Lens Base Ring Freewell FW-L1-BL52 52mm with Lid for Real Locking VND

The Freewell 52 mm base ring with lid for Real Locking VND provides a secure mount for Real Locking VND/CPL filter systems on lenses with a 52 mm thread. Manufactured from precision-milled aluminum, the ring ensures stable attachment and compatibility with other system components, while the included protective cover with built-in NFC offers fast access to product information and helps protect the lens or mounted filter from dust and scratches during transport.

Advantages

The aluminum construction delivers reliable strength with low weight, and the Real Locking design ensures quick and secure filter mounting and removal.
