the filter is extremely clean and comes in its own bag with a magnetic closure. I didn't notice a color shift like with various other "plastic-based" products (but I don't use several filters in combination either).

If you take photos of sunrise or sunsets, this is the filter to use.

No color balance, true colors, does not change white balance. It's hard to scratch them (it's important when you're shooting outside). The mounting system is the best I've ever used. It is difficult to get loose, the rings are screwed on quickly and easily. Compared to other top brands NDG filters, K&F take the highest quality. I think they are the perfect choice for landscape photographers.

I mainly photograph landscapes and I have to say that I don't want to work without these filters anymore. The transition (soft) is just really nice and gives the picture so much more structure. The workmanship is also very high quality and justifies the price. Keep it up!

The quality of my recordings, for which I need a gradient filter, has improved significantly with this gradient filter from K&F. Even with problematic sun shots, it reduces unpleasant lens flares. great

These filters are an absolute highlight, convincingly good quality, everything fits perfectly, everything is high-quality and securely packaged and safely protected for transport in beautiful cases. The first tests are promising, but I currently don't have a suitable motif to test the full strength of the filters, but I'm absolutely confident that excellent and convincing pictures can be taken with them.

Absolutely amazing filters and a great price for glass, no color cast that I can see on any of my support images.

I used some pictures with this filer on a cruise in Daubei Doha etc. It definitely serves its purpose. The pictures are much more impressive with this filger.

What an excellent buy to clean up night photos outside of this filter is a must, I did two photo tests of the before and after the filter and it works !!!!

am a passionate landscape photographer as a hobby and have now switched from the screw filters to this rectangular filter system from K&F. The screw filters were all fine, but you don't have the option of attaching a graduated filter to the ND filter in order to achieve even nicer effects. It is mounted on the lens using so-called adapter rings, which are included in the most common sizes for lenses. After attaching the adapter ring to the lens, the filter holder is attached. This is secured by a small lever (spring-loaded) and later released again with this. Now you can slide the filter plates into the filter holder. This lifts a bit severely but it should also hold and must not wobble. It is also important to observe that the filter used is close to the lens so that no more light can penetrate between the filter and the lens, which could possibly ruin the recordings. In terms of quality, the system makes a good impression considering the price. The only thing I noticed negatively is that the filter holder has some play after it is placed on the adapter ring and why there is no adapter ring for a 55mm filter diameter in the set, I also ask. 55mm is a common diameter for lenses. I can highly recommend the K&F system for amateur photographers. The professionals will probably use filter holder systems from other manufacturers, but they also cost a lot more.
