Wooden Camera Zip Box Pro 4x5.65 (Clamp On)

The Zip Box Pro Clamp On is a compact matte box for lenses up to 114mm in diameter, holding three 4x5.65 filters loaded from the front and secured by a spring-loaded latch. A lightweight carbon-fiber top flag covers the front of the box between takes and pulls free by loosening the top thumbscrew and lining up the tab with its key slot.

The rear opening swaps between clamp-on backs sized for 114, 110, 104, 100, 95, 87, 85, and 80mm lenses by loosening four thumbscrews, and the same body accepts a Zip Box Pro Swing Away Back for lens changes on the fly.
