ARRI MB-16 Production Matte Box

ARRI MB-16 Production Matte Box is a front-mounted shading device designed for 16mm and 35mm cinema lenses that accepts a 4x4 filter frame. Listed in ARRI's archival documentation as the 4x4 Matte Box 16 (MB-16), this model is intended to mount standard square/rectangular filters on-set to control glare and flare in production environments. It integrates with ARRI's accessory ecosystem, providing a straightforward interface for inserting and aligning filters and flags in front of the lens. By reducing stray light and protecting image contrast, the MB-16 helps maintain consistent exposure and color rendering across takes when working with fast lenses or challenging lighting. As part of ARRI's lineage of production matte boxes, the MB-16 offers a practical, field-ready option for filmmakers using 16mm or 35mm cameras who require reliable front-end filtration without complex swing-away configurations. Note: While older in design compared with newer ARRI matte boxes, the MB-16 remains a recognized option for projects that require a dedicated 4x4 filtration solution on 16mm or 35mm systems.
