Like many action camera enthusiasts, I used to struggle with getting great shots in bright, sunny conditions. The footage would often look washed out, with blown-out skies or choppy video due to fast shutter speeds. It was incredibly frustrating to miss capturing those vibrant colours and smooth motion just because the lighting wasn’t perfect. Solving this problem was crucial because poorly exposed or overly bright footage is incredibly difficult, if not impossible, to fix in post-production, significantly limiting the quality and usability of your creative projects.

Key Considerations Before Purchasing Action Camera Filters
Action cameras are built for capturing dynamic moments, often outdoors under varying light conditions. This versatility, however, can be their weakness when faced with bright sun or reflective surfaces, leading to overexposed images, washed-out colours, and a lack of desired motion blur in videos. This is where filters for action cameras become essential. Someone seeking to buy filters is typically an action camera user who wants more creative control over their footage, aiming for a more cinematic look, vibrant colours, or simply correctly exposed images in bright environments.
The ideal customer is someone who films outdoors frequently, whether it’s for vlogging, sports, travel, or any activity where sunlight or reflections are a factor. They understand basic photography concepts like exposure and shutter speed and want tools to manipulate these aspects. Conversely, someone who only uses their action camera indoors, primarily in low light, or who is perfectly happy with the camera’s automatic settings might not need a comprehensive filter set. They might be better off investing in lighting equipment or simply relying on the camera’s built-in capabilities. Before buying filters for your action camera, consider the types of conditions you typically film in (bright sun, cloudy, water, snow), the effects you want to achieve (motion blur, colour saturation, glare reduction), the compatibility with your specific camera model, the quality of the optical glass and coatings, the ease and security of attachment, and whether you need a full set or just specific filters.

Introducing the K&F Concept Filter Set
The K&F Concept 6-Pack Filters for DJI Osmo Action 5 Pro, Action 4 is a dedicated filter kit designed to give users of these specific action cameras greater control over their image capture in various bright lighting scenarios. This set promises to help you achieve balanced exposure, rich colours, and cinematic motion blur by managing the amount of light entering the lens and reducing unwanted reflections. The kit includes a CPL filter, and five Neutral Density (ND) filters: ND8, ND16, ND32, ND64, and ND256, providing a wide range of light reduction options. Compared to using no filters, or perhaps just a basic UV filter, this set offers a significant upgrade in creative possibilities and image quality control. It’s specifically tailored for the DJI Osmo Action 5 and Action 4, ensuring a perfect, screw-on fit unlike generic or magnetic filters that might not offer the same security or compatibility. This set is definitely for the Action 4/5 user who is serious about improving their video and photo quality in diverse outdoor conditions. It’s probably not necessary for someone who only uses the camera indoors or for simple point-and-shoot footage without regard for light control or effects.
Here’s a quick look at the pros and cons:
Pros:
* Comprehensive set covering a wide range of lighting conditions (ND8 to ND256 + CPL).
* Made from premium AGC optical glass for excellent clarity.
* Features a high-quality 28-layer nano-coating for durability, water resistance, and low reflection.
* Secure and reliable screw-on design tailored specifically for the Osmo Action 4/5.
* Lightweight design that doesn’t impact camera performance or stability.
Cons:
* Rotating the CPL filter might potentially compromise the camera’s inherent water resistance slightly (though the filters themselves are waterproof).
* The included case, while protective, can be a bit bulky if you’re only planning to carry one or two filters.
* The smooth edges can be a little tricky to grip and unscrew if your fingers are sweaty or wet.
Diving Deep into Performance and Practicality
Having used the K&F Concept 6-Pack Filters for DJI Osmo Action 5 Pro, Action 4 for quite some time now, I can genuinely say they’ve become indispensable tools in my action camera bag. My primary use case involves filming outdoor activities, often in bright conditions, and these filters have consistently helped me achieve results that simply weren’t possible before.
The Power of ND Filters: Taming the Sun and Achieving Motion Blur
The core of this kit for many users will be the Neutral Density (ND) filters. This set provides ND8, ND16, ND32, ND64, and ND256 filters. In plain terms, these are essentially sunglasses for your camera lens. An ND8 filter reduces the light by 3 stops, an ND16 by 4 stops, ND32 by 5 stops, ND64 by 6 stops, and ND256 by a significant 8 stops. What this allows you to do is maintain a slower, more cinematic shutter speed (like 1/60th or 1/120th of a second for video) even when filming in bright sunlight, which would normally force your camera’s shutter speed to be very fast (e.g., 1/1000th of a second or faster).
Why is this important? For video, a slower shutter speed helps introduce motion blur, making movement look much smoother and more natural, like you see in movies. Think about filming yourself skiing or biking down a trail on a sunny day. Without an ND filter, the fast shutter speed would freeze every frame, making the motion look jerky. With an ND filter, you can slow the shutter down, allowing the subject (or the background as you move) to have that pleasing blur that conveys speed and fluidity.
