Think of it as sunglasses for your camera
I heard a lot about ND filter but not ready to buy the really expensive one off the bat so based on the review I decided to go with this one. For the price the quality of the glass and coating seems amazing. I never had one so nothing to compare it with. I love that it has a variable adjustment for it, seems pretty neat.Having never own one I decided to go out to the local fishing pond and takes some pictures. I upload 2 photo one with the filter one without and i'm just amazed. The picture I uploaded are unedited right off the camera with and same settings. It brings a lot of color out with the filter.Pro:• Very inexpensive filter with amazing result• Great for anyone who is starting out• Quality glass and coating• Variable ND glass• Neatly PackagedCons:• Non at this time very happy so farIf you are just starting out and don't want to break the bank and just curious on how these things work with your camera i highly suggest getting these. For the price what you got to lose. If its something you might be interested in doing more with your photography skill by all means invest in the more expensive lens but as a hobbyist these are great.If you found my review helpful please hit the helpful button it lets me know my review might have helped you in some ways.

Way to dramatic photography
Initially I was skeptical about buying this expensive filter but still gave it a shot. The results are amazing, specially when you use a flash, the background gets dark and the pictures look dramatic. Needless to say that it will work great for long exposure shots too.

A
From 1-5 stops, there will be a slight X cross for lens under 24mm. An X cross will appear at the highest stop and can be removed by rotating the filter ring, which is a normal situation instead of a quality issue.

Tested with Nikon Z 7 and Nikor 14-30mm Sline, dark corners are not obvious for 14mm and no dark corners for 16mm.

As K&F Concept ND2-ND400 filters adjusts the amount of light that can pass through with polarizing glass, a colour cast can't be avoided for all the variable ND filters on the market. However, K&F Concept variable ND filters are made by the best coating technology, which reduces the effect of the polarizing film on image color. *Based on our professional test, the colour cast of K&F Concept ND2-ND400 filters is around 290k while the industry standard is 500k. 
A
To avoid dark corners, K&F Concept ND2-ND400 filters are designed in ultra-wide construction so the front side of the ND filter is one size larger than the camera lens. It is recommended to use a lens hood of a larger size. 
A
First, K&F Concept ND2-ND400 lens filter allows changing shutter speed based on the effect you want with the best sensibility and the same aperture. Second, K&F Concept ND2-ND400 lens filter allows creating a blurred background with a large aperture while the shutter speed remains the same. Third, K&F Concept ND2-ND400 lens filter is designed to prevent overexposure and maintain image purity and quality at the same time. *Like a zoom lens, the variable nd filters are suitable for multiple shooting situations. If you're looking for perfect image quality, a fixed ND filter is recommended.
