The filter has a hard coating that protects the lens and sensors by preventing UV light from entering the camera. It blocks out blue light which prevents images from looking bluish or whitish when shooting in open spaces like at sea or in large fields. High transmittance, doesn't affect image sharpness.
The ND filter also called the Reducing Light filter, or Neutral Density filter reduces the amount of light in very bright conditions so that the camera can choose the correct exposure value and avoid excessive exposure.
The CPL filter eliminates glare from reflective surfaces, such as water, snow or even glass windows when flying outdoors. It increases color saturation and image clarity to create more expressive and vivid photos. Rotate to change its polarizing effect. Eliminates polarization, improves image definition and vividness.
The Hybrid ND-PL filter prevents unwanted reflections. It also saturates colors and improves image sharpness to create more vivid photos. It reduces the shutter speed and prevents overexposure to create smooth, cinematic, aerial videos. Rotate to change its polarizing effect.
The frame is made of high-quality aluminum alloy, light yet sturdy
The filter uses professional optical glass as its base material, which has been ground and polished multiple times to create a low refractive index for professionals to capture color accurate photos.
The filter's double-sided, multi-layered coating repels water and oil, which makes it easy to keep clean. The filter's hard coating also makes it scratch resistant.
The filter's optical glass contains a refection reducing coating to maintain color accuracy and balance.
