77mm Kenko ND400 Filter - Used I bought this a while ago to adjust the light, but I'm selling it because I've changed lenses and no longer use it. There are scratches on the filter glass surface. I don't think it will affect the photos, but I'm just an amateur, so I can't be sure. I've used it a few times. Please understand that this is a used item before purchasing. Returns are a source of trouble, so I cannot accept them.
