No problem for this filter that completely fulfills its task: color saturation, mastered reflections, vignetting effects ... The thinness of the frame makes it comfortable and avoids any problems with the super optics. Just a little flat but that does not concern the optical filter but (it's the same at Nikon or Canon!), The monrage a visor is made only on optics which has the effect of advancing front lens (in this case the filter) and thus reduce the effectiveness of the lens hood. Finally the filter being "at the bottom of the visor," turning its adjustment is not easy when the sun visor is in place. No problems with delivery, packaging and satisfactory period shortcut from that announced.
