This isn't the latest and greatest. Certainly not going to put it up against the new Peter McKinnon ND Filter but for the money I'm quite pleased.

Pretty cool filter for the money, got it instead of getting another tiffen filter and it works very well. I would recommend this if you are using it on the Sony 18-105mm lens. It’s not built has “heavy duty” as my other tiffen filters but does the job. This 18-105mm is a lens I don’t use very often really only for travel so it’s worth it if you are doing vlogging and want to stay on the inexpensive side.

Intéressante formule pour un filtre ND (Densité neutre) il combine toute une gamme de densité en un seul filtre. Intéressant et économique.

...it flairs too easily with any light forward of 180 degrees, making a lens hood mandatory... but you cannot use a standard lens hood with a variable ND filter of this design. Other than that, the colour shift is neutral as it should be, and the range is very good. I predominately use this for video work and its is performing well in that capacity. I have not tried it with long exposure still work, but experience suggests this is not for that kind of photography. If you want to do long exposures, invest in a good Lee or similar square photography filter, not a circular variable like this.

I bought this variable filter for my Canon 18-200 lens. This is my “go to, do it all” during the daytime lens and it’s must have for daytime long exposures

First variable ND filter purchased (all others I have had have been static) and what a difference it makes!So easy to move around, and not having to carry more than one per lens is a real space-saver in the bag!I've experienced no false colour or the infamous X on any images (although I don't use this all the way closed!)Comparing it to a friends premium ND (I won't mention the brand), I could not see a difference at all in image quality. However, the premium ND was a bit stiffer to move around, so it felt like it would stay exactly where left. The K&F one does feel like it may loosen up over time, although this hasn't happened yet a few months in!

This took my video and photography game to another level. I can now use what ever settings I want without no problems.
