ARRI's LMB 6x6 Tilt and Flex Adapter 80-156mm can be used to bridge any gap between extending front elements on your lens and an LMB 6x6 matte box. This adapter is compatible with lenses incorporating a front outer diameter between 80 and 156mm.
The Tilt and Flex Adapter will also compensate for the tilting angle created when using a Swing-Away Tilt Module with the LMB 6x6 matte box. An interface at the bottom of the adapter can accommodate either the LMB 15mm or LMB 19mm Studio Rod Adapter.
