ARRI Diopter Stage 138mm
The ARRI Diopter Stage is an intermediary filter holder placed between your LMB series matte box and clamping adapter ring. It allows one to use 138mm diopters/proxars (or any other 138mm filter) in conjunction with 4×5.65 filters. It can be used with any LMB 4×5 filter sized matte box. The stage also has a built-in friction wheel for adjusting the placement of split diopters.
