The LMB 4×5 Rotatable Filter Stage from ARRI is compatible with the LMB 4×5 matte box. This third filter stage rotates 360°, enabling you to adjust the positioning of your polarizer, graduated, or effects filter. It can also be used as a standalone filter stage with an LMB 4×5 clamp adapter.
The stage has an integrated tray catcher to prevent the filter from sliding through the bottom of the stage when the side lock is loosened. A 4×5.65″ filter frame is included with this stage.
