There’s a fine rolling process on the rim of the filter to guarantee superior quality images. There are high levels of parallelism on the surface. There’s a superfine dull polishing and extensive knurling that makes sure that the frame won’t blanch due to repeated rotation. The ultra thinness of the filter frame helps avoiding vignetting on super wide angle lens.
All the materials used in this filter are non-hazardous and meet the requirements of European Union’s standards of environment protection. The black matt aluminium satin finish almite frame reduces reflections and the black rimmed glass component reduces light reflections around the filter edge. The filter case is also UV protected to further increase the filter life. The packaging is cushioned and is shock and moisture resistant.
