My equipment: Canon 90D 18-135mm 3.5/5.6 USM lens

I really love this cover. I have never had an ND filter before, but I am completely blown away by the features of this one. As you can see from the photos I've uploaded, they work wonders in filtering out some of the harsh light from day shooting, they also let me capture a pretty awesome sunrise! I have not used them for motion photos, yet, as I typically do landscape photography, but they do help with pictures during the day to avoid having overly exposed areas in your pictures. The case it comes with is also top tier, made with nice leather and easy to remove from the package when you're looking to use it. I have not noticed any white balance issues with it, but I take all my photos in RAW format, so I don't usually pay much attention to my white balance (I fix that in the editing process). The lens itself is great quality, as well. It adjusts very easily and tethers nicely to my lens. I cannot speak highly enough about this filter, if you are shopping for something to bump your photography to the next level, this is an excellent place to start!
