got a cage for my new GoPro 12 that allows for traditional 52mm camera filters. Usually you have to get the funky square filters for the action cameras, so it's pretty cool to be able to use filters I already own. But I didn't have a good UV filter that wasn't already used on my regular camera lenses, so I got this filter and it works well, and I appreciate the inclusion of a lens cap. The only negative thing about this filter when used on a GoPro cage is that I get a little vignetting when using the camera on the widest setting, "Hyperview." I rarely use Hyperview, so no big deal, but it's worth noting that this thin filter may not be thin enough if you're using it on a super wide angle lens. Other than my minor issue, which probably only occurs when used with a GoPro, I can't find any other faults. If nothing else, I've added another layer of security to my expensive action cam.

am very satisfied with the quality of these filters! They rotate on and off my GoPro HERO10 Black lens very smoothly and securely. They are very comparable to the regular models my camera came with — same dimensions, weight, and clarity. I've spent most of my time using the polarizing filter from the set so far and it works great! I'm still a beginner but I can really see a difference in surface reflections in my photos. One thing to note is that I can't wear my GoPro's protective silicone case while using this particular filter, as the case extends to the edge of the case, covering access to the dial that you rotate to set the polarization. The four filters are supplied in a plastic case firmly fixed in foam. I found this very reliable and protective when taking them with me on trips because I could keep them in my backpack with no worries. All around very satisfied!

The black piece you see in the photo is a lens cap. The transparent piece that is underneath serves as a kind of filter. The cap underneath is more of a free-pass attachment that sticks to either the filter or the lens cap, depending on what your goal is.

It's basically just magnets, so it was really easy to set this up. I just screwed in the base, then the filter clicked into place with no problem, then the lens cap snapped on with no problem.

The quality of this set is great. Appearance is great too. I shook the camera a little and the cap didn't fall off. Seems to be a great alternative to the locking mechanism that comes with regular caps.

Overall I am very satisfied with this set.

Although I'm a great fog filter, I can sometimes see the black dots in my photos even though the lens, glass and sensor are cleaned so I know it's the filter itself. It often messes up my camera's autofocus when trying to focus on the dots on the filter. When everything works right it's a great filter and makes for some cool looking diffused photos.

Excellent quality and works great with GoPro 10 Black.

The black piece you see in the photo is a lens cap. The transparent piece, that is under that, serves as a filter of sorts. The cap under that is more of a free pass through attachment designed to stick to either the filter or the lens cap depending on what your goal is.

Basically it's all magnets, so it was really easy to set this up. I just screwed in the base, then the filter snapped on no problem, then the lens cap too snapped on without any issue.

The quality of this set is great. The look of it is awesome too. I shook my camera a bit and the cap did not fall off. Seems to be a great alternative to the locking mechanism that comes with normal caps.

Overall, I'm really happy with this set.

This K&F Black Diffusion Filter is an excellent kit. It reduces the contrast, makes the black tones a little grayer and ensures a gentle bloom around the highlights. There are four filter strengths available; from weakest to strongest, they are 1/8, 1/4, 1/2, and 1. This 1/8 filter is the weakest, but it still makes a noticeable difference to the look of the pictures you take with it.

While a great misty filter, I can sometimes see the black dots in my photos even though the lens, glass, and sensor are cleaned so I know it’s the filter itself. It often messes up my camera’s autofocus as it tries to focus on the spots on the filter. When it all works properly it’s a great filter and makes for some cool looking diffused photos.
