I’ve been using this filter set with my Mavic 4 Pro for about two weeks, primarily to manage exposure and reduce glare in bright outdoor settings. The set includes ND8, ND16, ND32, and ND64 filters, which are simple to interchange—swapping between them in the field takes just seconds. Each filter is very lightweight, so there’s no noticeable effect on flight performance or drone stability.

The attachment system is particularly practical: you align and rotate to lock, and once secured, the filters stay completely stable during flights. They're a perfect fit - there’s no movement or wobbling, and the lens cover can be fitted over the filters when the drone isn’t in use, so I’ve often left a filter attached between shoots.

In actual use, the filters have delivered improved color and reduced glare without introducing reflections, distortion, or any loss of sharpness. The optics appear high quality; I haven’t seen any reduction in image clarity or unwanted artifacts. Cleaning is straightforward and similar to caring for any lens—just a quick wipe with a soft, lint-free cloth. I’ve found them easy to handle and attach, with no fiddly or frustrating moments in the field.

Overall, this filter set has performed exactly as needed for outdoor aerial photography, combining secure attachment, efficient filter changes, and consistently clean results.

Summary:

✅ Pros: Quick, tool-free filter changes | Very secure locking mechanism with no in-flight wobble | No detectable image degradation | Effective glare reduction and color enhancement | Lightweight and easy to handle

➗ Cons: None encountered during short-term use

Set of 4 K&F filters, perfectly compatible with the Mavic 4 Pro gimbal.

I have not noticed any deterioration in the behavior of the gimbal (which in itself is not always very stable in my specimen though), indeed perhaps the opposite thanks to the slower shutter.

The optical quality of the filters is excellent in almost all lighting conditions. Then it is clear that under certain circumstances it is still a glass that is added to the lens and by its nature (due to the shape of the support, mandatory due to the shape of the DJI gimbal) they are more exposed than the lenses themselves to being hit directly by sunlight. However, they do an excellent job of limiting glare or equivalent optical defects, contrast losses, etc. Great surface treatment, they do their job.

It is evident, both from the photos and in the use, that they have a different ND factor for the main lens and for the medium screen and the canvas, which I really appreciate because the basic brightness of the lenses is different, but I would like to have the specifications of the difference in absorption.

For the rest, it is an excellent filter kit: as always, the lenses do their best without anything ahead, but if the diaphragm is not enough or you intend to use medium canvas or canvas, the filters do their job. On the previous model, the Mavic 3 pro, I had those that came out of the fly more combo, and the quality seems to me to be perfectly superimposable.

Another excellent filter pack from K&F Concept. These fitted my Mavic 4 perfectly and are very high quality. I now use K&F filters on all of my camera gear and the filters produce excellent results. This set contains the ideal ND range for drone flying (ND8 / ND16 / ND32 / ND64). Fitting is a simply twist on/off and the excellent carrying case offers ample protection with a snap fastener.

I would rate the overall quality of these as excellent. Highly recommended.

I had the specific need for the CPL filter (circular polarizer) to take photos including bodies of water in the mountains and this filter proved to live up to expectations.
Since this is a filter for a high-end drone, I believe that those interested in such an accessory know exactly how to use it. I will therefore focus on my personal impressions of use.

First of all, it is very easy to remove it from the plastic case, but as far as the operations of adjusting the ring are concerned, I recommend using the included piece to avoid dirtying the lens. The thickness of the same ring, which slides just right without being too loose, is really very small, so care must be taken.
The assembly takes place through the tried and tested insertion and rotation system thanks to the three teeth that perfectly match the corresponding grooves placed on the drone's lens group. The operation is very simple and the assembly is absolutely firm.

As far as the results of the photos are concerned, I am certainly very satisfied. The reduction of reflections was effective and the color rendering did not suffer unwanted changes compared to using without filters. I used all three focal points of the drone and even with regard to the problem of distortions I did not find any particular anomaly.

In conclusion, a filter with excellent value for money, very light and easy to assemble. Absolutely recommended.

The DJI Mavic 4 Pro is already taking top recordings out of the box, but using CPL + ND filters, the recordings are exploited even better. That's why I chose this set from K&F. The filter set was delivered in a flat box. Which is also very handy for traveling and for storage.

Installing the filters is easy, turn the frame slightly to the left, remove and simply move the new filter to the left, then turn it slightly to the right and thus fix it. This makes it possible to change quickly at any time. I use the ND filters for photos and videos. With the ND8 filter, the video recordings get a little softer when the sun is shining, which comes across as a bit silkier. With the ND16, you can create really nice pictures. It's best to try out the various filters yourself and then compare the results.

In addition to ND filters, I use the CPL filter the most. This allows me to minimize reflections/reflections caused by water or glass and optimize contrast. It prevents details from being lost due to overexposure. A polarization filter (also polarizing filter for short) is a polarizer for light. For me, the CPL filter is a “MUST” for impressive recordings.
The outer ring of the CPL filter can be twisted, which has an effect on the polarization plane. I don't want to go any deeper into this matter, because that would go beyond the scope here... Just put it in zero position (line over line), that's right for the basic setting for reducing reflections.

