This is my third filter from K&F Concept and the last two I still use every single day (I'm a pro photographer/videographer) and love.

This one is a super powerful ND filter that goes from ND2 to ND400 which is an incredible range and can handle just about everything from day to day shots, daytime and super bright days to just leaving on the lens at night for evening shots and it copes with both admirably.

Comes in a very protective case, with a safety string if you want to use it, and a cleaning cloth - nice touch.

The quality of the build is as you would expect from K&F - first class and will last for years.

The images you get are very impressive and require little to no colour correction thanks to it's ability to not add too much yellow to your images like others do. This gives the shots a nice balanced colour straight out of camera.

Compared to others filters in the market of this quality I think this filter is a bit of a steal. They could easily charge a bit more for this one.

If you're in the market for an affordable, good quality ND filter then choose this one and you'll be really happy I think.
