    Marumi CINE&TV WSND-ES2.1

    The Marumi CINE&TV WSND-ES2.1 Filter is an improved flagship model by adopting an advanced ND coating technology with more potent adhesive force than the conventional vacuum deposition coating method.
    • Precise color neutrality over a wide range from visible to near-infrared light spectrum reproduces the color faithfully, especially by mitigating red casting, which is peculiar to sensitive digital image sensors.
    • Despite its single glass structure, the incomparable ultra-scratch resistance on the glass surface is firmly verified.
    • 128-Filter factor, 7-stops, 2.1-Optical density, ascertained color fidelity by ND coating (Specification values)
    • The upmost coating technology implemented;
    • 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 sheds 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 sustains a low reflection
    • Protective sealing on the edge makes easier handling, and it prevents inner reflection caused by the edge of the glass.
    • Made in Japan, ensured quality control guarantees optical precision of tolerances in replacing filters from different lot production.
