The innovative variable PolarView® ND filter is based on liquid crystal technology

The level of ND is controlled electronically, there are no moving parts. The PolarView® ND filter can be built-in inside the camera, integrated into a smart lens adapter, or positioned in front of the lens (the latter model currently under development). Designing the electronics for remote or automatic control is attractive for gimbal and crane mounted camera operation.
