Very good for the price top. The processing is also in the upper range. I will buy more filters from the company.

Perfect, the adjustment is very progressive and practical, no chromatic aberration, sharpness is preserved. In short, nothing to say, it's an essential and very versatile tool, accessible to everyone. I recommend.

bought this adjustable ND filter to use with my Canon EF lenses on my trip. It worked like a charm and allowed me to capture some beautiful scenery!

I ended up with the K&F system and I have to say there is nothing wrong with it.
