Great filter.

I've owned and used other K&F camera products and this 4-Pack Lens Filter is another quality product from them. The glass and the filter frame construction is lightweight and quality made. The item(s) that interested me the most was the CPL as well as the ND8.

The 2 particular filters help when I'm shooting in and/or into the sun. It's something I was wanting to get for a while and glad it came from K&F.

Great items.

Fits like factory and the filter feels very high quality! It gives amazing motion blur and is perfect for giving my drone shots a more cinematic feel. Would buy again!

K&F have been making filters for a long time and have a good reputation. These filters are no exception. They fit on my GoPro 10 without a problem and the quality appears good. The photographs included show the carrying case and filter selection as well as a comparison between the original GoPro filter and one of the K&F filters. The polarizing filter is likely the one I will be using primarily and the picture quality is excellent. They have included white reference tabs on the filter which helps in setting up and comparing shots.

Bottom line: Great filters, good quality, nice carrying case included!

TL;DR- Mostly use the CPL filter and it's fantastic. Fits my GoPro 9 perfectly and the storage case is actually quite good.

I'm very happy with the quality of these filters! They twist on and off of my GoPro HERO10 Black lens very smoothly and securely. They're very comparable to the regular one that my camera came with - same dimensions, weight, and clarity. I've spent most of the time so far using the polarizing filter out of the set, and it works great! I'm still a beginner, but I can really tell a difference in surface reflections in my photos. One thing to note is that I can't have my GoPro's protective silicone sleeve on while I'm using that specific filter though because the sleeve extends all the way to the edge of the housing, which covers access to the dial you need to spin to adjust the polarization.

The four filters come in a plastic latching case, snugly secured in foam. I found this really reliable and protective when I took them traveling because I could keep them in my backpack without worry. Very satisfied all around!

Very Nice set of filters for my Hero10. Fit Securely but easy to change especially with the grooves on the lens edges Love That feature!! Glass is Crystal Clear and image Quality is Amazing. Highly Recommend this set!

Nice set of twist-on filters - and they fit the Hero 11 Mini as well. Quality manufacturing, very nice glass. I find I get the best results going manual, not full auto. Three ND filters and one CPL. The circular polarizer is a must have when shooting anything with reflections - glass and water for example. 100% satisfied!

I was pleased to find this filter set for the GoPro 11, with its 3 different ND filters along with a circular polarizer that actually rotates for the best effect. Without the rotation feature, it really isn't a CPL in my book, so I was glad this tiny CPL filter has that ability and is easy to adjust. I have a "Mini" version, but the filters will fit both the mini and the standard size GoPro 11.

The fit is identical to the original GoPro filter that comes pre-attached to the camera. Admittedly, I had to search for how 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 does take a little force, but that's better than being loose. The filters go back on the same way, just be mindful of the two metal bars. It's obvious how to orient them once you see the bracket that holds them.

Having a series of ND filters can really open up some creative options, such as slower shutter speeds. A polarizing filter is an excellent way to help remove reflections on water and glass, as well as darkening the sky for better color saturation.

The construction of the filters themselves seems top notch and have a quality feel to them. This filter set comes in a basic, but very nice case that holds all four filters securely. The box is about the same size as a normal single filter case and won't take up much extra space in the camera bag. So where the GoPro goes, this filter set will go.

I really like the circular polarizing filter. The ND filters are a bonus for being able to add some motion blur and being able to get lower shutter speeds.
