I thought that taking the Hoya, I might be avoid unpleasant surprises of Hama filters ... Well no! If you take a picture with a light source ... as you say, this source will be reflected (in reverse! Genre, if you take a picture inside with a window on the outside part, you will see the window and fair reflection next ...) and you will rot your photo. On a 35mm 1.8, reflections are more than visible, they downright spoil the shot. With flash ... it should be avoided completely. In short Disappointed ...
