This is a good starter filter kit for your DJI OP3 kit. It includes 3 fixed ND filters (16. 64, 256) and a CPL filter. They fit the OP3 perfectly and you can close the gimbal head with the filter on. K&F is a go-to for filters for all photo/video needs and this set is up to par with their quality standard. Ideally, a lower ND filter might have been a better option for this kit as I think an 8 might see more use than the 256. The only other filter you might want to consider is a black mist filter to soften the sharpness that the OP3 provides. Overall it is a good value and another great kit from K&F.

Bought this kit for my DJI Osmo Pocket 3, and it has been a game changer.
The ND gives amazing control over light exposure, allowing me to shoot in many different lighting conditions without compromising shutter which really helps the image.
The black mist diffusion does add a cinematic touch, softening the highlights and giving the footage a professional look.
It's suprisingly easy to attach magnetically and the build quality is top-notch.
Highly recommended!

The K&F Concept Blue Streak Filter for DJI Osmo Pocket 3 is a creative tool designed to enhance your video production with cinematic blue streak effects without post-production.

Thank you for reading my honest review, I hope you found it helpful! :)

Bought the polarizer for my DJI action camera, filter was within expectation.No risk of loosing it when camera in use.

Good product quality cpl filters & easy to use for my DJI Osmo Action Camera.

perfect, easy to install, good quality

The DJI Action 3 camera already takes really good pictures by default, but using ND filters makes the pictures even more intense. The set was delivered in a practical box, ideal for storage on the go.

A CPL filter is used when pictures are to be taken despite strong sunlight and reflections from water or windows. This prevents details from being lost due to overexposure. A polarizing filter (or polarizing filter for short) is a polarizer for light. Polarizing filters are known to be a "must have" for every photographer.

The filters CPL + ND) are only screwed, like the original, so a quick change is possible. The CPL filter is my favorite for photos and videos, whether with my drones, my DJI Pocket2 and now also with the Action 3. Because it gives the colors more contrast and minimizes reflections considerably. The ND8 and ND16 are often used for the ND filters. The ND32 when it's extremely bright, in winter when it's snowing, on days with clear skies and clear sunshine. The ND 64 softens the fast movements in waterfalls and clouds, which comes across really well. Because everything else is razor sharp. Try it yourself and compare the results.

The quality of the materials is impeccable and the processing of the filters is perfect. The attachment is easy, they hold reliably, fit exactly like the original. The filters are also tight underwater, which I tested yesterday in a body of water with a stick extension.

Explanation of the ND filter: I use them for long-term exposure and depending on the sunlight. This allows you to take softer shots. For example, gently blurring waterfalls and clouds.

What is a neutral density filter/ND filter? A neutral density filter is a filter where the glass is completely darkened so that less light can enter the lens.
So it is possible to choose longer shutter speeds and to achieve the corresponding effects, such as foggy water or soft, long-drawn-out clouds. This would not be possible without a filter, as the image would be extremely overexposed or even completely white.

I am very satisfied with this filter set and can recommend it unreservedly.

Thank you for taking the time to read my review. I hope that I could be of some help.

As with other cameras, you should use filters with the Osmo Action 3 in order to achieve the best possible image quality.

To change, the original lens cover is removed and the desired filter is screwed on. The edge of the filter is ribbed and therefore handy.
Each filter is identified by its designation in white letters on the edge.

Conclusion: very stable and high-quality filters
