Good quality of the filter. Use this filter for landscape photography am very satisfied.

Love this tripod very sturdy and good if you want to use it for bird photography as I do as well as my landscape photography

I had never owned a K&F Concept brand filter before and was pleasantly surprised when I first used it in my landscape photography. The reverse graduated ND filters from the popular brands of photographic filters tend to be quite expensive, and this one in particular is less expensive and produces results equal to and even better than those of the most reputable filter brands. It is made of glass, which is an advantage over resin filters because it does not scratch as easily. I really liked the filter cover, which is made of leather with interior protection. In short, I liked this filter very much and I am sure that I will use it very often in my landscape photography.

I have now used the filters a few times for landscape photography and am very satisfied with them. They are easy to screw on and off, nothing gets stuck. I am also very satisfied with the picture quality. For me as an amateur hobby photographer I think it's great with a very good price-performance ratio.
There may be even better and higher quality and I don't know what kind of ND filters, but I'm completely satisfied and would buy them again at any time! Especially since they are light compared to other systems and do not take up a lot of space when travelling, which is an important criterion for me.

Great for that smooth water effect in landscape photography. The filter is well made and I found it works very well.

A must for landscape photography. The effect is particularly noticeable in wide-angle shots. When the sky is darkened as a result, clouds stand out particularly vividly. Exposure corrections when taking the picture can be almost completely avoided.

Excellent high quality glass filter for landscape photography.
I only use K&F Concept filters because there is no colorimetric drift!
This allows you to control large variations in light and avoids the need to perform bracketing and other tedious software manipulations.
I highly recommend this product.

Great piece for landscape photography. Variable ND without "shadow cross", clean in both areas. The polarizing filter works great, and if it gets too bright you'll love the ND, stepless control. Used on FZ200.
