This is a very good filter to have. This filter has 3 effects in one filter. It has black diffusion mist effect, variable ND filter and circular polarizer. The black diffusion mist is great for softening the highlights without losing to much sharpness. It's good to give a cinematic film look. The ND filter brings down the bright exposure from 1 to 5 stops. This may work outdoor during the day but the subject still needs to be under the shaded area because 5 stops may not be enough. The circular polarizer is great to reduce unwanted reflection and glare. It works well if there is water in the frame. This will reduce the reflection on the water.

Everything is in one. There is no need to unscrew or screw to make adjustments. I like that this filter has a friendly dial thumb that I can easily rotate to control how much stops I want. The built is a high quality one. The glass is a high quality one as well. The optical glass ensures excellent light transmission and clarity. The glass is scratch-resistant.

When I don't use this filter, I can remove this filter and put it in its beautiful filter case.
