Φίλτρο ουδέτερης πυκνότητας (ND4) Freewell FW-L1-ND4 για Real Locking VND

The Freewell ND4 filter for Real Locking VND reduces light by 2 stops to help control exposure when shooting in brighter conditions.

Installation is quick and tool-free via side tabs that snap the filter onto the L1 base ring or onto the Real Locking VND/CPL extension. A compact shockproof case protects the filter during storage and transport, and the included cleaning cloth helps keep the optics clear.
