was happy to find this filter set for the GoPro 11 with its 3 different ND filters and a circular polarizer that actually rotates to get the best effect. It really isn't CPL in my book without the rotation feature, so I was glad this tiny CPL filter had that capability and was easy to adjust. I have a “mini” version but the filters fit both the mini and standard sized GoPro 11. The fit is identical to the original GoPro filter that comes pre-installed on the camera. Admittedly, I had to look for a way to remove the filter as I didn't want to break my new camera, but it turns out it's a simple twist of the filter 90 degrees to remove it. It requires a little strength, but that's better than being loose. The filters go back the same way, just pay attention to the two metal rods. It's obvious how to line them up once you see the clamp holding them. A set of ND filters can really open up some creative options, e.g. B. longer exposure times. A polarizing filter is a great way to remove reflections off water and glass, and to darken the sky for better color saturation. The construction of the filters themselves appears to be premium and feels premium. This filter set comes in a simple but very nice case that keeps all four filters safe. The box is about the same size as a regular single filter housing and doesn't take up much extra room in the camera bag. So where the GoPro is going, this filter set will go.

The K&f Concept ND filters fit and finish for my DJI mini 4 pro are perfect. I highly recommend them.

I like to fly my drones early in the day when there aren't many people around, but the downside is that the sun is low in the sky and this gets worse in the winter months.
I've been thinking about trying ND filters for a while so I was delighted to have the opportunity to try this comprehensive set which includes ND4, ND8, ND16, ND32, ND64 and ND1000 and offers 2-10 stops of light reduction .
The filters weigh 1.1g, which is only 0.3g more than the detachable camera lens cover. This means that the total weight of the drone is still within the 250g limit for flight in A3.
Because the Mini 3 Pro camera has a fixed aperture, these filters provide an effective way to reduce shutter speed for more natural video capture.
The filters are supplied in a plastic housing with a click lock. The case is a bit larger than I would have liked, but it makes removing the filters easier and the empty space can be used to store the original frame or the removed filter.
The DJI Mini 3 Pro's camera is very small and I was afraid that if I took the cover off and replaced it with a filter I might damage it, but the whole process is pretty simple. However, I found it advisable to place the filters over my drone body so that if something falls it can be easily recovered.
Due to the current weather conditions and personal commitments, I have not yet been able to carry out a meaningful test. I will update this review when the opportunity arises.

Great filters for Mini 3 Pro. My favorite thing is that they stick to the gimble, they don't just slide over them even though you get 6 different colors from ND4 to ND1000 and they come in a protective case. They feel very good. The set even includes a set of mini 3 propellers, very happy with these ND filters

This filter kit for DJI Mini 3 Pro is ideal to give another dimension to enhance photos and videos.

The filters are easy to insert and feel secure when switched on. You will get 6 in total which are ND4, ND8, ND16, ND32, ND64, ND1000.

They each have different uses in different situations and weather conditions, e.g. B. to reduce reflections, glare, stop light reduction and improve image quality.

All in all, this is a quality lens set and a similar price to others on Amazon.

I hope you found this review helpful.

My review refers to the following product, which was made available free of charge as part of a product test:

K&F Concept Mini 3 Pro ND Filter & Polarizing Filter, 3-piece ND8, ND16, CPL Filter Compatible with Mini 3 Pro（Accessories：8*Mini 3 per propeller）

This Filter set consists of the following scope of delivery:

- 3 filter attachments (ND8, ND16 and CPL filter) in a padded transport box
- 2 propeller sets for Mini 3 Pro consisting of a total of 8 propellers
- a small screwdriver for mounting the propeller

Quality and handling of the set:

The Filters are stored in a padded, transparent plastic box and are therefore well protected against damage or dirt during transport.
The filters themselves are very well made and sit perfectly on the Mini 3 Pro gimbal. They are easily assembled. First you carefully turn the original cap of the gimbal anti-clockwise and remove it. Then you can put on the desired filter and lock it in a clockwise direction. The filters are printed on their frames with fine white lettering "Nano-X CPL" "Nano-X ND8" or Nano-X ND16" and are therefore very easy to distinguish.

The glass filters have a metal frame, yet they are extremely light (only 0.7 grams!) so they do not negatively affect the weight of the drone.
They are dustproof and waterproof, so they reliably protect the gimbal camera just like the original cover.

The two neutral density filters (also called gray filters) included in the set reliably reduce the light intensity that hits the sensor chip of the drone camera gimbal. This allows beautiful effects to be achieved when taking photos and videos.

The ND8 filter lets through 1/8 of the incident light, the ND-16 filter only 1/16 of the incident light. Beautiful effects (blurring, etc.) can be achieved with the exposure time.

The polarizing filter from K&F, on the other hand, ensures that reflections are reliably reduced. For example, in buildings with windows or on water surfaces. The polarizing filter also makes the green appear richer. This is particularly noticeable when filming or photographing forests or meadows. Even shots of the sky draw it much better. Since the Mini 3 Pro can pan upwards with the gimbal, great pictures of the sky are possible with the attached K&F polarizing filter. The K&F CPL filter can also be adjusted by adjusting the scale on the filter.

The enclosed 2 sets of propellers should enable a very low-noise flight when used. Since they don't differ much from the original in terms of appearance or construction, I keep them as a replacement.

Conclusion:
All filters in this set from K&F do their job very well depending on the area of ​​application and are easy to install or change. Therefore a clear purchase recommendation.

I rate the product 5 stars overall.

The K&F Concept Mini 3 Pro filter set arrives in a simple but visually appealing outer box.
One filter each is supplied in the following versions:
1x CPL
1x ND8
1x ND16
In addition, these are optimally stowed in a hard case with a transparent lid and molded foam padding.

On top of that, a propeller set consisting of 4 left and 4 right propellers, 8 screws and a perfectly fitting screwdriver is included.

The filters are a plastic version and advertised as such. They therefore hardly add any weight when they are exchanged for the protection of the drone lens. Thus, the 250g will NOT be exceeded!
They fit perfectly and without play on the Mini 3 Pro and the exchange is easy to do.

According to the manufacturer, the filters are made of multi-layer AGC glass. This is of the best quality and has optimal optical properties. The filters create exactly the desired effect and thus the video recordings are almost guaranteed to be perfect.

The propellers are also perfectly processed and are in no way inferior to the originals!

The filter set does it's job well, the propellers are just as top notch and I can't find anything negative about them. So I give it a full 5 stars and a clear buy recommendation.
