The Wooden Camera Zip Box is a compact, lightweight filter holder for a single 4 x 5.65″ (P-size) filter. Zip Box is useful for handheld, stabilized, and drone filming where a small profile and low weight are needed. Wooden Camera’s rubber hood is designed to work with many wide-angle lenses without vignetting. A unibody rubber design and stainless steel clamp provide a secure grip by clamping directly onto the front of DSLR-style lenses with exterior diameter of 80 to 85mm. The package also includes a set of step-up rings for mounting on lenses with an outer diameter smaller than 80mm.
