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.

Apart from the fact that it is an excellent product, the customer support is simply absolute class, I have seldom been treated so reliably and kindly. High praise.

I tried it now on two different occasions and it is working very well for me. There is a very slightly color cast but easely to fix in Lightroom. Very happy with it.
