Easy to install, well made and also very nice to look at, in its protective packaging, I would say excellent value for money.
Fairly effective polarizer, no adjustments.

Diving straight into the meat of things, the difference these filters make to aerial photography is notable. The colors in the footage now pop with a vibrancy that was missing before. With the polarizing filter, reflections on water bodies that used to obscure the view are now pleasing to the eye, allowing for crisper images from above. The ND filters are particularly handy for those bright days when you need just a bit more control over the exposure without having to compromise on the depth of field. On a partly cloudy day, the ND8 is my go-to, while the ND16 is perfect when the sun is in full force. The lightweight nature of these filters means my drone handles as if they weren't there, which is crucial for delicate maneuvers. Cleaning them is a no-fuss affair, thanks to the coatings. They are reliable tools in the kit of anyone serious about their drone videography, elevating the quality of the footage substantially.

I’ve not had a bit of issue out of these. Fit is perfect, high quality. Great enhancement.

For me, they worked as promised. Nothing to worry about this product on my Air 3

The filters are as they explain, easy to switch out and durable.

If you want to shot videos with your Air 3 drone, and have them appear natural (or at least as natural as our movie-trained eyes allow), you need to use neutral density filters. I won’t explain the exposure triangle but if you don’t understand the relationship between aperture, shutter speed and ISO, you should learn this before using these filters.

These filters are designed for the DJI Air 3 and, as far as I know, only for that drone. They install on the drone with a twist, although it would have been nice if the manufacturer had included an instruction on how to mount and dismount the filters. I tested the density of the filters to insure they were 3, 4, 5 and 6 stops darker, and they were on the button. I also tested whether they were neutral density and found a slight shift to the red of about O.1 %. I regularly find this kind of a shift in even the best neutral density filters, so I was not concerned by it. If you are concerned than you probably know how to adjust for that in Lightroom Classic. Most videographers and photographers will be more than happy with the neutral nature of these filters.

I am unable to comment on the polarizing features of these filters. All of them bear the PL initials, but unlike most circular polarizers, these polarizers are not adjustable. In any event, I have found polarizers almost impossible to use with drones, whose relationship with the sun changes often, and in any event, is impossible to adjust while a drone is in flight. I don’t see a plus side to any polarizing features, but I don’t see a down side either.

I am using these filters with my Air 3 when I shoot videos and am happy with them.

Pretty much a must-have for good drone footage. K&F is delivering their usual good quality materials, performance, and a competitive price. This one is a win.

These filters are easy to install so you can quickly change them on the fly (pun intended). The glass is also clear with no distortion. K&F makes some quality filters.

This set of filters is compatible with DJI Air 3. The workmanship is of high quality and the adhesion speed is very fast. With this filter set, I can handle almost every possible situation (weather and light effects) and it is perfect for my DJI Air 3 drone. They are securely fixed and held in place during flight, ensuring stability and greatly improving the quality of my drone shots.

These artistic filters allow you some creative control over the video you are shooting, particularly where you can't process the video a whole lot before posting. The filter selection allows you slow down the shutter speed based on ND strength and has the added bonus of cutting down on glare with the built-in polarizer.

While you can usually achieve the desired effect you want with normal ND filters, it's good to have a polarized set like this on-hand to help tame the glare that can spoil some shots.

The filters look well-made and the filter glass seems to be free of aberrations, desirable factors for any optical filters.
