The new Freewell Circular Polarizer (CPL) 4K Series Filter helps remove unwanted reflection from reflective surfaces such as water or glass. It also enhances colours and contrast by reducing glare from water, snow or clouds. It will quickly fit the Phantom 4, Phantom 3 Pro and Phantom 3 Advanced (not Phantom 4 Pro or Phantom 3 Standard) after unscrewing the stock UV filter. If you need just a CPL on its own without ND filters, this is the ideal solution.

It features:

• HD optical glass with Multilayer coating 
• Easy grip aluminum alloy filter ring construction
• Rotatable ring to enable easy selection of polarising angle 
• Lightweight (6gm) with no effect on gimbal balance
• 4K Series filters are specifically designed for professional quality 4K video and high resolution still images
• Includes padded metal tin for secure storage

Not everyone needs a full pack of filters, particularly if you're mainly shooting stills. This high quality CPL will give you all the benefits of a well-constructed polarising filter to enhance both video and stills.

Please note: A polariser will achieve the maximum benefit when the sun is at right angles to your lens.
