DJI Mini 5 Pro takes really good pictures out of the box, but with the help of ND/PL filters, the recordings are even more professional. That's why I opted for the 6-piece set from K&F Concept. The filters were delivered in a flat storage box. The filter is easy to install, snap on, and you're done, meaning that you can also change it quickly at any time. I always use the ND/PL filters for photos and videos, whether for drones, system cameras and action cams. In this case for my new DJI Mini 5 Pro. Because this makes the colors come across even more effectively. When it comes to ND/PL filters, I usually use ND4PL, ND8PL and ND16PL. The ND32PL and ND64PL, in winter with snow/blue skies and in summer with clear sunshine. Also with waterfalls and clouds to make the quick camera movements softer and gentler. Everything else is then razor-sharp. It's best to try it out yourself and then compare the results. The quality of the materials, including the glass, is impeccable and the workmanship of the filters is good. They are easy to install, they hold reliably, fit snugly and the recordings become even more professional. With PL filters, the images also become more colorful and richer in contrast. Explanation of the ND filter: I use them for long exposure and depending on sunlight. This makes the recordings silkier. 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, as the image would be extremely overexposed or even completely white. The names for this set mean: ND4 = slowing down the shutter speed by 2 stops to increase the shutter speed ND8 = slowing down the shutter speed by 3 stops to increase the shutter speed ND16 = slowing down the shutter speed by 4 stops to extend the exposure time ND32 = Decrease the shutter speed by 5 stops to extend the exposure time ND64 Reduce the shutter speed by 6 stops to extend the Exposure time By using the various filters, you will quickly see how beneficial they actually are. Every professional works with such filters ;-) The polarization level can also be adjusted with these ND/PL filters, which has further advantages. I am very satisfied with this ND/PL filter set and would be happy to recommend the set. The price/performance ratio is in line with the good quality. Thank you so much for taking the time to read my review. I hope that I was able to help a bit with this.
