Freewell 72 mm Base Ring & Cap

The Freewell 72mm base ring is an essential part of the Real Locking VND/CPL system, enabling fast and secure mounting of filters to lenses with a 72mm thread. Built from precision-milled aluminum, it ensures durability and reliable performance. The included two-snap cap features an NFC module that grants instant access to manuals, warranty details and support by simply tapping your smartphone. The cover shields your lens or filter from dust, scratches and mechanical damage, while the base ring allows easy expansion to other lens sizes within the Freewell Real Locking system.
