Arri LMB 4×5 Clamp-On Lightweight Matte Box

The ARRI LMB 4×5 Clamp-On Lightweight Matte Box is a highly modular, industry-standard filtration system designed for everything from small gimbal setups to full-scale studio productions, adding advanced features like an extra rotatable filter stage and a tilt-and-flex adapter.

Filter Support: At its core, the basic module is a two-stage matte box that accommodates 4 x 4 and 4x 5.65 filters.
Expandable Stages: You can easily add a third non-rotating or rotating filter stage to the stack.
Universal Compatibility: It supports lens diameters ranging from 62mm to 165mm through interchangeable clamp adapters.
Advanced Flare Control: Includes a carbon fibre top flag with extendable “eyebrows” and optional side flags that fold flat for compact storage.
Mounting Versatility: While this specific model is a clamp-on version, it can be converted for 15mm LWS or 19mm studio rod support using separate modules
