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.

I tried using the variable ND filters on the DJI Osmo Pocket 3, but found them too fidly. Instead I went for this 4 filter kit which works great. AND BONUS: You can stack these filters on top of each other! You can even stack the polarizer on top of the ND filters. PLUS the other thing I like about the K&F concept filters is, they have little indents on the side that you can get your fingernails into to place the filters on the lens and it also makes it easier to remove the filters as well. I tried the other brands, which are good, but they don't have these little finger nail indents. PLUS the camera can rotate the lens to the closed position with the filter on (However, it will not close with stacked filters on—>just one filter on)

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

The K&f Concept ND filters fit and finish for my DJI mini 4 pro are perfect. I highly recommend them.

I wanted ND filters for my DJI mini 3 Pro and this kit of 6 filters and propellers was exactly what I was looking for. Today was a very bright sunny autumn day and the light was too strong and harsh so I used these filters to get a good result and I'm happy they match my Mini 3. They come in a small plastic case to protect them and make carrying the kit easier. Very easy to put on, this was something I didn't think would be. I had to try them all on to see which would give the best result for that sunny day and there was one of the six that got me the image I wanted. If you are looking for ND filters for your mini I recommended them and you also get propellers.

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.

I had actually used the Neewer ND filters for my DJI drones and GoPro for years and was always satisfied with them. Now I have also received this one from K&F for my new Mavic to test. Delivery was quick thanks to Amazon.

The filters fit the Mavic 3, which is also available from Neewer. There is not much difference in price between the two sets. K&F are a few euros cheaper, but also offer quasi-integrated polarization filters. The filters are all top-quality and sit firmly on the camera body. Even with a lot of action and turbulent scenes, there is no need to worry. The filters remain reliably in place.

With the ND filters, the exposure time in bright sunlight is extended and the pictures simply look much better than without them. There are some good apps that recommend certain ND filters depending on location, time of year and position of the sun/time. Lens flares in backlit shots are also largely suppressed, which Neewer also does well.

The lenses are easy to clean and a case is included for transport. I can only recommend. If you are looking for ND filters and do not need the polarization settings, you can also use Neewer. Neewer is occasionally on sale, unfortunately I don't know about K&F yet. Because they are new to me.

The ND filters for the DJI Mavic 3 Classic drone of excellent workmanship, very easy to install and use and with excellent packaging.
I use it with my drone and the difference is remarkable. It eliminates digital over-sharpening, reduces contrast and allows you to reduce shutter speed. good investment
