Lanparte Hard Matte Set for ARRI LMB-25, LMB-15, LMB-5 and MB-19 Matte Box, 5-Pack

This Set of 5 Mask of Lanparte UMB-01 and UMB-01 Pro are compatible with ARRI LMB-5/15/25 & MB-19 Matte Boxes. Each mask mounts on the front of your matte box and covers one of five focal length ranges. The mask is essentially a solid light blocking piece of ABS plastic with a window corresponding to the field of view of the wider lens in the range as it intersects with the leading edge of your matte box. This allows the mask to block almost all extraneous light from entering your matte box, preventing veiling and glare from wreaking havoc on your image.