The range of filters provided here is excellent. On a moderately sunny day, the ND8 or ND16 might be sufficient. For very bright, direct sunlight, or filming on snow or sand (which are highly reflective), the ND32, ND64, or even the ND256 become essential. I’ve found the ND32 particularly useful for achieving a noticeable motion blur effect on fast-moving subjects while still keeping the overall exposure balanced under moderately bright conditions. The ND256 is almost extreme, perfect for very specific use cases like capturing ultra-long exposures in bright daylight for a milky water effect, although I find myself using the lighter NDs more frequently for video.
Beyond motion blur, these ND filters are crucial for simply getting a correctly exposed image or video. Action cameras often struggle with dynamic range, meaning they can’t capture detail in both very bright highlights (like the sky) and dark shadows simultaneously. In bright sun, the sky can easily get “blown out” – becoming a featureless white area with no cloud detail. By reducing the overall amount of light with an ND filter, you bring the bright parts of the scene within the camera’s manageable range, allowing it to capture detail in the sky and maintain proper exposure everywhere else. I’ve seen a dramatic improvement in the quality of my landscape shots and outdoor vlogs since using these filters, avoiding those frustrating blown highlights.
The Versatility of the CPL Filter: Reducing Glare and Boosting Colour
The included CPL filter (Circular Polarizer) is another incredibly valuable tool in this kit. While ND filters control the *amount* of light, a CPL filter controls the *type* of light – specifically, it filters out polarized light. What does that mean in practice? It drastically reduces reflections from non-metallic surfaces like water, glass, leaves, and even painted surfaces. This is incredibly useful for filming near water, allowing you to see beneath the surface instead of just capturing glare, or shooting through a window without catching your own reflection.
Furthermore, a CPL filter can make colours pop by cutting through atmospheric haze and surface glare. Blue skies become deeper and more vibrant, and green foliage looks richer and more saturated. I’ve used the CPL filter extensively when filming near lakes and rivers, and the difference in clarity and colour is remarkable. It truly helps capture more of the scene’s useful dynamic range and detail. You simply rotate the outer ring of the CPL filter until you see the desired effect (minimum reflection or maximum colour saturation).
One thing to note, as highlighted in some user feedback, is that using a polarizer on a very wide-angle lens, like that on the Osmo Action, can sometimes result in an uneven sky effect where the polarization is stronger in some parts of the frame than others. This is a physical property of polarizers, not a flaw in the filter itself, and is usually manageable by rotating the filter to find the most pleasing balance or by being mindful of your composition.
Premium Construction: Optical Glass and Durable Coating
The quality of the materials used in these filters is immediately apparent. They are made from premium AGC optical glass, which is essential for maintaining image sharpness and clarity. A poor-quality filter can introduce distortions or colour casts, negating the benefits of using one. I haven’t noticed any degradation in image quality or undesirable colour shifts when using these K&F Concept filters.
Crucially, they feature a double-sided, 28-layer nano-coating. This coating is multi-functional. It reduces reflectivity (minimizing flare and ghosting), makes the filters water-repellent (water beads up and rolls off, essential for action cameras used near water or in rain), and makes them scratch-resistant, protecting your investment and the filter’s performance over time. In my experience, the water-repellent coating works very well, making them easy to clean even after splashes or getting caught in light rain. They’ve held up well to regular use and being carried in my gear bag, showing no significant scratches.
Secure Screw-On Design
The screw-on design is a major plus for action cameras like the Osmo Action 4 and 5. It feels incredibly secure. Unlike some magnetic systems, you have peace of mind knowing the filter is firmly attached and won’t accidentally pop off during vigorous activity like mountain biking or surfing. Installation and removal are straightforward, simply unscrewing the camera’s original lens protector and screwing the desired filter into its place. While the edges are smooth, making them slightly difficult to grip if your fingers are wet or cold, it’s a minor inconvenience compared to the security the screw-on provides. The filters are also lightweight, ensuring they don’t add unnecessary bulk or affect the camera’s balance or performance.
Overall, the combination of effective light reduction, glare control, premium materials, durable coatings, and a secure design makes this filter set a worthwhile investment for anyone serious about getting the best possible footage from their DJI Osmo Action 4 or 5. They provide the necessary tools to overcome challenging lighting conditions and unlock creative possibilities like cinematic motion blur and vibrant colours that are difficult to achieve with the camera alone.
What Others Are Saying
After checking out reviews from other users online, it’s clear many share my positive experiences with these filters. People consistently praise the visual clarity and sharpness they provide, noting how they enhance filming without negatively impacting image quality. Many users specifically mention the benefits of the ND filters for achieving smoother video with motion blur in bright light, much like using sunglasses for the camera. The perfect fit for the Osmo Action 4 and 5, the perceived quality of the optical glass, and the secure screw-on attachment are frequently highlighted as major positives. Users also appreciate the ability of the CPL filter to reduce reflections and boost colours, especially when filming around water. Overall, the sentiment is very positive, with many recommending the set for its effectiveness and durable construction.
