NiSi Cinema 4" x 5.65" Explosion-Proof Protector Filter

The NiSi Cinema 4" x 5.65" Explosion-Proof Protector Filter is a clear filter coated with shatter-proof film to keep all of the pieces together in the event of high velocity impact. It is designed to protect your lens or other filters from projectiles, flying debris, or accidental collision with stationary objects. Its shatter-proof coating creates no additional coloration or contrast effect and requires no adjustments to exposure. It is constructed from water white glass for clarity and color accuracy. Each glass surface also includes one layer of nano-coating that helps to prevent reflections and glare. 

This filter is compatible with all leading brands of matteboxes that accept the 4x5.65" standard. The cinema filter also conforms to a 4mm maximum thickness, allowing it to fit into filter cages or slot into cageless designs. A leatherette pouch is included for storage and transport.
