Made from extremely robust and light-transmitting Gorilla Glass and additionally sealed with a coating, this professional polarizing filter reduces unwanted reflections and glare, resulting in more intense colors. You will be ready to go immediately with the Professional Rectangle Filter Mark II Soft GND8, whose intensity of 3 stops is excellent for balancing brightness differences in the subject that the camera electronics can no longer handle satisfactorily. You can continuously adjust the soft graduated filter in the holder to give your landscape and architectural shots the desired mood. Your new Rollei professional filter holder fits comfortably in the sturdy and carefully padded filter holder bag. All optical components meet the strict Rollei quality standards "Engineered & Quality Controlled in Germany," which exceed industry standards.
