Mentierer CPL HD filters feature a special professional design. The aluminum frame with a diamond pattern provides a professional appearance and a robust multi-coating to reduce unwanted reflections. The ultra-matte black coating on optical glass with original Japanese polarizing film ensures extreme convenience.

When using a filter, an almost invisible illumination is achieved. This way, the light source, usually a reflection of the lighting system, can be completely adjusted and made practically invisible. When photographing objects behind glass, such as in a museum, the mirror effect of the glass can be suppressed with a polarizing filter. Additionally, a polarizing filter can enhance the visibility of fish and plants in a pond, which is nearly impossible without a filter. Another effect of using a polarizing filter is that a cloudy sky gains much more contrast. These effects depend on the angle at which the polarizing filter is used.
