship, good image quality • Impressive price/performance ratio Negative: • iPhone exposure control limited, effect not always usable to the maximum (but is due to Apple and not to the filter!) Conclusion: A top tool for photographers who want to combine smartphone and DSLR photography. It's fun, visibly enhances images and brings flexibility to the setup.
