Wooden Camera Zip Box Double 4x5.65

The Zip Box Double holds two 4x5.65 (100x114mm) filters and clamps directly onto the front of the lens in one of four sizes: 80-85mm, 90-95mm, 100-105mm, and 110-115mm. Its lens-shade design covers even wide lenses and large sensor formats without vignetting - measure by outside lens diameter, not filter thread size, when picking a size.

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