NiSi 55mm True Color ND-VARIO 1-5 stops (0.3-1.5), Variable ND ND2-ND32, Nano-coating with Optical Glass

One of the best filters I've used so far. We need more stops though please!

Optically this filter is good even very good but I found other brand for half the price of this nisi filter and very good with no dark X cross pattern too.I didn't like the silver bright ring on this nisi filter because it shouts from far.I purchased small insta 360 camera to be discret and not scare people in public while recording and this filter does just opposite with this no sense silver ring-no other brand do this.Turning the filter was not as smooth as expected for the price.protective cap also badly designed because you can't use the cap when this little turning knob is screwed to the filter.You have to unscrew little knob every time before putting filter plastic cover or you would have to cut the hole on one edge so the knob can have space to fit in.I didn't cut the plastic cover because I wanted to test it before and glad I didn't because I have returned this filter and bought other brand for half price and whole black.
