I've been a professional photographer for almost 10 years and have carried bags of ND filters around and wished for something like that. I was pretty surprised at how good that is. It saved me time and space in my camera bag. No more fiddling with toggle filters, now I just flip it. Well done too. Would definitely recommend.

Allows you to change the color density of the filter without constantly matching another filter. Screws onto the lens and is adjustable by simply rotating the front of the filter without changing the focus of the lens

The filters offer a very good price / performance ratio. However, the threads are so precisely fitting that you should turn the filters into each other very loosely if you don't need them, as it is very difficult to detach them from each other again. @Gobe: Perhaps a corrugated edge could help here.

The filters offer very good value for money. However, the threads are so tight that you have to twist the filters into each other very loosely if you don't need them, as it is very difficult to detach them from each other again. @Gobe: Maybe a wavy edge would help here.

This is the first variable ND filter I brought and it works. Seems well made and means I can use a lower F-stop. The only problem is that the filter has a slightly warm tone that you can easily correct by lowering the temperature afterwards. For this price I was expecting a color shift and am happy with it.

I love k & f concept filters. They are very well made from high quality materials. I don't look at other brands anymore as they are cheap. This is also my 4th purchase of their filters, which usually come in a well-made bag

I needed an ND filter in order to be able to take photos and / or film in spite of strong light and I am not disappointed with the result, I can only warmly recommend this product!

I just received the material and just did a couple of tests. The quality seems to be there. No image errors observed even at the maximum. Will be seen in real use in future versions.
