I start with the filter so I have no point of comparison but they are screwed well and do their job well (although the polarizing filter removes reflections on the water for example, and the outer ring allows to turn easily). For the sun visor attention to me, it is not possible to use it at the same time that the filters would require a type of tulip HB 32 to secure it to the outside of the lens (bayonet fitting). Here, if you want to combine sun visor + filter, sun visor screw on the filter, then it too goes beyond the objective and seen on the frame. The only solution is to remove the filter and screw the screw inside the goal but we still see a small part of a wide angle.
