UV filter reduces disorder and improves image contrast by minimizing the amount of ultraviolet light. ND filters reduce the amount of light reaching the sensor without affecting the color and allow slower shutter speeds under high exposure to the CPL sun filter eliminates unwanted reflections on non-metallic surfaces such as water or glass, as well as sun reflections. It increases color saturation, creating rich panoramic images and reducing the amount of light entering the lens. The filter frames are made of high precision CNC aviation aluminum and feature a multi-coated optical glass.