The quality of the materials, including the glass, is good, the assembly is easy and the processing of the filters is flawless. They hold reliably, fit snugly and the recordings become even more professional.

Explanation of the ND filter: I use them for long exposure and depending on sunlight. This allows smoother recordings to be made.
What is a gray filter/ND filter? A gray filter is a filter where the entire surface of the glass is darkened so that less light can penetrate the lens.
It is therefore possible to select longer shutter speeds and achieve the corresponding effects, such as fog-like water or soft, elongated moving clouds. Without filters, this would not be possible.

About gray filters:
Gray filters are available in various variations with slightly confusing names from providers. I don't want to go into the various manufacturers here, just the names. I also had to work my way through it first, but basically, it's easy to understand.

The information for this set means:
ND8 = slowing down the shutter speed by 3 stops to increase the shutter speed
ND16 = slowing down the shutter speed by 4 stops to increase the shutter speed This allows you to take pictures with higher contrast and use the manual adjustment.

By using the various filters, you will see how beneficial they actually are.

I am satisfied with this filter set and can also recommend it because of the good price/performance ratio.

Thank you so much for taking the time to read my review. I hope that I was able to help a bit with this.

I added this filter set to my Mavic 4 Pro and it really improved the footage quality. The polarising filter cuts down glare nicely when flying over water or shiny surfaces. The two neutral density filters ND8 and ND16 helped smooth out the motion in brighter conditions and stopped everything looking overexposed. They attach firmly and stay put, even if you’re flying at speed. No change in colours or sharpness I can spot, just cleaner video. Good value for what you get and easy to carry along on shoots.

These K&F ND filters are a perfect match for the Mavic 4 Pro. They are easy to attach, lightweight, and don’t affect the gimbal balance. The quality of footage in bright conditions is noticeably smoother, with better colour and motion blur for video. Having ND8, ND16, ND32, and ND64 in one set gives full flexibility depending on lighting. A great investment for anyone serious about drone cinematography.

Flying the Mavic 4 Pro along the Irwell looks so much better when the brightest parts of the frame behave themselves. This K&F Concept pack provides ND8, ND16, ND32 and ND64 filters, each cut from AGC glass and sealed under a 28-layer nano coating. They snap into place with a reassuring click thanks to a three-point clasp, and nothing shifts even when the wind tears through Salford Quays.

Image quality is genuinely impressive. Glare is tamed and colours remain accurate with the ND16 and ND32 in place. Thanks to the hydrophobic layer, rain spots from a damp morning in the Peaks wipe away in seconds, saving a lot of faff while out in the field. Of course, it is not perfect. Those tiny metal clips are fiddly if, like me, you have hands the size of paddles, and the ND64 adds a faint warm cast that needs a quick tweak in post. The storage case also feels rather flimsy and could do with firmer padding.

Even with those niggles, the set deserves a permanent place in my flight bag. It controls light reliably, copes well with rough weather and adds next to no weight, so the drone’s battery hardly notices at all.

These ND filters fit the Mavic 4 Pro perfectly and snap into place without any fuss. The optical glass quality is excellent, providing clear, balanced images even in bright conditions. The 28-layer coating helps reduce glare and reflection, keeping footage sharp and natural-looking.

My brother used them during a shoot on a sunny day and noticed a real improvement in exposure control and motion blur. They feel well made and come in a compact case for easy transport. A great little kit for drone users wanting more control over their footage.

I’ve been using this K&F Concept ND Filter Set (ND8, ND16, ND32, ND64) with my DJI Mavic 4 Pro for the past few days, and I’m genuinely impressed with the quality and performance. The filters are extremely well made, they feel durable yet lightweight, and the overall build quality is excellent. The material used has a premium finish, and the filters slot securely onto the camera without affecting the gimbal’s balance.

The clarity and sharpness of my footage have improved noticeably when flying in bright daylight. The 28-layer multi-coating on the optical glass does a brilliant job of reducing glare and maintaining accurate colours and contrast. The range of filters in the set gives me flexibility for various lighting conditions, allowing me to shoot with more cinematic shutter speeds even under harsh sun.

The filters come in a compact, well-designed plastic case, which makes them easy to carry and store safely. I also appreciate the inclusion of a small cleaning cloth, a thoughtful touch that shows attention to detail.

One small downside is that the case could be slightly more rugged, while it does the job, a more protective pouch or shockproof box would’ve been ideal for travel. That said, at this price point, the overall value is superb, especially considering the optical quality and usability.

In short, this filter set exceeded my expectations and is now an essential part of my drone gear. Perfect for hobbyists and professionals looking to enhance their aerial photography and videography in a wide range of lighting environments.
