So I took these photos with my iPhone 13 Pro Max. The first photo is with no filter and then progresses from ND2 to ND32. I did not further alter these photos in anyway, it is just what my camera automatically adjusts to. I do think the colors and details are a bit more vibrant in the photos with the filters.

What I also love about this set of filters is that the design works with a case. I have a case on my phone and I did not have to take my case off to use this. The magnetic design is also great if you want to be able to take off or put on the filter really fast. I've seen some designs where you have a separate filter for each ND, this is just all in one.

Very good filter system with the most common filters you need. I use this on an iPhone 15 Pro Max using a filter holder for taking pictures and filming. Thanks to the excellent magnetic adhesion, the filters sit firmly on the holder, but are still easy to change in seconds. The image quality is not negatively affected by the filters and is fantastic overall. The price-performance ratio, especially in the set, is great.

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.

was happy to find this filter set for the GoPro 11 with its 3 different ND filters and a circular polarizer that actually rotates to get the best effect. It really isn't CPL in my book without the rotation feature, so I was glad this tiny CPL filter had that capability and was easy to adjust. I have a “mini” version but the filters fit both the mini and standard sized GoPro 11. The fit is identical to the original GoPro filter that comes pre-installed on the camera. Admittedly, I had to look for a way to remove the filter as I didn't want to break my new camera, but it turns out it's a simple twist of the filter 90 degrees to remove it. It requires a little strength, but that's better than being loose. The filters go back the same way, just pay attention to the two metal rods. It's obvious how to line them up once you see the clamp holding them. A set of ND filters can really open up some creative options, e.g. B. longer exposure times. A polarizing filter is a great way to remove reflections off water and glass, and to darken the sky for better color saturation. The construction of the filters themselves appears to be premium and feels premium. This filter set comes in a simple but very nice case that keeps all four filters safe. The box is about the same size as a regular single filter housing and doesn't take up much extra room in the camera bag. So where the GoPro is going, this filter set will go.

I have a cage for my iPhone 15 Pro Max and 14 Pro so am able to fit screw on filters but my lowly but much loved SE has no such luxury.
This meets that need with the added bonus that I also have a whole bunch of lenses that take a 52mm thread filter too

tested the ND/PL kit. The filters are delivered protected in a storage box. The attachment is very easy thanks to the bayonet lock. The filters fit perfectly and firmly on the camera - I use the GoPro Hero 11. The processing of the filters is impeccable and the price is therefore justified. I've been pretty happy with my no-filter shots so far, but these filters really add value to the shots. Thanks to the 4 filter strengths, you always have the right one for every exposure situation. The polarization is a perfect help with glare and reflections - I already knew that from my polarized sunglasses. With the use of filters, special effects are also possible - eg intentional blurred motion due to longer exposures, which would always lead to overexposure without filters. Conclusion: If you want to exploit the possibilities of your Hero 9/10/11 even more, this filter set is of very good quality, so I give it 5 stars and a purchase recommendation.

This filter is very made of aluminum, slim and very light. Very well constructed.
Because this filter is 52mm , but designed to fit a 50mm size lens, you will not be able to :
1. attach your lens cap (maybe a 52mm lens cap would fit)
2. attach your lens hood
3. attach any other filters to this one. You are able to attach 50mm filters to your lens, and then stack THIS one onto those filters. I did this with my CPL filter, but found it difficult because I had to rotate the CPL , and then rotate the Variable ND filter, so I removed the CPL for now.
Also, I need to investigate whether it is even advisable to use a CPL and ND together because of the low-light.

It is really a nice feature of this filter to incorporate 1 to 11 stops on this one variable filter. It makes it easy to dial to the stop that you want to use, but I found it a little confusing. The stops are labeled with Min on one end, Max on the other , and 8 dots in between.
So I'm not really sure what dot corresponds to what ND stop, there are supposed to be 11 stops, but there are only 10 markings.
Also , there is no lock at the beginning or end of the 10 stop markings.

Anyway , I've been experimenting and getting to learn how to use it.
I see how it it very convenient to have only ONE Variable filter, instead of several. Much less exptensive, much less complicated. But it is going to take me a little bit of time to learn how to use it efficiently.

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.
