Comments about Hoya Hoya 58mm Half Neutral Density (ND) 4x Glass Filter:
Like all split neutral density filters you need a reasonably level horizon,otherwise you will be darkening items that should remain unaffected. Also,if using your camera's autofocus,you need to make sure that the filter's dividing line is horizontal when you get ready to shoot. With these caveats in mind, the filter will perform like a champ.
