This item is worth buying for the price, I tried it out and it seems to be working fine.

On wider lenses you get Xing which is typical of variable filters. No hard stops is a bit frustrating as you can turn past the lowest and highest settings.The filter is wider than the barrell of my 16-35 F4 which makes it unable to take the lens hood which is usually no big deal but don't expect to be able to use your filter and lens hood.

The filter does its job without much colour shift. Not bad for the price.

For me this filter fulfills its purpose and it is currently the best filter at this price

Fits perfectly to my Sigma lenses. The workmanship is very high quality. I find the padded box that goes with it very practical. The filter can easily keep up with the expensive ones.

Price-performance ratio. Doesn't have a dark "x" like other variable ND filters. Image quality is also very good. Would 100% recommend it. At this price you can't go wrong.

You can get into photography with a variable long exposure at an unbeatable price. Ideal for photographing waterfalls, rivers, the sea, clouds, this filter allows you to smooth the subject. With a single filter you can manage multiple opacities and thus a larger aperture of the lens. All you have to do is rotate the filter and in the end this filter is simply an indispensable accessory for the amateur photographer.
