Each filter is made from high quality K9 Optical Glass and housed in an aerospace grade aluminum frame. The double-sided Nano multicoating ensures no color cast, and provides waterproof, dustproof, and anti-oil protection.
The extremely light weight (1.3g per filter) yet robust filters help to capture crystal-clear images and video footage, even in bright sunny daylight conditions.
The Neutral Density filter will help to slow down the cameras shutter speed and provide an equal light reduction across the entire image, while the Polarizing lens aspect removes unwanted reflections from non-metallic surfaces and saturates colors to provide better contrast. Each filter has laser etched indicators on the frame to help determine the polarization.
