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.
