    Marumi EXUS Circular PL

    The Marumi EXUS Circular Polarizer is a flagship model polarizer especially well-suited to whom a high-polarization has taken precedence in the first place in polarizing (99.5%* degree of linear polarization under 400nm; *polarizing film only)
    • Contrast-enhanced, more saturation provided, and blue sky will be vividly deepened.
    • The High Transmission Circular Polarizer (HTC) performs approximately 93.6% maximum transmission rate and an averagely of 44%. (2.3 x Filter Factor, 1.2 stops, 400-700nm)
    • The upmost coating technology implemented, eighteen layers in total on both sides;
    • Anti-static coating (ASC) works wonders on the surface of a glass. Dust and dirt adhered to the surface can be quickly and easily blown off.
    • Water-/Oil repellent coating shed water off simply also by the air blower. Nuisances such as sweats, skin crème, lotion, fingerprint, or compounded grease stains will be wiped off.
    • ASC Coating and light-blocking ridges inside the ring reduce reflection rate under 0.6%. (420-680nm average)
    • Realized an ultra-thin aluminum rotating structure to avoid vignetting.
    • Teflon coating on male threads makes attach-/detachment to/from the lens more smooth.
    • Knurling embedded on the lightweight frame enables easy and smooth handling
    • Made in Japan, indurated lamination technology by decades of technical succession.

    What are the benefits of using a polarizing filter?
    Why is polarizing filter recognized among most photographers as an essential must-have filter? Does Photoshop or other equivalent editing tool work instead of polarizer?

    A polarizing filter allows you to;
    - control reflections from non-metallic objects; the surface of water, window, or glossy coating/painting.
    - prevent and reduce glare, still however, allow plenty of light through. It also makes subjects underwater transparent.
    - Enhance color saturation and contrast, especially under a scene of deep blue sky, vivid white clouds, spring greenery, or autumn color of leaves.

    Have you ever experienced, when taking landscape photography, ending up with a little different color from the actual landscape you have seen? The sky must have been more vivid and bluish in your eyes.
    A polarizing filter can properly contrast the crystal blue sky and the white clouds. 
    Many photographers predominantly carry a polarizing filter, particularly for landscape photography next step after Lens Protector/UV filter in terms of protection, for some reason.
    The effects of polarizers cannot be easily mimicked with digital editing. Carrying a polarizer makes your image more vivid and clear, turning the actual landscape you've seen into your picture.
    The two images below obviously show the difference of impact with/without polarizing effect in contrast.

    Another two images show how the polarizing effect changes the image, eliminating light's reflection.

    Photographers should keep in mind that a polarising filter will reduce a certain amount of light passing through the camera body in exchange for giving a polarizing effect.
    Therefore, it is better not to use a polarizer under poor light conditions.
    It is also better to consider attaching a High Transmittance Circular Polarizer (HTC) that is equivalent close to one F-stop while other conventional polarizers are equivalent to 1.5 stops.

    In post-production, the Polarizing effect cannot be reproduced because they change the light entering your lens
    Those are the reason why the Polarizing filter is a must-have filter.
