Eyebrow (Top Flag): Mounts to the top of the hood to block overhead glare and control ambient light spill. Hard Mattes (Masks): A set of clip-in hard mattes (typically a 6-piece set) designed to perfectly match your lens focal length, maximizing flare protection by restricting the field of view. Swing-Away Mechanism: Features a swing-away arm mounted to either 15mm or 19mm studio rods, enabling quick lens changes without having to disassemble the matte box. Professional Use Context The MB-18 requires a studio bridge plate and is optimized for heavy prime sets and large cinema zooms. It is highly favored for narrative, commercial, and documentary shoots where advanced light control and complex filter stacks are required.
