The 49mm Freewell Base Ring for Brandon Li VND/CPL Basic and Pro Kits is the foundation of the Brandon Li magnetic locking filter ecosystem, allowing compatible filters to attach quickly and securely to supported camera lenses. Designed specifically for compatibility with Brandon Li VND/CPL Basic and Pro Kits, the base ring mounts directly to lenses with matching filter threads and enables fast magnetic filter installation during photo and video production.
Its modular design allows filmmakers and photographers to use a single Brandon Li filter kit across multiple lenses by adding additional base rings in different thread sizes. The magnetic locking system supports fast filter swaps while maintaining a lightweight and portable workflow for travel, handheld shooting, and run-and-gun production environments.
