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

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

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.

K&F Concept Mini 3 Pro ND Filter

Good contrasts are the basis for beautiful, rich images. With the ND filters from K&F Concept you get a very high-quality and good set. The filters can be attached easily and without any problems. I could not determine any negative image effects such as color fringes.

If you want to take great high-contrast pictures, you can use the ND Filter Set from K&F Concept. Good quality, versatile and good price.

Suitable for 1 Mavic Mini 1. There were no problems with the gimbal. Perfect !

Perfect to complement my Mavic Mini !!

The K&F Concept ND filter set is rated in ND 8, 16, 32 and 64 for DJI Mavic 3 Classic.

The filters come in a small plastic storage case. Inside are the 4 filters, embedded in a foam rubber mold. Thanks to the foam rubber, they remain reliably in place and are well protected from scratches.

The filters themselves consist of a metal frame and tempered optical glass.
They are included in 4 different strength classes. For most purposes, the filters should be sufficient to be able to increase the shutter speed of the drone as desired, thus creating a cinematic motion blur in the image. Or simply to be able to correctly expose the image.

The filters have a very good workmanship. They fit the drone's lens with millimeter precision. The closure of the filter holder snaps gently into place. The filters can also be easily turned down again.
I really like that the filters are made of metal. In addition, one weighs just 8g, which does not change the flight characteristics of the drone.

The compensation is excellent, the filter has no color cast.

Conclusion
In my opinion, the K&F Concept ND filter set is a very good product. The filters are cleanly processed + the set is thoughtfully put together. Long exposures with ND256 or higher filters will not be done from the air anyway, so I think the ND 64 is the all-purpose weapon for very bright environments or very long shutter speeds for motion blur.
At the time of my review, the price of the filter set was around EUR 50, which in my opinion represents an excellent price/performance ratio.
So I'm giving it 5 stars and I hope my review was helpful.

The K&F Concept ND filter set is compatible with the DJI Mavic 3 Classic. The set of 4 includes four ND filters (8, 16, 32 and 64). The workmanship is of high quality and the attachment is very quick. With the filter set you are actually equipped for almost all eventualities (regarding the influence of light and weather conditions). You can shoot great videos or take pictures that are much better in terms of quality, color and light play than without a filter.
