The Freewell base ring is designed for lenses with a 52 mm thread and forms the core of the modular Real Locking system. Thanks to precision-milled aluminum, it ensures firm and stable mounting of VND/CPL filters and compatible caps. The package includes a protective cap with latches and integrated NFC for instant access to manuals, warranty, and support directly from your phone.
The system is expandable to multiple diameters (49–82 mm), so you can use one set of filters across different lenses and cameras. The cap effectively protects against dust, scratches, and impacts during transport, while the ring minimizes play and speeds up accessory changes.
