Description
The Diopter Frame 138mm from ARRI allows for select 138mm diopters of up to +2 to be used in a lightweight matte box such as the ARRI LMB 4×5 or LMB-25. The frame features two 4 x 5.65″ filter frames and fits into a 2- or 3-filter stage. A safety mechanism prevents the diopter from falling out of the frame, and two 1/4″-20 threads allow the frame to be attached to an articulating arm.
