NiSi Cinema True Protector Explosion-Proof Filter for Cooke S7i 18mm&21mm

NiSi True Protector Explosion-Proof Filter  is designed to provide enhanced protection for your Leitz lens at all times including when photographing or recording under conditions with an elevated potential of damage to your lens’s front element. Each of its surfaces features a shatter-proof coating, which creates no additional coloration or contrast and requires no adjustments to exposure.

The NiSi True Protector Explosion-Proof Filter  features a screw-in design and is constructed from water white glass for clarity and color fidelity.  The filter has a Professional Explosion-Proof Layer that protects the lens as the glass does not shatter like normal glass, is Double-Sided Anti Reflective Waterproof Coated, and has no loss in sharpness. The glass features a cinema edge seal for durability and is compatible with the lens cap included with your  lens.
