Lots of vignetting even at lowest setting. As you get halfway through the darkening you start getting blotches. At full darkening there is a dark visible X in the picture. I am very curious how this filter go so many positive reviews. I find it unusable. I am returning it and will look for something more expensive that works or simply go for fixed ND filters

Great ND filter BUT will not work with lens cap. Once I put it on my Sigma 24-70, the lens cap that came with it would not work. The filter itself is larger and will have to grab one of those rubber caps. Sort of annoying but great results!

I ordered this filter and it arrived on July 7th. I used it one time to take pictures. I kept it in my camera bag in its case with my camera gear. I tried to use it yesterday and it only tints portions of the lens making the pictures unusable. This filter was never dropped or tossed around or treated rough in any manner.

Very nice filter. Seems to be no difference in image quality. I attached an image I got with the filter attached. It is fitted over a hoya UV filter as well.The lens rotates smoothly and has marks so you know with you are at the min or max.It’s nice to have one on your lens for outdoor shoots so you don’t have to keep swapping out different filters with lighting changes.
