K&F ConceptBlack Diffusion 1/4 Filter for DJI Osmo Action 5 Pro & Action 4, Black-mist 1/4 Optical Glass with 28-layer Coating Camera Accessories

This filter has a very nice effect, softening the highlights to create a more film like look without greatly affecting the mid-tones and shadows. It fits perfectly, by simply screwing into place on my DJI Action 4, so it is easy to swap out now as needed. The optical quality is very good and I managed to grab it on a sale, which made it pretty good value. It looks well made, so it should stand up to the rough and tumble of action camera use.I have to say that removing the original filter was a major challenge, until I learned the hairdryer trick to heat it from the side for about 30 seconds to loosen the original, then I was able to screw in this black diffusion filter without problems. Now it all functions as expected.

These filters take the digital edge away from your photograph or your video. Many action cams produce a picture that is over sharpened and difficult to look at as a result. This can be the jitter could be more obvious especially at the quicker shutter speed used by action cams.These mist filters reduce contrast slightly and allow the highlights to bloom into dark areas. The result is that the picture overall looks smoother and less ‘glassy.’ It looks more like a high-quality video than an edgy looking action cam video.The filter doesn’t cause light loss and in fact is dark places it could help because the overall picture appears lightened slightly. Highlights such as lightbulbs and candles flare rather nicely.This is a cheap filter that looks well-made and has the bonus that it screws on rather than push fits on so it’s on securely and will not get knocked off. Although it’s cheap the final result still looks great and the filter has a nice coating in order to keep flares at a minimum.I would love to see K&F produce a ND filter that also incorporates mist filtering because currently we can either use the ND or the Mist but not both together.A great piece of kit at a really good price.

The filters are made of high quality optical glass and have a 28 layer coating that reduces glare and flares. I have used the CPL and ND filters in various outdoor conditions and they have performed well. The CPL filter helps to reduce unwanted glare from non metallic reflective surfaces and the ND filters allow me to reduce the amount of light entering the camera sensor in bright conditions. The filters are easy to install and remove with the screw on mounting design. I have not noticed any effect on the image quality when using these filters. The optical glass ensures that the actual color of the image is restored. The filters are also waterproof scratch resistant dustproof and oil proof which gives me peace of mind when using them in harsh conditions.

I’ve been using the 1/4 Black Mist filter with my DJI Action 5, and it’s been a game-changer for my video quality. The filter adds a cinematic softness to highlights while retaining excellent contrast and detail. It’s especially useful for reducing the harshness of digital footage and creating a more organic, film-like look.What really makes this stand out is how well it pairs with my 1/4 Black Mist on my Sony camera. When I use footage from both setups, the visual consistency is seamless, making post-production much easier. The filter’s build quality is excellent, and it fits securely without adding unnecessary bulk to the compact DJI Action 5.For anyone looking to elevate their content with a touch of cinematic magic, this filter is a fantastic investment. Highly recommended for videographers and hybrid shooters alike!

They fit well. Maybe the case could do with being a little smaller for those with a limited space in their camera bag, but not so much an issue for me as I have room. I haven't tried them out yet, but as ND filters go, and a K&F brand, I am sure they will work ok.

Excellent quality and fantastic fit, very effective and give consistent colours

The filters are easy to attach and fit ideally on my camera. They are lightweight but feel durable, making them great for outdoor shoots. I use them in bright sunlight and overcast conditions, and they work amazingly well to balance the exposure and improve the overall image quality. This filter pack has made a big difference in my content creation.

I have these for my neo and they are spot on so getting this one was a no brainer. The quality as always is second to none and the effect it produces is spot on. I would recommend this brand all day long as they have nailed their filters.
