5 stars across the board
I love this filter. It's super useful for a variety of settings. The construction is sturdy and sleek, the picture quality is very clear with almost no distortion (I've noticed very slight vignetting when the sun hits it directly). Also comes with a case for when it's not in use, but since it's variable I usually keep it on a lense since there aren't too many situations where it is a hinderance.
