The Moviemate Mag Matte Box Master Kit by Kase is a professional camera accessory for filmmakers and videographers that offers precise light control and lens protection. This comprehensive kit includes a magnetic matte box system that securely connects to compatible lenses without traditional mounting hardware, allowing for quick setup and removal. Made from durable aluminum alloy with a matte black finish, the matte box measures approximately 15.2 cm in width, 12.5 cm in height, and 8.7 cm in depth, with a total weight of 480 g. It features two filter stages for standard 4x4 inch (10.16x10.16 cm) square filters and a rotating filter stage for circular polarizers or graduated filters. The magnetic attachment system ensures stable positioning during quick lens changes and is compatible with lenses ranging from 67 mm to 95 mm filter thread diameter via included step-up rings. The kit includes several French flag attachments to shield against stray light, a lens support clamp for heavier setups, and storage bags for organized transport. Designed to minimize vignetting with wide-angle lenses, the matte box effectively reduces lens flare and enhances contrast in various lighting conditions. The anodized surface resists scratches and corrosion, maintaining a professional appearance over extended use. All components feature precise machining for consistent alignment and reliable performance in studio or field use. This system is ideal for DSLR, mirrorless, and cinema cameras where controlled lighting and filter management are essential for high-quality video production.
