The DJI Mavic 3 Pro already takes perfect pictures, but using ND/PL filters, the images are even more contrasting and reflections are minimized. That's why I chose the K&F Concept set. The filters were delivered in a storage box.

It is easy to assemble, turn the frame slightly to the left, remove it and simply place the new filter on it offset to the left, then turned slightly to the right and it is thus fixed. This makes a quick change possible. I generally use the ND/PL filters for photos and videos. Because this makes the colors come across more effectively and better. When it comes to ND/PL filters, I usually use ND8PL and ND16PL. ND32PL and DN64PL when it is extremely bright, in winter when it is snowing, on days with cloudless skies and clear sunshine. Starting at ND32PL, the filter softens the rapid movements of waterfalls and clouds, which comes across as silky. Everything else is razor-sharp. It's best to try it out yourself and then compare the results.

The quality of the materials, including the glass, are impeccable and the workmanship of the filters is good. They are easy and quick to apply, they hold reliably, fit snugly and the images are much more professional.

The PL filter minimizes reflections and reflections. In addition, the images become more colorful and richer in contrast.
Explanation of the ND filter: I use them for long exposure and depending on sunlight. This allows you to take softer shots.
What is a gray filter/ND filter? A neutral density filter is a filter where the entire surface of the glass is darkened so that less light can penetrate the lens.
For example, it is possible to select longer shutter speeds and achieve the corresponding effects, such as fog-like water, or soft, long moving clouds. This would not be possible without filters, as the image would be extremely overexposed or even completely white.

About gray filters:
Gray filters are available in various variations with confusing, different names, from different manufacturers. I don't want to talk about the different manufacturers here, just the different names. I also had to read through it first, but basically, it's easy to understand.

The names for this set mean:
ND8 = shutter speed slowdown by 3 f-stops to extend shutter speed
ND16 = shutter speed slowdown by 4 f-stops to extend shutter speed
ND32 = shutter speed slowdown by 5 f-stops to extend shutter speed ND64 = shutter speed slowdown by 6 f-stops to extend shutter speed This allows Create scenes very effectively and effectively
.

By using the various filters, you will see how beneficial they actually are. Every professional works with such filters ;-)

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