ND FILTER
Reduces the amount of light entering the lens, thus decreasing camera shutter speed. Useful for situations where motion blur needs to be created (rivers, waterfalls, moving people) or large apertures must be used with flash to avoid overexposure.

They Work Great
I did plenty of research on YouTube to find the right ND filters and for the budget and quality I went with these and they work great. I haven't noticed any issues and am loving them!

Must have for the Photography gear bag !
Easy to install on the camera, pictures come out gorgeous and very easy to use. I like the fact that you don't have to continuously need to install and reinstall different filters. One is all that's needed - great product !

Filter has a smudge on the INSIDE. What?
My latest complaint with this filter is that there is somehow a smudge on the inside glass. It even looks like a finger print. I noticed while getting ready to film a wedding, cleaning all of my glass.Cons:- These don't get dark enough to keep your aperture wide open on a sunny day for video. At least at f/2.8- Mine somehow has a fingerprint or some type of smudge on the inside.Pros:- No loss in sharpness- Durable/Heavy Duty- The ring stops at the max ND level.I like these filters, but I do wish they got a little darker.
