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.

The filter set is supplied in a storage box with a foam insert. This is still in a box printed with the most important information, which is shrink-wrapped again for protection. On the 2nd picture you can also see the different tint levels of the individual lenses. In the video you can see that the CPL lens can be rotated without detent to adjust. On the last picture you can see that K&F has oriented itself to GoPro in terms of attachment and also relies on the proven bayonet lock via wire bracket. However, the housing of the individual lenses is not made of plastic, but of aluminum and, as can be seen in the 4th picture, even has cut-outs to make handling easier. The lenses are all printed for quick selection. Here, however, the alignment of the print triggers me. You can see on the 4th picture that the prints do not point in the same direction on the lens. All in all a very well made and valuable lens set for the GoPro.

The GoPro is an excellent, versatile and almost indestructible camera. The robust market for third-party accessories makes it even better. You can already get every type of mount imaginable, but in recent years there has been an influx of filters and other lens modification accessories. This is particularly useful as it reduces reflections and glare that can obscure what you're actually trying to photograph. This is especially important for the GoPro, since you'll often use it on snow or water — both surfaces are prone to reflections. The four different filters offer light reduction options for all weather conditions (e.g.: ND8 for cloudy days, ND32 for sunny days) and are perfectly matched to the GoPro lens housing. If you use your GoPro outdoors at all - and I imagine most people do - these filters are essential. We recommend!

Filters for Gopro Hero9 really good and quality. Very nice also aesthetically with a metal frame that perfectly matches the Hero9's lens. Because these filters mount, replace the original Gopro lens cap and don't put them on it. They are easy to use and apply, packaging is minimal with a very handy transparent plastic case containing filters and a cloth for cleaning. Really a good product

Makes the GoPro footage look much more solid and the colors are more lifelike. I bought a lens cap at the same time and have been using it for a few weeks with no scratches or peeling of the film on the lens. For me it has completely replaced the original Gopro lens

The item came in its rigid and reusable packaging to put on the original GoPro lens. Excellent adjustability using the ring to find the optimal polarization. Absolutely recommended brand

They are easy to install on the GoPro, their build quality is excellent. Even the lens immediately shows an improvement in photos and recordings. Advertised with flying colors for the time being.

The filter works excellently, as I know it from my SLR camera. Since I don't have a GoPro camera, I had to make an adapter ring to attach the filter to my action camera.
