This is a very solidly constructed filter kit! There is a clip-on bracket adapter which has a thumb screw to tighten it down until it snugly fits onto the iPhone camera lenses. It is designed for pro iPhones with three camera lenses. It fits perfectly on both my iPhone 14 Pro and 15 Pro Max. It is magnetic so the polarizer lens snaps right onto the bracket and can be removed quickly as to not interrupt shooting different scenes. I like that there is also a cold shoe if you have other accessories to attach. Plus its magnetic bracket can also be used with other 67 MM filters which is really a plus! There is a soft cleaning cloth and zippered soft case included.

The only issue I have with this set-up is the potential to crack the iPhone screen if care isn’t taken to not over-tighten the screw. The other issue I see is how advanced these new iPhones are and how easy it is to correct exposure and highlights in the phone and the necessity for a CPL filter isn’t what it used to be. I took a ton of test images but the only two which showed the difference were the shots taken of bright clouds on a sunny day using the iPhone automatic settings. In that situation, yes, this works well and I would say if you are an outdoor scenic photographer using an iPhone, this would be a nice filter kit to have and a time saver as you could keep shooting without having to manually adjust exposure. I will definitely use it for sunset beach shots when I get the chance. I think for the price it is a good value.

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.

The binoculars are equipped with high-quality lenses that provide images with good clarity and detail. These binoculars are a good choice for hiking!

I needed a good hood for my IPhone.... I use external lenses and filters on some of my shots and they are threaded to 52mm... I use a step up from 52 to 58 so I can match the filter and lens size on my DSLR... One size lenses now for both... The hood helps cut down light anomalies and flare that I am not looking for in the pictures...

Great camera and Bluetooth system

I like to take photos with my dSLR camera. Unfortunately, sometimes I don't have it with me and I take photos with my smartphone. To be able to be a little more creative, I tried this ND filter on my iPhone 15 Pro max. The filter holder holds various filters with a size of 52mm. When the iPhone is used without a case, the holder completely encloses the cosmic lenses. Although the holder is of course visible from the front, Face ID unlocking is not affected, which I find very positive. The setting options on the ND filter itself are seamless within the specified range. This allows you to take creative photos. Of course, other filters with a size of 52mm can also be used. It would also make sense for me to use CPL and star filters as well as close-up lenses. The fact that I can now use other filters alone improves the iPhone camera a lot and I'm sure I'll be able to take nice photos in between without having to lug the "big" camera around with me all the time. By the way, I already know the company K&F Concept from various filters for my dSLR lenses and have always been satisfied and convinced by them. In any case, for anyone who wants to get more out of their iPhone shots and the unlimited possibilities for using various other filters make the product a must! for photographers who want to create something more than standard images.

I own two old manual only ZOOM NIKKOR lenses adapted to Fuji X, one 80-200/4 and the other 100-300/5.6. Use them for video. K & F are on the cheaper side of the filter market, so they are totally suitable for my purposes and fit the old lenses well. This is a cost effective solution. No complaints about the image quality, although the threaded ring was perhaps more robust and a little better machined, but it is still good enough.

I love this camera. It takes way better pictures than my phone, especially at night with the flash or if I need to zoom in. Plus, it’s super easy to transfer the pictures to my phone.
