The CPL filter also called Circular Polarizer, is mainly used to eliminate harmful non-metallic reflected light, and increase the color concentration. It also enhances blue skies, highlights whie clouds, makes the picture more thorough, improves image clarity anf overall creates a more expressive and vivid photo. It is also often used to shoot through glass, water and underwater scenery.
The ND filter also called 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. It also improves the color saturation of the picture, makes the picture more transparent and alive. You can also use a slow shutter speed to shoot some special effects, such as a mist of water, a light track at night, etc. When you shoot video in direct sun exposure, you can reduce the shutter speed by subtracting the lens, so that the video has the appropriate motion blur and looks balanced.
SCHOTT Optical Glass:
Uses German SCHOTT glass as its base material utilizing multiple grinding and polishing processes.
Double-sided and Multilayer Coating:
Nanometer-scale, double-sided, multi-layer vacuum coating process ensures a first-class waterproof, oil-proof, dust-proof, and anti-scratch protector.
Absorption of More Light:
Double-sided anti-reflection coating is deposited on the surface of the optical components by ion-assisted evaporation to reduce surface reflection ahd increase the optical transmittance.
Guarantee of Camera's Waterproof Performance:
The inside of the filter frame adapts to the threaded pattern that matches the camera's original design to ensure the camera's waterproof performance after the replacement.
Extremely Light CNC Aviation Aluminum Frame:
The filter doesn't affect camera performance.
High quality color coating
