in pI’m always dubious when it comes to filters as I have seen some cheap ones in that past that really degrade image quality. This neutral density film seems really good though.

It seems well made and screws on nicely on my canon EF-M lenses. The twisting adjuster works easily and smoothy and has the various stops marked on it.

Performance is really good too. There doesn’t seem to be a vignette or any other visible marks or patches on photos. The photos seem to be just as sharp and have the same quality as when shooting without the filter. I can’t tell any difference. It comes in a nice holder although this is way bigger then the filter itself.

The range of stops on the filter is good too and helps to slow things down for some major motion blur. It also works well for open aperture video. For the price I am really impressed with the quality and results.ast i got k&f ND filters and i wasn’t happy about them because the had horrible purple colour cast what i couldn’t get ride with photoshop, they were cheap. about £10 for 3 different ND filters with pouch. yeah... price does matter))) lol)) this one is NOTHING close to those what i use to have. it feels like i had ford ka and now i have ford mustang)))
ok...
i use 70-200mm is f4 and 10-18mm both have 67mm
it’s really easy to change from ND2 to ND32 don’t need to unscrew your ND filter from lens, just spin the circle.
there is NO COLOUR CAST. what is most important thing in ND filter. i would say i bought Nisi quality ND filter for twice less than Nisi.
comes in hard storage case not pouch. so when you throw your ND filter in your camera bag , you don’t have to worry about that it will smash. i would definitely buy it again.
