K&F is one of the better value price point companies in the world when it comes to making quality content creation accessories. I've got a lot of gear from K&F and it's all very good to excellent and sold at a killer price. These DJI Mavic 3 filters are more of the same--a great product at a great price. I've always been uncomfortable buying drone filters. Their functionality is obvious but there's several problems in theory. You're adding weight to a drone which at some point can become problematic. Then there's the issue of securing them to the drone--I don't really want to invest a ton of money in filters and have them end up in some farmer's field.

At this price, you won't even worry about the possibility that your filters might not be attached to your drone when it returns. These are very well made and high quality filters that cover a lot of basics. You get a ND8, ND16, ND32 and ND64 filter They're multi-coated, high quality optical glass with a thin aluminum alloy frame. The product description says that they weigh 4.6 grams which translates to a negligible weight of 0.16 ounces! That's a weight that your drone probably won't even notice.

Out of context, these are still above average filters. Factoring in their price they're amazing filters for the money. Highly recommended!

The K & F Concept ND filter set is rated in ND 8, 16, 32 and 64 for DJI Mavic 3 Classic.

The filters are delivered in a small plastic storage case. It contains the 4 filters, embedded in a foam rubber mold. Thanks to the foam rubber, they remain reliably in place and are well protected against scratches.

The filters themselves consist of a metal frame and tempered optical glass.
They are included in 4 different strength classes. For most uses, the filters should be sufficient to extend the drone's shutter speed as you wish and thus create a cinematic motion blur in the image. Or simply to be able to expose the image correctly.

The filters have a very good workmanship. They fit onto the drone's lens with millimetre precision. The filter holder snaps gently into place. The filters can also be simply turned down again.
I find it very good that the filters are made of metal. In addition, one weighs just 8g, which means that the flight characteristics of the drone are not changed.

The compensation is excellent, the filter has no color cast.

Conclusion
In my opinion, the K&F Concept ND filter set is a very good product. The filters are neatly processed + the set is cleverly put together. You won't take long exposures with ND256 or higher filters out of the air anyway, so I think the ND 64 is the all-purpose weapon for very bright environments or very long shutter speeds for motion blur.
At the time of my review, the price of the filter set is around EUR 50, -- which in my opinion is an excellent price/performance ratio.
I therefore give it 5 stars and hope my review was helpful.

K&F Concept isn't the most well-established gear maker on the market, but it's quickly become known as one of the better affordable options. The quality here is pretty close to what I expect from their full-sized lens filters, so that's reassuring.

My only real complaint is that it's hard to see the labels on the filters until after they're pulled out.

There seems to be an issue with all third-party Mavic 3 Classic filters, and not just with these ones in particular, where the filters are very tight going onto the camera. It's present in my Neewer filters as well, so at this point I'm convinced that DJI has given every accessory maker dimensions that are just close enough to work, but just wrong enough to make its first-party filters the only ones that are easy to use. So, instead of saying the filters are hard to insert, I'll just call them securely fastened in place.

This is such a great looking set of filters. The filters themselves look great before even mounting them. They have a nice weight to them and feel like they will last a long time. The plastic case they come in is great and feels like it will last just as long as the lenses. It’s slim design allows it to easily fit in any case or even in your pocket. They fit great on the drone I use and have greatly improved the images that I’ve taken. I also have to say that the packaging this comes in looks amazing. It feels professional from the moment you get it out of the box. This is a great price for 4 good lenses.

I recently bought a DJI Mavic 3 Classic, primarily for filming video. The Mavic 3 is great as it does have a physical aperture that can be used to have some control over the amount of light coming in, but as with any camera, it is limited. So in order to film at a cinematic frame rate and shutter speed like 24 fps and 1/50th sec shutter speed, I needed help, even on cloudy days. These ND filters do it and do it well.

