Ulanzi MF01 77mm Magnetic Filter Adapter Ring

The Ulanzi MF01 77mm Magnetic Filter Adapter Ring allows fast and effortless attachment of magnetic filters to compatible lenses, providing photographers and videographers with a secure, lightweight, and time-saving solution for quick filter changes in dynamic shooting environments.

The Ulanzi MF01 Magnetic Filter Adapter Ring is designed to convert standard 77mm threaded lenses into a magnetic filter system, enabling instant mounting and removal of magnetic filters without repetitive screwing. Made from durable aluminum alloy, the adapter is lightweight yet robust, ensuring long-term reliability while protecting your lens threads.

Once screwed onto the lens, the MF01 allows magnetic ND, CPL, mist, and other compatible filters to snap on and off smoothly, making it ideal for outdoor, travel, landscape, and video work where lighting conditions change rapidly. The adapter performs optimally on wide-angle lenses (20mm or wider on full-frame), minimizing vignetting while maintaining image quality. Available in multiple size variants (67mm, 72mm, 77mm), the MF01 offers broad compatibility across different lens setups, helping streamline your workflow and boost creative efficiency.
