The LMB 4x5 Basic Module from ARRI is the starting point for the modular LMB 4x5 lightweight matte box, a configurable filtration and flare suppression system for professional filmmaking setups. The module consists of an LMB 4x5 back plate with filter guides, a sunshade, a pair of 4 x 5.56" filter frames, a pair of flag holders, a tray catcher, and a mask. By means of separately available clamp adapters, the module can be matched to various lens diameters. The module can be extended by adding other LMB 4x5 parts.