The filters come in a nice plastic pack with firm foam cutouts for each filter that protect them well. The filters fit on the camera just as securely as the clear glass filter that comes with the drone. But it may take a little fumbling to get it to sit just right. And since the area of the ND filter area is slightly larger than clear filter, the extra filter area ensures that you don't get any vignetting (darkening around the edges) that you can often get with ND filters. Also, I did not notice any color cast.

If I had to complain about anything, it is the microscopic lettering used to label the filters. This is partially due to the thin frame so they don't have much to work with. But they could have used a little larger font for the sake of old guys like me. So keep a magnifying glass in your bag if you want to know which filter you're choosing.

Otherwise, K&F generally make good quality products and this seems to be as well. This is a good value.

The video sample was shot on a mostly cloudy day at 24 fps, 1/50 sec shutter speed, 400 ISO, f/6.3 with the ND8 filter.I recently bought a DJI Mavic 3 Classic, primarily for filming video.

I don't use ND filters all the time, but for those moments when exposure is up against its limit, such as snowy scenes on a sunny day, wheatfields highly reflective surfaces, you simply have to have them. I use my polarizer more than ND filters, but I always keep a set of these in my photo bag. As a few others have mentioned, they are a very tight fit, but you be rest assured they won't come loose in flight. If you don't already have a set, grab these. The price is good and the quality is first rate.

I found similar drone ND filters from NEEWER a few months back. These are just as good, from a less well known brand, especially here on k&f conceept.

They do what they say on the tin; dulling the amount of light coming through the drone lens at the f stops on the side of the filters.

The fit could be better; I am using a Mavic Mini 2. But great kit for the summertime and flying your drone.

These are so awesome! Now I think these are an absolute must, because they are a game changer. I really like how this comes with the different levels of filtration, because flying on a sunny day requires a much darker filter, while flying on an overcast day might only need slight filtration. They paid attention to the quality, and it shows! These are so nice!

I've had the DJI Mavic 3 Classic for a long time, mainly to shoot nice pictures and 5K videos while on vacation.

I filmed without filters for a while and was always amazed at the fluctuating quality.
What bothers me the most personally is that I can't properly film against the sun without the glare constantly interfering with the recordings.

The K&F Concept ND/PL filter set seems to be the solution to my problems.

Actually, I wasn't really aware that there was something like this for my drone.
But I wasn't really looking for it either, as I rarely travel with a drone.
You have to emphasize, of course, that the DJI recordings are simply very good even without filters.

But once you've started working with the individual filters, the sometimes extreme difference in the recordings becomes clear.

With the various filters, which are also made very precisely and without optical errors, the images become visually much softer and more uniform.

When shot in direct sunlight, the glare is not so extreme anymore, but rather soft and balanced.
In particular, images in snow or over water with strong reflections improve visibly.
This means I no longer have to edit my films later with my software to reduce reflections and glare.

The filters can be attached with a slight twist and are super secure!
Qualitatively, the filters could also be an original product!

Nothing significant has changed in terms of weight either, as the gimbal control still works very well.

I am 100% convinced of the product and of course I absolutely agree with the selling price of just 60€!

I had actually used the Neewer ND filters for my DJI drones and GoPro for years and was always satisfied with them. Now I've also received this one from K&F for testing my new Mavic. The delivery was done quickly thanks to k&f conceept.

The filters fit the Mavic 3, as is also available from Neewer. In terms of price, the two sets are not much different. K&F are a few euros cheaper, but also offers quasi-integrated polarization filters. The filters are all well made and sit firmly on the camera housing. Even with lots of action and turbulent scenes, you don't have to worry. The filters remain reliably in place.

The ND filters extend the exposure time in bright sunlight and the pictures simply look much better than without them. There are some good apps that recommend specific ND filters depending on location, season and sun position/time. Lens flares are also largely suppressed when shooting backlighting, which Neewer also does well.

The lenses are easy to clean and come with a case for transport. I can only recommend it. If you are looking for ND filters and don't need the polarization settings, you can also use Neewer. Neewer is on sale from time to time, but unfortunately I don't know about K&F yet. Since they're new to me.
