I have used ND grad filters for years on my SLR and DSLR cameras. I love scenery photography as opposed to portrait so always looking to sort out the difference in the light between the horizon etc. I live near the sea les that 300m away and walk along the cliffs regularly and don't take my DSLR with me when walking the dogs but always have my iPhone so any unexpected scenes are normally captured using the iPhone. This ND grad filter will come in useful. It fits over the lenses of my iPhone and helps sort out the difference in the light. Once clipped on it is easy to rotate the bezel to the setting you want using your finger. You have to ensure that you do not go past each of the stops or you will get leakage. SO my advise is to check before shooting that you are at the required stop. The other great thing about this filter is that it unscrews from the clip holder and can be screwed onto my 52mm lenses..Bonus... All in all this is a great little filter that I will carry around with me when out walking the dogs. We have a dog walking bag which has Poo Bags and drinking water etc so it sits in the side pocket of the bag in its case. so it is always there if we get a lovely sunset or something really nice to photograph on the sea or beach.. Get little gadget well worth the money highly recommended... As soon as we get anything really nice I will update this with the images...

My Mini3Pro works perfectly with these filters, the gimbal has no problems with them, the box for the filters is sturdy and there is no harm in having spare propellers. They can be changed easily. I don't notice any discoloration from the ND filters in the recording.

That says it all, this set is clearly recommended for the Mini3 Pro. But now the question: For whom are these filters recommended and what for?

Put simply, for anyone who doesn't want a video look but wants a film look on their recordings. What's the difference? In the so-called motion blur.

If you film with the drone on a sunny winter day with snow at noon, the camera adjusts itself to an extremely short exposure time due to the brightness. Each picture is only exposed for one thousandth of a second. If you then pause the video and look at the frames, every single frame is a razor-sharp photo, no matter how fast you're flying. It is this complete sharpness of the individual images that creates the video look that is often perceived as cheap.

Film look has motion blur, ie fast-moving elements in the recording, eg in the foreground when it is very close, are somewhat blurred in the individual images. This makes the rapid movement of objects in the running film smoother for the eye. In the single image, however, you can see the blurring of the fast-moving objects. This type of recording also corresponds more closely to how our eyes see. The picture becomes more natural.

To achieve this effect, you need ND filters. In order to achieve a film look, the rule of thumb is that you should double the number of frames per second and thus get the desired exposure time. So if you're shooting a video at 30 fps, the target exposure time is 1/60th of a second per frame. At 60 fps corresponding to 1/120th etc. This is a guide, you can experiment and get interesting results.

On our clear winter afternoon over snow, far too much light falls into the camera in a 60th of a second and the image is completely overblown. If you now put a high ND filter, for example 64 or even 1000 on the camera, the filter darkens the lens. This allows you to set the camera to a 60th exposure time, less light falls through the filter and the picture looks good... but with the motion blur caused by the 60th second exposure time. When which ND filter is right has to do with experience. In general, a higher number indicates a greater darkening of the lens.

So ND filters are needed if you want to make more natural looking videos that contain fast motion. A good example is when you fly over a rapeseed field with the beautiful yellow flowers at a height of only a few centimeters.

You have to decide for yourself whether you prefer a film look or a video look. Both can have their own appeal. But if you want a film look... I can recommend this filter set.

The best filter I've ever tried. Unlike the other filters I've tried, the image from a DSLR actually looks like film.

I purchased the K&F Concept 46mm Variable ND prior to my vacation in San Antonio and was super impressed with the performance of this budget filter!

Any aspiring photographer knows how difficult it is to film and shoot in bright sunlight without overexposing everything. This variable ND was the easiest answer to my run and gun film style while I was out shooting my vlog on my vacation.

I definitely recommend this product to people who need lens filters for their shots. Comes in a nice protective case and easily fits in my camera bag!

I simply copied the complete text from my YouTube video for you. Who prefers to see the video "Dji Osmo Action 3 I without ND filter in automatic mode and in PRO mode?" Enter on YouTube. Why do you need filters? It's a valid question, of course, who hasn't asked themselves that? I think everyone has stumbled across this topic and this question... The answer to this is very simple and surprising in view of this video - No, you don't need filters on a camera, it works without it...***but...It would be more an advantage as a disadvantage to have and use some. Anyone who works a lot on the water and beach, like me, or of course, like most of you, vacations there, quickly learns to appreciate filters. First, they are a very good protection against dust or sand from the beach. Of course, a filter also protects the lens, the lens in the camera. So much for the obvious, but the main job of a filter is to let less light through onto the sensor, it's like putting sunglasses on the camera. This has the advantage that longer exposure times can be achieved. It helps the camera to adjust and react faster in automatic mode when controlling the exposure time or white balance. Or if you prefer to work in Pro mode, you will quickly find that the exposure, the shutter, generally works better. In general, filters make the water smoother, and there are also fewer reflections. Or if you take great landscape shots, the sky immediately looks a little bluer. Filters also enhance the colors generally, making them more vibrant. DJI has, in my opinion, excellent colors and that in connection with a filter automatically makes the recordings **//LVL UP. This saves you having to color the film material because it comes out of the camera almost finished. Of course, the full professionals among you have other requirements and such, but I'm talking here for the normal user, like you and me... There are different ND filters. It starts **in my set at ND 4 and goes up to ND32. The ND4 filter lets only ¼ of the light through to the sensor and the ND32 filter 1/32. I use my filters like this... in the morning ND4, towards noon ND8, noon to afternoon ND16 and afternoon to late afternoon when the sun is very high ND32, and then in the evening just before the golden hour I go down again with the filter strengths. Over time, you will figure out when and where which filter is best used, is not witchcraft, even if many want you to believe that. Especially in summer or in winter when there is snow, I think it should at least be almost mandatory to have ND filters to have. If you like to film in Pro mode and work a lot with it, it is almost a must to work with filters alone because otherwise you cannot work with exposures in a meaningful way....

K&F ND filter, which allows you to film/photograph with a wide open aperture even in a very bright environment and thus the depth of field can be greatly increased even in well-lit situations. Conclusion: I recommend this filter to everyone for whom a perfect price/performance ratio is important!

I film and take photos on hikes and other activities. I need an ND filter for filming. I hate constantly turning the filter up and down to switch between filming and taking photos. The variable ND filter I used previously had 2 stops of darkening as the starting stage and produced a noticeable color cast. So it was useless for photography. With the ND-Vario variable ND VND filter, I can usually leave the filter on when taking pictures.

I was pretty late to jump on the ND filter trend because I'm an old photographer and still shoot film 90% of the time. In film, we learned how to make camera adjustments to achieve the same thing you would with these filters. Well, almost the same... I am shocked at how much easier it is to work with this variable ND filter in hard light and shoot long exposures!

One question I had was, "Does this work with film or pretty much just for digital?" and I'm happy to say that it does work for film, but I think its greatest strength is in digital photography.
This filter is one of the highest quality filters I've ever seen. It turns silky smooth, but has enough friction that it stays exactly where you set it and doesn't slip when you make another adjustment. I couldn't believe my eyes, but it also works as a mild polarizing filter. I was able to shoot in very bright and harsh sunlight and have an exposure of almost 2 minutes with the darkest setting, so I could see right through the reflection of the water. I have never been able to do that before!

I also love the little orange nub they call the "putter" on this filter. It just makes adjusting so much easier. I'm totally sold on using ND filters now, and since this one is variably adjustable, it's the only one I'll ever need! very happy with it!
