The Extra Rotatable Filter Stage gives the possibility to rotate an additional 6.6x6.6 filter 360°. It attaches to the Basic Module by sliding to the rear and fixed by two thumb screws without the need for any tools. For extreme lightweight applications such as gimbal and Steadicam the separate single filter stage works perfectly in conjunction with any clamp or the tilt and flex adapter. Each filter frame is secured with an extra tray catcher which holds the filters in place perfectly.
