Freewell 72 mm Base Ring with Cap for Real Locking VND

The Freewell 72 mm base ring is an essential part of the Real Locking VND/CPL system, designed for fast, secure filter mounting on your lens. Made from precision-machined aluminum, it delivers a solid fit and full compatibility with other system components — from VND filters to protective caps. The 72 mm version is made for lenses with a 72 mm thread and also helps you expand the system to support smaller lens diameters.

NFC Cap for Protection and Quick Access

The set includes a dual-lock protective cap with a built-in NFC module. Just tap it with your smartphone to instantly access the user manual, warranty details, and support materials. The cap also helps protect your lens or mounted filter from dust, scratches, and accidental damage during transport and storage.

Built for Easy System Expansion

This base ring is the foundation of the Freewell Real Locking filter setup. The system is available in multiple sizes, from 49 mm to 82 mm, making it easy to match different lenses and use one filter setup across multiple cameras while keeping your workflow smooth and convenient.
