Love these 3 magnetic filters, and the included magnetic ring with "threads" so I can use magnetic filters on my more conventional cameras. I use them on my iPhone 13 ProMax "Small Rig" (which is also amazing).The ONLY reason I'm giving these fantastic filters 4 stars instead of 5 is that the set that they sent me has a UV filter "with threads" and it just doesn't work with the magnetic mount. Other than that, however, these are perfect, and it is simply brilliant that you can change filters in under 2 seconds.Not such a big deal though, I have other 52mm lenses I can use the threaded UV on. But still... wish the order would have had the threadless UV.

You get what you pay for

trabajan super bien en mi lente , me enamore de ellos

This concept is revolutionary! The filters are of very good quality, solid, delivered with a very good quality pouch as well. Very easy to use, the ring is screwed onto the lens in 2 seconds and then the filters are magnetized. I have been able to test lots of times and never has a filter come loose! Additionally in this kit there are the 3 main filters and essential to have. I recommend

The filters work well individually, with no noticeable colour cast on the ND filter and only a slight warming of the image with the CPL. The magnets appear to be strong enough, the CPL rotates smoothly and I wouldn't worry about them falling off.A minor issue is that the pouch hasn't been stitched properly, so it's a little bit deformed on one side. But it's still perfectly usable, and is small enough to fit comfortably in my camera bag.Overall I'm happy with the performance of the filters, but I don't seem to be able to stack the CPL and the ND without a diagonal darkening of the image. This depends on the rotation of the CPL, and it's either from top-left to bottom-right, or top-right to bottom-left. Disappointing, but it's probably rare that I'm stacking the filters.

I had a great time with these magnetic filters, purchased with the 82mm diameter as it is the largest thread among my lenses, so that I can also adapt them with the appropriate adapters to other lenses with a smaller thread, excellent quality, I recommend them

Good kit, but the filters introduce a warm cast that needs to be corrected in post-production... it can be done but it's a bit boring to have to do it for each photo. Another thing: the lens cap (in my case a Nikkor Z 24-120 f/4) does not attach well when the filters (or even just the adapter) are mounted. The risk of losing it is very high. There was definitely room to have that extra mm to allow the cap to attach well.

Used on rf 24 to 105 and 100 to 400 lenses

Excellent quality material.

As a photographer, I use filters, but it's not always easy to put on or remove depending on the situation. But with this system, it becomes so simple that it is almost instantaneous.
The product is of very good construction quality and comes with a 4 pockets pouch very well made and resistant against possible blows. It can be attached to the belt thanks to a scratch. The kit consists of two screw rings, one UV and a vacuum on which you can attach the CPL filter or the ND1000.
I wanted to go and test this new product. First with the CPL filter alone and then with the CPL+ filter the ND1000 together. The results are just staggering. Here are the rendered with the CPL filter on the left and the CPL+ ND 1000 on the right. With the filters, there is no loss of dipping, and the color drift is almost zero. The CPL filter polarizes perfectly and the ND 1000 filter is very amazing by its performance, it is very thin which limits vignetting, a plus. Using both together, it is better to avoid the ultra-wide angle focal lengths, but from 16mm, no worries, we can add them up. In addition, they are compatible with my sun visor, I was able to put on and remove them without having to remove it very easily because the magnetic force is perfectly dosed.
Really very satisfied with this first release, I hope that other magnetic filters intermediate with this system will come out soon to complete the offer.
If there were magnetic lens caps, it would be great.
This is a very good investment and the price is more than correct given the quality and results obtained.
