Maybe I've simply picked a better model, or the expectations of some other reviewers regarding the effects of a completely darkened ND3-1000 are simply too high. Of course, you can see optical effects when you set the ND filter to ND1000. It is not without reason that there are significantly more expensive ND filters, which then only cover the ND2-ND32 range. Everyone of us is looking for the egg-laying woolly milksow, but it doesn't actually exist.

I really like the Nano X series. I already own several filters in the series and am absolutely satisfied. You simply can't complain about the price called up and I personally find the effects of ND1000 also bearable. If I want to take particularly high-quality photos, for example with long exposures, then I use a fixed ND1000 filter anyway. However, if I'm traveling and want to be prepared for various situations, I'll take the ND3-ND1000 with me.

The filter is superbly made, and you can tell by the feel when you pick it up. I am also used to this processing from K&F Concept, because my tripod, lens adapters and other filters are also correspondingly well made. From my side, I can make a clear purchase recommendation if you are traveling with the right expectations for such a filter.
