Wooden Camera Zip Box Double 4x5.65 (80-85mm)

Zip Box Double 4x5.65 (80-85mm) holds two 4x5.65 inch (100 x 114mm) filters and clamps directly onto the front of a lens between 80 and 85mm in outside diameter. Measure by the lens barrel's outside diameter, not the filter thread size, when picking this against the other three sizes in the line.

Stainless-steel components and a unibody rubber housing keep it durable while weighing about the same as a single filter, which is the point on a gimbal or drone package where every gram of front-heavy weight fights the motors.
